Portable fission reactor

2024-12-09T21:35:17Z

Khaylain: Removed claim it got a significant buff to power generation, as 1.1 PFuR has the same power generation as 2.0.7 PFiR

{{Languages}}
{{:Infobox:Portable fission reactor}}
'''Portable fission reactors''' are advanced power generating modules for [[modular armor]], [[power armor]], [[power armor MK2]] and the [[spidertron]]. They generate 750kW of power, equivalent to 25 [[portable solar panel]]s, while taking up only a 4×4 area in the equipment grid.

Portable fission reactors are an unlimited source of energy and require nothing to power them.

Portable fission reactors are essential items for power armor and power armor MK2, as running the many other modules in these armors would take far too many solar panels to be practical.

== History ==
{{history|2.0.7|
* Introduced.
** Functionally a replacement for the 1.1.110 [[portable fusion reactor]].
** All portable fusion reactors crafted before 2.0.7 have been turned into portable fission reactors.}}

Replay system

2023-06-29T16:19:59Z

Khaylain: Added info about where the setting is located to avoid confusion.

{{Languages}}
== Overview ==

A replay is a file stored within the game save, containing any information needed to repeat (replay) a game from start, in a movie-like fashion. This feature is to allow players to view how their world came to be.

== Creating & playing a replay ==

Replays can be automatically generated as the map is played, behind the scenes. To enable this, the "Record replay" option needs to be checked when starting a new game. This setting is in the top right when selecting game modes (freeplay, scenarioes, etc.) before map settings. Replays have rather strong limitations, see below.

Playing a replay will play back in chronological order the actions taken in the world, as if the player was recording. The speed of playback can be increased or decreased to fine-tune the viewing experience.

To play replays, from the main menu go to Single player → Load game, then find the ▶ Start replay button in the upper right.

=== The replay GUI ===

A simple control GUI is available to control replay playback:

[[File:replay GUI.png]]

The top bar shows the position in the replay out of the total time of the replay. The buttons allow to:
* Pause/play the replay
* Slow down playback
* Speed up playback

In multiplayer replays it is also possible to change the viewpoint player via the dropdown. Furthermore, {{Keybinding|F10}} can be used to switch to the next viewpoint player in the list.

== Limitations ==

* Replays for worlds created in older versions cannot be played. Downgrading is needed to view the replay.
* Adding/removing mods to the save will also break the replay.
* Playback view is locked to the character in singleplayer.
* There is no way to skip ahead, the entire replay must be watched up until the point of interest.
* Re-winding (A.K.A. Going backwards in time ) is not possible.

== Advanced features ==

* The game can be saved at any time during playback, thus it is possible to play again from any time during the replay.
** This also allows to inspect the state at that point in time without zoom or movement limitations.
* Changing the script files inside the save will not invalidate the replay. This can be used to add scripts that do not affect the game state, such as taking screenshots in the background as the replay runs. Scripts that affect the game state (e.g. creating entities) will break the replay.
* Converting a save to a scenario and then starting a new game from that scenario restarts the replay at that point. This can be used to begin recording from a point after initial save creation, e.g. after mod or version changes have invalidated the previous replay. These are the steps to convert a save to a scenario and then start a new save game with replay enable:
** Main menu → Map editor → Convert save → Select the save file → Convert
** Main menu → Single player → New game → Select the scenario with the save name in the "User scenarios" → Check "Record replay" in the top right → Play

== 0.17.0 ==
Date: 26. 02. 2019
=== Major Features ===
* New quickbar (more in Gui section)
* Added shortcut bar that allows quick access to certain game features, such as toggling alt mode, creating blueprints, or turning off personal roboport
* New gui style with final version of some parts of the GUI (More in Gui section)
* Added clipboard functionality. (Control + C, Control + X, Control + V activate appropriate tools) Shift + mouse wheel allows to cycle the clipboard history.
* Added undo functionality (Control + Z). Supports manual entity building and by blueprints and manual mining and usage of deconstruction planner.
* Reworked the Map Editor so it's now part of the standard game and can be toggled at will using the '/editor' command.
* Support for mod synchronisation when joining multiplayer game. Works as long as the used mods are on the mod portal.
* Fight changes. Enemy projectiles are dodgeable and slowdown/damage the target over time. They also leave splashes on ground that have the same effect.
* Rich text tags. These tags can be used almost anywhere: Chat, station names, save names, custom ui and probably a few places we didn't think of.
** They allow changing color, font, images and location/blueprint/armor/station/locomotive linking through chat. (More in features)
* Fluid mixing prevention. Actions that fail as they would lead to fluid mixing (like building a pipe, changing recipe, rotating etc.) produce an error message as flying text.
* Replaced First steps campaign with Introduction campaign, available from the Start campaign menu.
=== Features ===
* Trains can be blueprinted and deconstructed.
* Trains can be given temporary stations (by Control+clicking the map). Temporary station is automatically removed once the train departures from it.
* Train stops without conditions work as waypoints. (the train doesn't stop at those)
* Added Passenger present and Passenger not present wait condition to the train conditions.
* If building of entity/blueprint fails, the reason of it is pinged as flying text.
* Map pings. Ctrl+Alt+click on the map to show a ping in all players maps at that location.
* Basic image tags format is [img=<image path>] where image path can use item, entity, technology, recipe, item-group, fluid tile, virtual signal achievement or utility icon.
** For example [img=item/iron-plate] or [img=item.iron-plate]. The "." instead of "/" usage is to make it usable in save names.
** Additionally, items/entities/technologies/recipe/item-group/fluid/tile/virtual signal or achievement can be linked directly by [item=iron-plate], [recipe=iron-plate], or [entity=small-biter] to provide tooltip for the appropriate object.
* Blueprint/special item tags.
** Shift clicking the icon in chat will create an item and place it in the cursor.
** Format is [special-item=blueprint string], eg: [special-item=0eNp1jtEKwjAMRX9l5rnCxkShvyIi3YxboU1Lm4lj9N9N54sv5iFwL/eeZIPBLRiTJQa9gR0DZdDXDbKdyLjq8RoRNFhGDwrI+Ko4GcoxJD4O6BiKAksPfIPuyk0BElu2+CXtYr3T4gdMEvjHUBBDllqgelVQrYJVdqnE/br+eVaBM1ITb0bnQvNMwTc8YzPOhiZ0YTpI5oUp78BL33YnmbY/l/IBb4pSQQ==].
** These tags also work with deconstruction and upgrade planners.
* Map ping tags: Created by shift-clicking the ground/map when the chat is open. Format is [gps=x,y], eg [gps=10,30] will show a map ping in all players maps at location 10,30.
** Clicking the icon in chat will open the map on the specified location.
* Font tags: Format is [font=debug-mono]mono text[/font].
* Color tags: Format is [color=1,0,0]red text[/font]
* Fast replacing pipes by pipes to ground similar to underground belts.
* When multiple versions of the same mod are installed you can select which version you want to use.
* The sync mods with save/multiplayer game feature can now sync mod startup settings as well as mods.
* Added support to import and export permissions.
* Closing opened items (blueprint books/armor) now remembers what GUI you previously had open.
* Filter inserters can be set to whitelist or blacklist filters.
* Added belt immunity equipment.
* Added upgrade planner.
* Added steam networking support for steam users.
* Added RGB support for Logitech hardware.
* Robots can blow up cliffs.
* Wave defense scenario has been reworked to support multiple rounds and a procedurally generated map.
* Added a research queue that becomes available after the player has finished the game by launching a rocket with satellite.
=== Minor Features ===
* Warning icon for automated trains that are out of fuel.
* Added 250 and 1000 hours precision intervals into statistics.
* Using deconstruction planner is incorporated in the latency hiding.
* Changed personal roboports so they won't send construction robots if you're driving in a vehicle that they can't keep up with or if in a train in automatic mode.
* Added an option to ignore mouse events when using accessibility zoom feature on macOS.
* Added support to change multiplayer config settings runtime.
* Added support to edit the whitelist, banlist, and admin list when hosting a multiplayer game.
* Added the Admin GUI (openable through /admin in the console) to manage multiplayer players.
* Landfill can be built by robots and be included in blueprints.
* Blueprint items taken from blueprint library will not move to player inventory when Q is pressed, but can be moved to any slot explicitly. (Same as with clipboard items)
* When selecting any item to the cursor from some of the player inventories. As long as the item is being held, hand icon is shown on the slot it was taken from. The hand prevents any other item to be inserted into the slot as long as the player cursor isn't cleared.
* When holding radar in cursor, area covered by existing radars is also highlighted on minimap.
* Configurable (in gui), the count of rolling stocks shown in the train visualization.
* Added two levels of shallow water tiles (only placed by map editor, not generated). Enemies and vehicles can travel over shallow water.
=== Graphics ===
* New graphics for:
** accumulator
** biters, spitters, worms, spawners
** chests
** electric poles and substation
** map edge transitions
** rocket silo
** transport belts, underground belts, splitters and transport belt circuit connector
** trees
** turrets (gun, flamethrower and laser)
** walls and gates
* laser turrets, personal laser defense and distractor robots now use new laser beams.
* Highlighting inserters that would interact with selected/previewed entity.
* Showing shield bars above health bar for relevant entities.
* Single vertical pipe is shorter.
=== Gui ===
* New final versions of several important GUI screens (Quick bar, Train Schedule, Load/Save Game, Settings, Map Generator, Research, Mods)
** Other screens than the mentioned ones (more than 100) have inconsistencies and will be updated in future minor updates.
* The quickbar is no longer an inventory, instead it can only hold shortcuts it items in inventory or blueprint library.
** The quickbar now has 10 pages of shortcuts.
** Player inventory increased by 20 slots to compensate. Toolbelt research further increases the player inventory.
* In the map, station and tag selection is now visualized by the standard Factorio selection box graphics instead of highlighting.
* Added interface option: When selecting a buildable item from the quickbar or when using the pipette tool, if you have no items of that type, a ghost will be placed in the cursor instead.
* When something is not buildable (manual or blueprint building), the reason of why it isn't buildable is shown as flying text over the cursor when the build is attempted.
* Only compatible results of a furnace are manually placeable in the result slot. (Mainly to avoid confusion of new players)
=== Optimisations ===
* Modernized and optimized rendering backend. The game now uses DirectX 11 or OpenGL 3.3 Core and requires DirectX 10 class graphics card.
* DirectX backend doesn't keep backup of all sprites in RAM anymore.
* Added high quality texture compression to reduce amount of video memory consumed by the game and increase overall rendering performance.
* Added texture streaming so that adding more sprites does not necessarily increase GPU requirements.
* Improved game startup performance when using a large amount of technologies with deep dependency trees (it's now 67,000 times faster).
* Optimized rendering of logistic overlay when zoomed in to map. ([https://forums.factorio.com/60659 more])
* Optimized rendering of turret ranges when zoomed in to map. ([https://forums.factorio.com/58991 more])

** The starting area contains only iron, copper, coal and stone, in very predictable amounts. Uranium and oil are excluded from the starting area.
** Resource generation settings now have a much more dramatic effect. Increased the number of steps for each setting.
** Ore patches are slightly less frequent but richer.
** There will be a more balanced amount of resources within a large enough region.
** Many other small tweaks.
* Biter generation changed significantly:
** Biter richness slider removed, biter placement is only configured by size and frequency settings.
** Biter generation settings now have a much more dramatic effect. Increased the number of steps for each setting.
** Biter bases will increase in size, frequency and number of worms depending on the distance from player spawn.
** Worm size increases depending on the distance from player spawn.
** Small biter bases are now closer to the player spawn.
** At large distances from player spawn, biter base frequency is lower than before but biter bases are larger.
** Other small tweaks.
* Terrain generation changed significantly:
** Water is generated as large lakes instead of swamps.
** Tile generation improved. Tile placement respects biomes better.
** More predictable cliff placement.
** Better controls in the map generator GUI for water, tiles and cliffs.
* New map terrain type selectable: Island. Launch the rocket with only a limited amount of resources available on the map.
* Default resolution of the game is now 1920x1080.
* Increased player reach from 6 to 10.
* Inserters are putting science packs to the lab even when there is no research in progress or when the research doesn't need that particular pack.
* Default_request_amount removed in all places where it was used. Default logistic request is 1 stack, unless changed by the setting "Default request is 1".
* All personal equipment stack sizes changed to 20.
* Placing a tile will now clear any tile ghosts at that position. ([https://forums.factorio.com/59721 more])
* It is allowed to use unicode characters in save names.
* Recipes that have more ingredients than the assembling machine allows are now shown as red instead of not present when selecting the recipe.
* When the "Made in" row is shown in the recipe tooltip, player icon is added to the list when it is craftable by player.
* Increased ghost time to live of ghosts from 1 hour to 1 week.
* Since the catalysts have been tweaked, the kovarex enrichment process can now be used together with productivity module.
* Tile construction jobs are being handled by robots separately from entity building jobs, to prevent entity ghosts not being built due to large number of tile ghosts.
* Switched key bindings from key codes to scan codes. This solves an issue with bad default key bindings on layouts that are not similar to US QWERTY (ie. AZERTY).
* Armor no longer uses durability and all armor now has a stack size of 1.
* Manually putting modules into machines that are requesting modules from the logistic network will reduce the modules requested.
* Increased maximum train stop length from 50 to 100 characters so it can fit at least 3 tags in most cases.
* Items consumed by hand crafting are counted in item production statistics.
* Added --disable-migration-window command-line option to disable the "migrated content" gui.

* Removed Wood from the game (And raw wood renamed to Wood).
* Added rotation smoothing to biters.
* Chests and wooden power poles are no longer usable as fuel.
* Burner efficiency is set to 100% for all entities and fuel value is halved to simplify calculations. This should not change game balance.
* Removed the hardness/mining power mechanics, we just have a mining speed and mining time now.
* Manual mining speed times of various entities will differ a bit, but probably not in a noticeable way.
* Stone and other ore mining speed has been unified to be 1 (apart uranium ore, which is 2 and shown as 200% mining time)
* Mining drill speed is now shown in the form of <x>/s (0.25/s for burner mining drill, 0.5/s for electric mining drill), the relative mining speeds of the mining machines have been decreased a little so the numbers are rounded nicely (0.28 -> 0.25 and 0.525 -> 0.5).
* Renamed the whitelist and banlist to server-whitelist and server-banlist.
* Added server-adminlist that's used to determine which people are admins when hosting any multiplayer game. This is synced both ways when hosting any game.
* Removed "admins" from the multiplayer server-settings file - they're now handled through server-adminlist.
* "Z" (drop item) will drop single items into what ever entity is selected instead of only dropping on the ground.
* Stickers can by applied onto cars and tanks now.
* Changed the chat gray-out mechanism. It always greyed-out after 5 seconds to 70% alpha, and then stayed depending on the setting. Now it stays 100% and only greys out away in the last 2 seconds.
* Placing entities or paths removes tree stumps and biter corpses.
* Removed New Hope campaign.

Date: 26. 02. 2019
=== Major Features ===
* New quickbar (more in Gui section)
* Added shortcut bar that allows quick access to certain game features, such as toggling alt mode, creating blueprints, or turning off personal roboport
* New gui style with final version of some parts of the GUI (More in Gui section)
* Added clipboard functionality. (Control + C, Control + X, Control + V activate appropriate tools) Shift + mouse wheel allows to cycle the clipboard history.
* Added undo functionality (Control + Z). Supports manual entity building and by blueprints and manual mining and usage of deconstruction planner.
* Reworked the Map Editor so it's now part of the standard game and can be toggled at will using the '/editor' command.
* Support for mod synchronisation when joining multiplayer game. Works as long as the used mods are on the mod portal.
* Fight changes. Enemy projectiles are dodgeable and slowdown/damage the target over time. They also leave splashes on ground that have the same effect.
* Rich text tags. These tags can be used almost anywhere: Chat, station names, save names, custom ui and probably a few places we didn't think of.
** They allow changing color, font, images and location/blueprint/armor/station/locomotive linking through chat. (More in features)
* Fluid mixing prevention. Actions that fail as they would lead to fluid mixing (like building a pipe, changing recipe, rotating etc.) produce an error message as flying text.
* Replaced First steps campaign with Introduction campaign, available from the Start campaign menu.
=== Features ===
* Trains can be blueprinted and deconstructed.
* Trains can be given temporary stations (by Control+clicking the map). Temporary station is automatically removed once the train departures from it.
* Train stops without conditions work as waypoints. (the train doesn't stop at those)
* Added Passenger present and Passenger not present wait condition to the train conditions.
* If building of entity/blueprint fails, the reason of it is pinged as flying text.
* Map pings. Ctrl+Alt+click on the map to show a ping in all players maps at that location.
* Basic image tags format is [img=<image path>] where image path can use item, entity, technology, recipe, item-group, fluid tile, virtual signal achievement or utility icon.
** For example [img=item/iron-plate] or [img=item.iron-plate]. The "." instead of "/" usage is to make it usable in save names.
** Additionally, items/entities/technologies/recipe/item-group/fluid/tile/virtual signal or achievement can be linked directly by [item=iron-plate], [recipe=iron-plate], or [entity=small-biter] to provide tooltip for the appropriate object.
* Blueprint/special item tags.
** Shift clicking the icon in chat will create an item and place it in the cursor.
** Format is [special-item=blueprint string], eg: [special-item=0eNp1jtEKwjAMRX9l5rnCxkShvyIi3YxboU1Lm4lj9N9N54sv5iFwL/eeZIPBLRiTJQa9gR0DZdDXDbKdyLjq8RoRNFhGDwrI+Ko4GcoxJD4O6BiKAksPfIPuyk0BElu2+CXtYr3T4gdMEvjHUBBDllqgelVQrYJVdqnE/br+eVaBM1ITb0bnQvNMwTc8YzPOhiZ0YTpI5oUp78BL33YnmbY/l/IBb4pSQQ==].
** These tags also work with deconstruction and upgrade planners.
* Map ping tags: Created by shift-clicking the ground/map when the chat is open. Format is [gps=x,y], eg [gps=10,30] will show a map ping in all players maps at location 10,30.
** Clicking the icon in chat will open the map on the specified location.
* Font tags: Format is [font=debug-mono]mono text[/font].
* Color tags: Format is [color=1,0,0]red text[/font]
* Fast replacing pipes by pipes to ground similar to underground belts.
* When multiple versions of the same mod are installed you can select which version you want to use.
* The sync mods with save/multiplayer game feature can now sync mod startup settings as well as mods.

* Closing opened items (blueprint books/armor) now remembers what GUI you previously had open.
* Filter inserters can be set to whitelist or blacklist filters.
* Added belt immunity equipment.

* When holding radar in cursor, area covered by existing radars is also highlighted on minimap.
* Configurable (in gui), the count of rolling stocks shown in the train visualization.
* Added two levels of shallow water tiles (only placed by map editor, not generated). Enemies and vehicles can travel over shallow water.

** Other screens than the mentioned ones (more than 100) have inconsistencies and will be updated in future minor updates.
* The quickbar is no longer an inventory, instead it can only hold shortcuts it items in inventory or blueprint library.
** The quickbar now has 10 pages of shortcuts.
** Player inventory increased by 20 slots to compensate. Toolbelt research further increases the player inventory.
* In the map, station and tag selection is now visualized by the standard Factorio selection box graphics instead of highlighting.
* Added interface option: When selecting a buildable item from the quickbar or when using the pipette tool, if you have no items of that type, a ghost will be placed in the cursor instead.
* When something is not buildable (manual or blueprint building), the reason of why it isn't buildable is shown as flying text over the cursor when the build is attempted.
* Only compatible results of a furnace are manually placeable in the result slot. (Mainly to avoid confusion of new players)
=== Optimisations ===
* Modernized and optimized rendering backend. The game now uses DirectX 11 or OpenGL 3.3 Core and requires DirectX 10 class graphics card.
* DirectX backend doesn't keep backup of all sprites in RAM anymore.
* Added high quality texture compression to reduce amount of video memory consumed by the game and increase overall rendering performance.
* Added texture streaming so that adding more sprites does not necessarily increase GPU requirements.
* Improved game startup performance when using a large amount of technologies with deep dependency trees (it's now 67,000 times faster).
* Optimized rendering of logistic overlay when zoomed in to map. ([https://forums.factorio.com/60659 more])
* Optimized rendering of turret ranges when zoomed in to map. ([https://forums.factorio.com/58991 more])
=== Changes ===
* Resource generation changed significantly:
** The starting area contains only iron, copper, coal and stone, in very predictable amounts. Uranium and oil are excluded from the starting area.
** Resource generation settings now have a much more dramatic effect. Increased the number of steps for each setting.
** Ore patches are slightly less frequent but richer.
** There will be a more balanced amount of resources within a large enough region.
** Many other small tweaks.
* Biter generation changed significantly:
** Biter richness slider removed, biter placement is only configured by size and frequency settings.
** Biter generation settings now have a much more dramatic effect. Increased the number of steps for each setting.
** Biter bases will increase in size, frequency and number of worms depending on the distance from player spawn.
** Worm size increases depending on the distance from player spawn.
** Small biter bases are now closer to the player spawn.
** At large distances from player spawn, biter base frequency is lower than before but biter bases are larger.
** Other small tweaks.
* Terrain generation changed significantly:
** Water is generated as large lakes instead of swamps.
** Tile generation improved. Tile placement respects biomes better.
** More predictable cliff placement.
** Better controls in the map generator GUI for water, tiles and cliffs.
* New map terrain type selectable: Island. Launch the rocket with only a limited amount of resources available on the map.
* Default resolution of the game is now 1920x1080.
* Increased player reach from 6 to 10.
* Inserters are putting science packs to the lab even when there is no research in progress or when the research doesn't need that particular pack.
* Default_request_amount removed in all places where it was used. Default logistic request is 1 stack, unless changed by the setting "Default request is 1".
* All personal equipment stack sizes changed to 20.
* Placing a tile will now clear any tile ghosts at that position. ([https://forums.factorio.com/59721 more])
* It is allowed to use unicode characters in save names.
* Recipes that have more ingredients than the assembling machine allows are now shown as red instead of not present when selecting the recipe.
* When the "Made in" row is shown in the recipe tooltip, player icon is added to the list when it is craftable by player.
* Increased ghost time to live of ghosts from 1 hour to 1 week.
* Since the catalysts have been tweaked, the kovarex enrichment process can now be used together with productivity module.
* Tile construction jobs are being handled by robots separately from entity building jobs, to prevent entity ghosts not being built due to large number of tile ghosts.
* Switched key bindings from key codes to scan codes. This solves an issue with bad default key bindings on layouts that are not similar to US QWERTY (ie. AZERTY).
* Armor no longer uses durability and all armor now has a stack size of 1.
* Manually putting modules into machines that are requesting modules from the logistic network will reduce the modules requested.
* Increased maximum train stop length from 50 to 100 characters so it can fit at least 3 tags in most cases.
* Items consumed by hand crafting are counted in item production statistics.
* Added --disable-migration-window command-line option to disable the "migrated content" gui.
* Removed tile properties debug overlay.
* Command-line map preview generator now shows biter nests.
* Items sent in a rocket are counted in item production statistics. ([https://forums.factorio.com/62606 more])
* Removed pickaxes and replaced them with research effects.
* Removed Wood from the game (And raw wood renamed to Wood).
* Added rotation smoothing to biters.
* Chests and wooden power poles are no longer usable as fuel.
* Burner efficiency is set to 100% for all entities and fuel value is halved to simplify calculations. This should not change game balance.
* Removed the hardness/mining power mechanics, we just have a mining speed and mining time now.
* Manual mining speed times of various entities will differ a bit, but probably not in a noticeable way.
* Stone and other ore mining speed has been unified to be 1 (apart uranium ore, which is 2 and shown as 200% mining time)
* Mining drill speed is now shown in the form of <x>/s (0.25/s for burner mining drill, 0.5/s for electric mining drill), the relative mining speeds of the mining machines have been decreased a little so the numbers are rounded nicely (0.28 -> 0.25 and 0.525 -> 0.5).
* Renamed the whitelist and banlist to server-whitelist and server-banlist.
* Added server-adminlist that's used to determine which people are admins when hosting any multiplayer game. This is synced both ways when hosting any game.
* Removed "admins" from the multiplayer server-settings file - they're now handled through server-adminlist.
* "Z" (drop item) will drop single items into what ever entity is selected instead of only dropping on the ground.
* Stickers can by applied onto cars and tanks now.
* Changed the chat gray-out mechanism. It always greyed-out after 5 seconds to 70% alpha, and then stayed depending on the setting. Now it stays 100% and only greys out away in the last 2 seconds.
* Placing entities or paths removes tree stumps and biter corpses.
* Removed New Hope campaign.

== 0.17.0 ==
Date: 26. 02. 2019
=== Major Features ===
* New quickbar (more in Gui section)
* Added shortcut bar that allows quick access to certain game features, such as toggling alt mode, creating blueprints, or turning off personal roboport
* New gui style with final version of some parts of the GUI (More in Gui section)
* Added clipboard functionality. (Control + C, Control + X, Control + V activate appropriate tools) Shift + mouse wheel allows to cycle the clipboard history.
* Added undo functionality (Control + Z). Supports manual entity building and by blueprints and manual mining and usage of deconstruction planner.
* Reworked the Map Editor so it's now part of the standard game and can be toggled at will using the '/editor' command.
* Support for mod synchronisation when joining multiplayer game. Works as long as the used mods are on the mod portal.
* Fight changes. Enemy projectiles are dodgeable and slowdown/damage the target over time. They also leave splashes on ground that have the same effect.
* Rich text tags. These tags can be used almost anywhere: Chat, station names, save names, custom ui and probably a few places we didn't think of.
** They allow changing color, font, images and location/blueprint/armor/station/locomotive linking through chat. (More in features)
* Fluid mixing prevention. Actions that fail as they would lead to fluid mixing (like building a pipe, changing recipe, rotating etc.) produce an error message as flying text.
* Replaced First steps campaign with Introduction campaign, available from the Start campaign menu.
=== Features ===
* Trains can be blueprinted and deconstructed.
* Trains can be given temporary stations (by Control+clicking the map). Temporary station is automatically removed once the train departures from it.
* Train stops without conditions work as waypoints. (the train doesn't stop at those)
* Added Passenger present and Passenger not present wait condition to the train conditions.
* If building of entity/blueprint fails, the reason of it is pinged as flying text.
* Map pings. Ctrl+Alt+click on the map to show a ping in all players maps at that location.
* Basic image tags format is [img=<image path>] where image path can use item, entity, technology, recipe, item-group, fluid tile, virtual signal achievement or utility icon.
** For example [img=item/iron-plate] or [img=item.iron-plate]. The "." instead of "/" usage is to make it usable in save names.
** Additionally, items/entities/technologies/recipe/item-group/fluid/tile/virtual signal or achievement can be linked directly by [item=iron-plate], [recipe=iron-plate], or [entity=small-biter] to provide tooltip for the appropriate object.
* Blueprint/special item tags.
** Shift clicking the icon in chat will create an item and place it in the cursor.
** Format is [special-item=blueprint string], eg: [special-item=0eNp1jtEKwjAMRX9l5rnCxkShvyIi3YxboU1Lm4lj9N9N54sv5iFwL/eeZIPBLRiTJQa9gR0DZdDXDbKdyLjq8RoRNFhGDwrI+Ko4GcoxJD4O6BiKAksPfIPuyk0BElu2+CXtYr3T4gdMEvjHUBBDllqgelVQrYJVdqnE/br+eVaBM1ITb0bnQvNMwTc8YzPOhiZ0YTpI5oUp78BL33YnmbY/l/IBb4pSQQ==].
** These tags also work with deconstruction and upgrade planners.
* Map ping tags: Created by shift-clicking the ground/map when the chat is open. Format is [gps=x,y], eg [gps=10,30] will show a map ping in all players maps at location 10,30.
** Clicking the icon in chat will open the map on the specified location.
* Font tags: Format is [font=debug-mono]mono text[/font].
* Color tags: Format is [color=1,0,0]red text[/font]
* Fast replacing pipes by pipes to ground similar to underground belts.
* When multiple versions of the same mod are installed you can select which version you want to use.
* The sync mods with save/multiplayer game feature can now sync mod startup settings as well as mods.
* Added support to import and export permissions.
* Closing opened items (blueprint books/armor) now remembers what GUI you previously had open.
* Filter inserters can be set to whitelist or blacklist filters.
* Added belt immunity equipment.
* Added upgrade planner.
* Added steam networking support for steam users.
* Added RGB support for Logitech hardware.
* Robots can blow up cliffs.
* Wave defense scenario has been reworked to support multiple rounds and a procedurally generated map.
* Added a research queue that becomes available after the player has finished the game by launching a rocket with satellite.
=== Minor Features ===
* Warning icon for automated trains that are out of fuel.
* Added 250 and 1000 hours precision intervals into statistics.
* Using deconstruction planner is incorporated in the latency hiding.
* Changed personal roboports so they won't send construction robots if you're driving in a vehicle that they can't keep up with or if in a train in automatic mode.
* Added an option to ignore mouse events when using accessibility zoom feature on macOS.
* Added support to change multiplayer config settings runtime.
* Added support to edit the whitelist, banlist, and admin list when hosting a multiplayer game.
* Added the Admin GUI (openable through /admin in the console) to manage multiplayer players.
* Landfill can be built by robots and be included in blueprints.
* Blueprint items taken from blueprint library will not move to player inventory when Q is pressed, but can be moved to any slot explicitly. (Same as with clipboard items)
* When selecting any item to the cursor from some of the player inventories. As long as the item is being held, hand icon is shown on the slot it was taken from. The hand prevents any other item to be inserted into the slot as long as the player cursor isn't cleared.
* When holding radar in cursor, area covered by existing radars is also highlighted on minimap.
* Configurable (in gui), the count of rolling stocks shown in the train visualization.
* Added two levels of shallow water tiles (only placed by map editor, not generated). Enemies and vehicles can travel over shallow water.
=== Graphics ===
* New graphics for:
** accumulator
** biters, spitters, worms, spawners
** chests
** electric poles and substation
** map edge transitions
** rocket silo
** transport belts, underground belts, splitters and transport belt circuit connector
** trees
** turrets (gun, flamethrower and laser)
** walls and gates
* laser turrets, personal laser defense and distractor robots now use new laser beams.
* Highlighting inserters that would interact with selected/previewed entity.
* Showing shield bars above health bar for relevant entities.
* Single vertical pipe is shorter.
=== Gui ===
* New final versions of several important GUI screens (Quick bar, Train Schedule, Load/Save Game, Settings, Map Generator, Research, Mods)
** Other screens than the mentioned ones (more than 100) have inconsistencies and will be updated in future minor updates.
* The quickbar is no longer an inventory, instead it can only hold shortcuts it items in inventory or blueprint library.
** The quickbar now has 10 pages of shortcuts.
** Player inventory increased by 20 slots to compensate. Toolbelt research further increases the player inventory.
* In the map, station and tag selection is now visualized by the standard Factorio selection box graphics instead of highlighting.
* Added interface option: When selecting a buildable item from the quickbar or when using the pipette tool, if you have no items of that type, a ghost will be placed in the cursor instead.
* When something is not buildable (manual or blueprint building), the reason of why it isn't buildable is shown as flying text over the cursor when the build is attempted.
* Only compatible results of a furnace are manually placeable in the result slot. (Mainly to avoid confusion of new players)
=== Optimisations ===
* Modernized and optimized rendering backend. The game now uses DirectX 11 or OpenGL 3.3 Core and requires DirectX 10 class graphics card.
* DirectX backend doesn't keep backup of all sprites in RAM anymore.
* Added high quality texture compression to reduce amount of video memory consumed by the game and increase overall rendering performance.
* Added texture streaming so that adding more sprites does not necessarily increase GPU requirements.
* Improved game startup performance when using a large amount of technologies with deep dependency trees (it's now 67,000 times faster).
* Optimized rendering of logistic overlay when zoomed in to map. ([https://forums.factorio.com/60659 more])
* Optimized rendering of turret ranges when zoomed in to map. ([https://forums.factorio.com/58991 more])
=== Changes ===
* Resource generation changed significantly:
** The starting area contains only iron, copper, coal and stone, in very predictable amounts. Uranium and oil are excluded from the starting area.
** Resource generation settings now have a much more dramatic effect. Increased the number of steps for each setting.
** Ore patches are slightly less frequent but richer.
** There will be a more balanced amount of resources within a large enough region.
** Many other small tweaks.
* Biter generation changed significantly:

** Biter bases will increase in size, frequency and number of worms depending on the distance from player spawn.
** Worm size increases depending on the distance from player spawn.
** Small biter bases are now closer to the player spawn.
** At large distances from player spawn, biter base frequency is lower than before but biter bases are larger.
** Other small tweaks.

** Water is generated as large lakes instead of swamps.
** Tile generation improved. Tile placement respects biomes better.
** More predictable cliff placement.
** Better controls in the map generator GUI for water, tiles and cliffs.
* New map terrain type selectable: Island. Launch the rocket with only a limited amount of resources available on the map.
* Default resolution of the game is now 1920x1080.
* Increased player reach from 6 to 10.

* Tile construction jobs are being handled by robots separately from entity building jobs, to prevent entity ghosts not being built due to large number of tile ghosts.
* Switched key bindings from key codes to scan codes. This solves an issue with bad default key bindings on layouts that are not similar to US QWERTY (ie. AZERTY).
* Armor no longer uses durability and all armor now has a stack size of 1.
* Manually putting modules into machines that are requesting modules from the logistic network will reduce the modules requested.
* Increased maximum train stop length from 50 to 100 characters so it can fit at least 3 tags in most cases.

* Added rotation smoothing to biters.
* Chests and wooden power poles are no longer usable as fuel.
* Burner efficiency is set to 100% for all entities and fuel value is halved to simplify calculations. This should not change game balance.
* Removed the hardness/mining power mechanics, we just have a mining speed and mining time now.
* Manual mining speed times of various entities will differ a bit, but probably not in a noticeable way.
* Stone and other ore mining speed has been unified to be 1 (apart uranium ore, which is 2 and shown as 200% mining time)
* Mining drill speed is now shown in the form of <x>/s (0.25/s for burner mining drill, 0.5/s for electric mining drill), the relative mining speeds of the mining machines have been decreased a little so the numbers are rounded nicely (0.28 -> 0.25 and 0.525 -> 0.5).
* Renamed the whitelist and banlist to server-whitelist and server-banlist.
* Added server-adminlist that's used to determine which people are admins when hosting any multiplayer game. This is synced both ways when hosting any game.
* Removed "admins" from the multiplayer server-settings file - they're now handled through server-adminlist.
* "Z" (drop item) will drop single items into what ever entity is selected instead of only dropping on the ground.
* Stickers can by applied onto cars and tanks now.
* Changed the chat gray-out mechanism. It always greyed-out after 5 seconds to 70% alpha, and then stayed depending on the setting. Now it stays 100% and only greys out away in the last 2 seconds.
* Placing entities or paths removes tree stumps and biter corpses.
* Removed New Hope campaign.

== 0.17.0 ==
Date: 26. 02. 2019
=== Major Features ===
* New quickbar (more in Gui section)
* Added shortcut bar that allows quick access to certain game features, such as toggling alt mode, creating blueprints, or turning off personal roboport
* New gui style with final version of some parts of the GUI (More in Gui section)
* Added clipboard functionality. (Control + C, Control + X, Control + V activate appropriate tools) Shift + mouse wheel allows to cycle the clipboard history.
* Added undo functionality (Control + Z). Supports manual entity building and by blueprints and manual mining and usage of deconstruction planner.
* Reworked the Map Editor so it's now part of the standard game and can be toggled at will using the '/editor' command.
* Support for mod synchronisation when joining multiplayer game. Works as long as the used mods are on the mod portal.
* Fight changes. Enemy projectiles are dodgeable and slowdown/damage the target over time. They also leave splashes on ground that have the same effect.
* Rich text tags. These tags can be used almost anywhere: Chat, station names, save names, custom ui and probably a few places we didn't think of.
** They allow changing color, font, images and location/blueprint/armor/station/locomotive linking through chat. (More in features)
* Fluid mixing prevention. Actions that fail as they would lead to fluid mixing (like building a pipe, changing recipe, rotating etc.) produce an error message as flying text.
* Replaced First steps campaign with Introduction campaign, available from the Start campaign menu.
=== Features ===
* Trains can be blueprinted and deconstructed.
* Trains can be given temporary stations (by Control+clicking the map). Temporary station is automatically removed once the train departures from it.
* Train stops without conditions work as waypoints. (the train doesn't stop at those)
* Added Passenger present and Passenger not present wait condition to the train conditions.
* If building of entity/blueprint fails, the reason of it is pinged as flying text.
* Map pings. Ctrl+Alt+click on the map to show a ping in all players maps at that location.
* Basic image tags format is [img=<image path>] where image path can use item, entity, technology, recipe, item-group, fluid tile, virtual signal achievement or utility icon.
** For example [img=item/iron-plate] or [img=item.iron-plate]. The "." instead of "/" usage is to make it usable in save names.
** Additionally, items/entities/technologies/recipe/item-group/fluid/tile/virtual signal or achievement can be linked directly by [item=iron-plate], [recipe=iron-plate], or [entity=small-biter] to provide tooltip for the appropriate object.
* Blueprint/special item tags.
** Shift clicking the icon in chat will create an item and place it in the cursor.
** Format is [special-item=blueprint string], eg: [special-item=0eNp1jtEKwjAMRX9l5rnCxkShvyIi3YxboU1Lm4lj9N9N54sv5iFwL/eeZIPBLRiTJQa9gR0DZdDXDbKdyLjq8RoRNFhGDwrI+Ko4GcoxJD4O6BiKAksPfIPuyk0BElu2+CXtYr3T4gdMEvjHUBBDllqgelVQrYJVdqnE/br+eVaBM1ITb0bnQvNMwTc8YzPOhiZ0YTpI5oUp78BL33YnmbY/l/IBb4pSQQ==].
** These tags also work with deconstruction and upgrade planners.
* Map ping tags: Created by shift-clicking the ground/map when the chat is open. Format is [gps=x,y], eg [gps=10,30] will show a map ping in all players maps at location 10,30.
** Clicking the icon in chat will open the map on the specified location.
* Font tags: Format is [font=debug-mono]mono text[/font].
* Color tags: Format is [color=1,0,0]red text[/font]
* Fast replacing pipes by pipes to ground similar to underground belts.
* When multiple versions of the same mod are installed you can select which version you want to use.
* The sync mods with save/multiplayer game feature can now sync mod startup settings as well as mods.
* Added support to import and export permissions.
* Closing opened items (blueprint books/armor) now remembers what GUI you previously had open.
* Filter inserters can be set to whitelist or blacklist filters.
* Added belt immunity equipment.
* Added upgrade planner.
* Added steam networking support for steam users.
* Added RGB support for Logitech hardware.
* Robots can blow up cliffs.
* Wave defense scenario has been reworked to support multiple rounds and a procedurally generated map.
* Added a research queue that becomes available after the player has finished the game by launching a rocket with satellite.
=== Minor Features ===
* Warning icon for automated trains that are out of fuel.
* Added 250 and 1000 hours precision intervals into statistics.
* Using deconstruction planner is incorporated in the latency hiding.
* Changed personal roboports so they won't send construction robots if you're driving in a vehicle that they can't keep up with or if in a train in automatic mode.
* Added an option to ignore mouse events when using accessibility zoom feature on macOS.
* Added support to change multiplayer config settings runtime.
* Added support to edit the whitelist, banlist, and admin list when hosting a multiplayer game.
* Added the Admin GUI (openable through /admin in the console) to manage multiplayer players.
* Landfill can be built by robots and be included in blueprints.
* Blueprint items taken from blueprint library will not move to player inventory when Q is pressed, but can be moved to any slot explicitly. (Same as with clipboard items)
* When selecting any item to the cursor from some of the player inventories. As long as the item is being held, hand icon is shown on the slot it was taken from. The hand prevents any other item to be inserted into the slot as long as the player cursor isn't cleared.
* When holding radar in cursor, area covered by existing radars is also highlighted on minimap.
* Configurable (in gui), the count of rolling stocks shown in the train visualization.
* Added two levels of shallow water tiles (only placed by map editor, not generated). Enemies and vehicles can travel over shallow water.
=== Graphics ===
* New graphics for:
** accumulator
** biters, spitters, worms, spawners
** chests
** electric poles and substation
** map edge transitions
** rocket silo
** transport belts, underground belts, splitters and transport belt circuit connector
** trees
** turrets (gun, flamethrower and laser)
** walls and gates
* laser turrets, personal laser defense and distractor robots now use new laser beams.
* Highlighting inserters that would interact with selected/previewed entity.
* Showing shield bars above health bar for relevant entities.
* Single vertical pipe is shorter.
=== Gui ===
* New final versions of several important GUI screens (Quick bar, Train Schedule, Load/Save Game, Settings, Map Generator, Research, Mods)
** Other screens than the mentioned ones (more than 100) have inconsistencies and will be updated in future minor updates.
* The quickbar is no longer an inventory, instead it can only hold shortcuts it items in inventory or blueprint library.
** The quickbar now has 10 pages of shortcuts.
** Player inventory increased by 20 slots to compensate. Toolbelt research further increases the player inventory.
* In the map, station and tag selection is now visualized by the standard Factorio selection box graphics instead of highlighting.
* Added interface option: When selecting a buildable item from the quickbar or when using the pipette tool, if you have no items of that type, a ghost will be placed in the cursor instead.
* When something is not buildable (manual or blueprint building), the reason of why it isn't buildable is shown as flying text over the cursor when the build is attempted.
* Only compatible results of a furnace are manually placeable in the result slot. (Mainly to avoid confusion of new players)
=== Optimisations ===
* Modernized and optimized rendering backend. The game now uses DirectX 11 or OpenGL 3.3 Core and requires DirectX 10 class graphics card.
* DirectX backend doesn't keep backup of all sprites in RAM anymore.
* Added high quality texture compression to reduce amount of video memory consumed by the game and increase overall rendering performance.
* Added texture streaming so that adding more sprites does not necessarily increase GPU requirements.
* Improved game startup performance when using a large amount of technologies with deep dependency trees (it's now 67,000 times faster).
* Optimized rendering of logistic overlay when zoomed in to map. ([https://forums.factorio.com/60659 more])
* Optimized rendering of turret ranges when zoomed in to map. ([https://forums.factorio.com/58991 more])
=== Changes ===
* Resource generation changed significantly:
** The starting area contains only iron, copper, coal and stone, in very predictable amounts. Uranium and oil are excluded from the starting area.
** Resource generation settings now have a much more dramatic effect. Increased the number of steps for each setting.
** Ore patches are slightly less frequent but richer.
** There will be a more balanced amount of resources within a large enough region.
** Many other small tweaks.
* Biter generation changed significantly:
** Biter richness slider removed, biter placement is only configured by size and frequency settings.
** Biter generation settings now have a much more dramatic effect. Increased the number of steps for each setting.
** Biter bases will increase in size, frequency and number of worms depending on the distance from player spawn.
** Worm size increases depending on the distance from player spawn.
** Small biter bases are now closer to the player spawn.
** At large distances from player spawn, biter base frequency is lower than before but biter bases are larger.
** Other small tweaks.
* Terrain generation changed significantly:
** Water is generated as large lakes instead of swamps.
** Tile generation improved. Tile placement respects biomes better.
** More predictable cliff placement.
** Better controls in the map generator GUI for water, tiles and cliffs.
* New map terrain type selectable: Island. Launch the rocket with only a limited amount of resources available on the map.
* Default resolution of the game is now 1920x1080.
* Increased player reach from 6 to 10.
* Inserters are putting science packs to the lab even when there is no research in progress or when the research doesn't need that particular pack.
* Default_request_amount removed in all places where it was used. Default logistic request is 1 stack, unless changed by the setting "Default request is 1".
* All personal equipment stack sizes changed to 20.
* Placing a tile will now clear any tile ghosts at that position. ([https://forums.factorio.com/59721 more])
* It is allowed to use unicode characters in save names.
* Recipes that have more ingredients than the assembling machine allows are now shown as red instead of not present when selecting the recipe.
* When the "Made in" row is shown in the recipe tooltip, player icon is added to the list when it is craftable by player.
* Increased ghost time to live of ghosts from 1 hour to 1 week.
* Since the catalysts have been tweaked, the kovarex enrichment process can now be used together with productivity module.
* Tile construction jobs are being handled by robots separately from entity building jobs, to prevent entity ghosts not being built due to large number of tile ghosts.
* Switched key bindings from key codes to scan codes. This solves an issue with bad default key bindings on layouts that are not similar to US QWERTY (ie. AZERTY).
* Armor no longer uses durability and all armor now has a stack size of 1.
* Manually putting modules into machines that are requesting modules from the logistic network will reduce the modules requested.
* Increased maximum train stop length from 50 to 100 characters so it can fit at least 3 tags in most cases.
* Items consumed by hand crafting are counted in item production statistics.

== 0.17.0 ==
Date: 26. 02. 2019
=== Major Features ===
* New quickbar (more in Gui section)
* Added shortcut bar that allows quick access to certain game features, such as toggling alt mode, creating blueprints, or turning off personal roboport
* New gui style with final version of some parts of the GUI (More in Gui section)
* Added clipboard functionality. (Control + C, Control + X, Control + V activate appropriate tools) Shift + mouse wheel allows to cycle the clipboard history.
* Added undo functionality (Control + Z). Supports manual entity building and by blueprints and manual mining and usage of deconstruction planner.
* Reworked the Map Editor so it's now part of the standard game and can be toggled at will using the '/editor' command.
* Support for mod synchronisation when joining multiplayer game. Works as long as the used mods are on the mod portal.
* Fight changes. Enemy projectiles are dodgeable and slowdown/damage the target over time. They also leave splashes on ground that have the same effect.
* Rich text tags. These tags can be used almost anywhere: Chat, station names, save names, custom ui and probably a few places we didn't think of.
** They allow changing color, font, images and location/blueprint/armor/station/locomotive linking through chat. (More in features)
* Fluid mixing prevention. Actions that fail as they would lead to fluid mixing (like building a pipe, changing recipe, rotating etc.) produce an error message as flying text.
* Replaced First steps campaign with Introduction campaign, available from the Start campaign menu.
=== Features ===
* Trains can be blueprinted and deconstructed.
* Trains can be given temporary stations (by Control+clicking the map). Temporary station is automatically removed once the train departures from it.
* Train stops without conditions work as waypoints. (the train doesn't stop at those)
* Added Passenger present and Passenger not present wait condition to the train conditions.
* If building of entity/blueprint fails, the reason of it is pinged as flying text.
* Map pings. Ctrl+Alt+click on the map to show a ping in all players maps at that location.
* Basic image tags format is [img=<image path>] where image path can use item, entity, technology, recipe, item-group, fluid tile, virtual signal achievement or utility icon.
** For example [img=item/iron-plate] or [img=item.iron-plate]. The "." instead of "/" usage is to make it usable in save names.
** Additionally, items/entities/technologies/recipe/item-group/fluid/tile/virtual signal or achievement can be linked directly by [item=iron-plate], [recipe=iron-plate], or [entity=small-biter] to provide tooltip for the appropriate object.
* Blueprint/special item tags.
** Shift clicking the icon in chat will create an item and place it in the cursor.
** Format is [special-item=blueprint string], eg: [special-item=0eNp1jtEKwjAMRX9l5rnCxkShvyIi3YxboU1Lm4lj9N9N54sv5iFwL/eeZIPBLRiTJQa9gR0DZdDXDbKdyLjq8RoRNFhGDwrI+Ko4GcoxJD4O6BiKAksPfIPuyk0BElu2+CXtYr3T4gdMEvjHUBBDllqgelVQrYJVdqnE/br+eVaBM1ITb0bnQvNMwTc8YzPOhiZ0YTpI5oUp78BL33YnmbY/l/IBb4pSQQ==].
** These tags also work with deconstruction and upgrade planners.
* Map ping tags: Created by shift-clicking the ground/map when the chat is open. Format is [gps=x,y], eg [gps=10,30] will show a map ping in all players maps at location 10,30.
** Clicking the icon in chat will open the map on the specified location.
* Font tags: Format is [font=debug-mono]mono text[/font].
* Color tags: Format is [color=1,0,0]red text[/font]
* Fast replacing pipes by pipes to ground similar to underground belts.
* When multiple versions of the same mod are installed you can select which version you want to use.
* The sync mods with save/multiplayer game feature can now sync mod startup settings as well as mods.
* Added support to import and export permissions.
* Closing opened items (blueprint books/armor) now remembers what GUI you previously had open.
* Filter inserters can be set to whitelist or blacklist filters.
* Added belt immunity equipment.
* Added upgrade planner.
* Added steam networking support for steam users.
* Added RGB support for Logitech hardware.
* Robots can blow up cliffs.
* Wave defense scenario has been reworked to support multiple rounds and a procedurally generated map.
* Added a research queue that becomes available after the player has finished the game by launching a rocket with satellite.
=== Minor Features ===
* Warning icon for automated trains that are out of fuel.
* Added 250 and 1000 hours precision intervals into statistics.
* Using deconstruction planner is incorporated in the latency hiding.

* Blueprint items taken from blueprint library will not move to player inventory when Q is pressed, but can be moved to any slot explicitly. (Same as with clipboard items)
* When selecting any item to the cursor from some of the player inventories. As long as the item is being held, hand icon is shown on the slot it was taken from. The hand prevents any other item to be inserted into the slot as long as the player cursor isn't cleared.
* When holding radar in cursor, area covered by existing radars is also highlighted on minimap.
* Configurable (in gui), the count of rolling stocks shown in the train visualization.
* Added two levels of shallow water tiles (only placed by map editor, not generated). Enemies and vehicles can travel over shallow water.

* Highlighting inserters that would interact with selected/previewed entity.
* Showing shield bars above health bar for relevant entities.
* Single vertical pipe is shorter.
=== Gui ===
* New final versions of several important GUI screens (Quick bar, Train Schedule, Load/Save Game, Settings, Map Generator, Research, Mods)
** Other screens than the mentioned ones (more than 100) have inconsistencies and will be updated in future minor updates.
* The quickbar is no longer an inventory, instead it can only hold shortcuts it items in inventory or blueprint library.
** The quickbar now has 10 pages of shortcuts.
** Player inventory increased by 20 slots to compensate. Toolbelt research further increases the player inventory.
* In the map, station and tag selection is now visualized by the standard Factorio selection box graphics instead of highlighting.
* Added interface option: When selecting a buildable item from the quickbar or when using the pipette tool, if you have no items of that type, a ghost will be placed in the cursor instead.
* When something is not buildable (manual or blueprint building), the reason of why it isn't buildable is shown as flying text over the cursor when the build is attempted.
* Only compatible results of a furnace are manually placeable in the result slot. (Mainly to avoid confusion of new players)
=== Optimisations ===
* Modernized and optimized rendering backend. The game now uses DirectX 11 or OpenGL 3.3 Core and requires DirectX 10 class graphics card.
* DirectX backend doesn't keep backup of all sprites in RAM anymore.
* Added high quality texture compression to reduce amount of video memory consumed by the game and increase overall rendering performance.
* Added texture streaming so that adding more sprites does not necessarily increase GPU requirements.
* Improved game startup performance when using a large amount of technologies with deep dependency trees (it's now 67,000 times faster).
* Optimized rendering of logistic overlay when zoomed in to map. ([https://forums.factorio.com/60659 more])
* Optimized rendering of turret ranges when zoomed in to map. ([https://forums.factorio.com/58991 more])
=== Changes ===

** Resource generation settings now have a much more dramatic effect. Increased the number of steps for each setting.
** Ore patches are slightly less frequent but richer.
** There will be a more balanced amount of resources within a large enough region.
** Many other small tweaks.

** Biter bases will increase in size, frequency and number of worms depending on the distance from player spawn.
** Worm size increases depending on the distance from player spawn.
** Small biter bases are now closer to the player spawn.
** At large distances from player spawn, biter base frequency is lower than before but biter bases are larger.
** Other small tweaks.
* Terrain generation changed significantly:
** Water is generated as large lakes instead of swamps.
** Tile generation improved. Tile placement respects biomes better.
** More predictable cliff placement.
** Better controls in the map generator GUI for water, tiles and cliffs.

* When the "Made in" row is shown in the recipe tooltip, player icon is added to the list when it is craftable by player.
* Increased ghost time to live of ghosts from 1 hour to 1 week.
* Since the catalysts have been tweaked, the kovarex enrichment process can now be used together with productivity module.
* Tile construction jobs are being handled by robots separately from entity building jobs, to prevent entity ghosts not being built due to large number of tile ghosts.
* Switched key bindings from key codes to scan codes. This solves an issue with bad default key bindings on layouts that are not similar to US QWERTY (ie. AZERTY).
* Armor no longer uses durability and all armor now has a stack size of 1.
* Manually putting modules into machines that are requesting modules from the logistic network will reduce the modules requested.
* Increased maximum train stop length from 50 to 100 characters so it can fit at least 3 tags in most cases.
* Items consumed by hand crafting are counted in item production statistics.
* Added --disable-migration-window command-line option to disable the "migrated content" gui.
* Removed tile properties debug overlay.

* Removed Wood from the game (And raw wood renamed to Wood).
* Added rotation smoothing to biters.
* Chests and wooden power poles are no longer usable as fuel.
* Burner efficiency is set to 100% for all entities and fuel value is halved to simplify calculations. This should not change game balance.
* Removed the hardness/mining power mechanics, we just have a mining speed and mining time now.
* Manual mining speed times of various entities will differ a bit, but probably not in a noticeable way.
* Stone and other ore mining speed has been unified to be 1 (apart uranium ore, which is 2 and shown as 200% mining time)
* Mining drill speed is now shown in the form of <x>/s (0.25/s for burner mining drill, 0.5/s for electric mining drill), the relative mining speeds of the mining machines have been decreased a little so the numbers are rounded nicely (0.28 -> 0.25 and 0.525 -> 0.5).
* Renamed the whitelist and banlist to server-whitelist and server-banlist.
* Added server-adminlist that's used to determine which people are admins when hosting any multiplayer game. This is synced both ways when hosting any game.
* Removed "admins" from the multiplayer server-settings file - they're now handled through server-adminlist.
* "Z" (drop item) will drop single items into what ever entity is selected instead of only dropping on the ground.
* Stickers can by applied onto cars and tanks now.
* Changed the chat gray-out mechanism. It always greyed-out after 5 seconds to 70% alpha, and then stayed depending on the setting. Now it stays 100% and only greys out away in the last 2 seconds.
* Placing entities or paths removes tree stumps and biter corpses.
* Removed New Hope campaign.

* New gui style with final version of some parts of the GUI (More in Gui section)
* Added clipboard functionality. (Control + C, Control + X, Control + V activate appropriate tools) Shift + mouse wheel allows to cycle the clipboard history.
* Added undo functionality (Control + Z). Supports manual entity building and by blueprints and manual mining and usage of deconstruction planner.
* Reworked the Map Editor so it's now part of the standard game and can be toggled at will using the '/editor' command.
* Support for mod synchronisation when joining multiplayer game. Works as long as the used mods are on the mod portal.
* Fight changes. Enemy projectiles are dodgeable and slowdown/damage the target over time. They also leave splashes on ground that have the same effect.
* Rich text tags. These tags can be used almost anywhere: Chat, station names, save names, custom ui and probably a few places we didn't think of.
** They allow changing color, font, images and location/blueprint/armor/station/locomotive linking through chat. (More in features)
* Fluid mixing prevention. Actions that fail as they would lead to fluid mixing (like building a pipe, changing recipe, rotating etc.) produce an error message as flying text.
* Replaced First steps campaign with Introduction campaign, available from the Start campaign menu.
=== Features ===
* Trains can be blueprinted and deconstructed.
* Trains can be given temporary stations (by Control+clicking the map). Temporary station is automatically removed once the train departures from it.
* Train stops without conditions work as waypoints. (the train doesn't stop at those)
* Added Passenger present and Passenger not present wait condition to the train conditions.
* If building of entity/blueprint fails, the reason of it is pinged as flying text.
* Map pings. Ctrl+Alt+click on the map to show a ping in all players maps at that location.
* Basic image tags format is [img=<image path>] where image path can use item, entity, technology, recipe, item-group, fluid tile, virtual signal achievement or utility icon.
** For example [img=item/iron-plate] or [img=item.iron-plate]. The "." instead of "/" usage is to make it usable in save names.
** Additionally, items/entities/technologies/recipe/item-group/fluid/tile/virtual signal or achievement can be linked directly by [item=iron-plate], [recipe=iron-plate], or [entity=small-biter] to provide tooltip for the appropriate object.
* Blueprint/special item tags.
** Shift clicking the icon in chat will create an item and place it in the cursor.
** Format is [special-item=blueprint string], eg: [special-item=0eNp1jtEKwjAMRX9l5rnCxkShvyIi3YxboU1Lm4lj9N9N54sv5iFwL/eeZIPBLRiTJQa9gR0DZdDXDbKdyLjq8RoRNFhGDwrI+Ko4GcoxJD4O6BiKAksPfIPuyk0BElu2+CXtYr3T4gdMEvjHUBBDllqgelVQrYJVdqnE/br+eVaBM1ITb0bnQvNMwTc8YzPOhiZ0YTpI5oUp78BL33YnmbY/l/IBb4pSQQ==].
** These tags also work with deconstruction and upgrade planners.
* Map ping tags: Created by shift-clicking the ground/map when the chat is open. Format is [gps=x,y], eg [gps=10,30] will show a map ping in all players maps at location 10,30.
** Clicking the icon in chat will open the map on the specified location.
* Font tags: Format is [font=debug-mono]mono text[/font].
* Color tags: Format is [color=1,0,0]red text[/font]
* Fast replacing pipes by pipes to ground similar to underground belts.
* When multiple versions of the same mod are installed you can select which version you want to use.
* The sync mods with save/multiplayer game feature can now sync mod startup settings as well as mods.
* Added support to import and export permissions.
* Closing opened items (blueprint books/armor) now remembers what GUI you previously had open.
* Filter inserters can be set to whitelist or blacklist filters.
* Added belt immunity equipment.
* Added upgrade planner.
* Added steam networking support for steam users.
* Added RGB support for Logitech hardware.
* Robots can blow up cliffs.
* Wave defense scenario has been reworked to support multiple rounds and a procedurally generated map.
* Added a research queue that becomes available after the player has finished the game by launching a rocket with satellite.
=== Minor Features ===
* Warning icon for automated trains that are out of fuel.
* Added 250 and 1000 hours precision intervals into statistics.
* Using deconstruction planner is incorporated in the latency hiding.
* Changed personal roboports so they won't send construction robots if you're driving in a vehicle that they can't keep up with or if in a train in automatic mode.
* Added an option to ignore mouse events when using accessibility zoom feature on macOS.
* Added support to change multiplayer config settings runtime.
* Added support to edit the whitelist, banlist, and admin list when hosting a multiplayer game.
* Added the Admin GUI (openable through /admin in the console) to manage multiplayer players.
* Landfill can be built by robots and be included in blueprints.
* Blueprint items taken from blueprint library will not move to player inventory when Q is pressed, but can be moved to any slot explicitly. (Same as with clipboard items)
* When selecting any item to the cursor from some of the player inventories. As long as the item is being held, hand icon is shown on the slot it was taken from. The hand prevents any other item to be inserted into the slot as long as the player cursor isn't cleared.
* When holding radar in cursor, area covered by existing radars is also highlighted on minimap.
* Configurable (in gui), the count of rolling stocks shown in the train visualization.
* Added two levels of shallow water tiles (only placed by map editor, not generated). Enemies and vehicles can travel over shallow water.
=== Graphics ===
* New graphics for:

** biters, spitters, worms, spawners
** chests
** electric poles and substation
** map edge transitions
** rocket silo
** transport belts, underground belts, splitters and transport belt circuit connector
** trees
** turrets (gun, flamethrower and laser)
** walls and gates
* laser turrets, personal laser defense and distractor robots now use new laser beams.
* Highlighting inserters that would interact with selected/previewed entity.
* Showing shield bars above health bar for relevant entities.
* Single vertical pipe is shorter.
=== Gui ===
* New final versions of several important GUI screens (Quick bar, Train Schedule, Load/Save Game, Settings, Map Generator, Research, Mods)
** Other screens than the mentioned ones (more than 100) have inconsistencies and will be updated in future minor updates.
* The quickbar is no longer an inventory, instead it can only hold shortcuts it items in inventory or blueprint library.
** The quickbar now has 10 pages of shortcuts.
** Player inventory increased by 20 slots to compensate. Toolbelt research further increases the player inventory.
* In the map, station and tag selection is now visualized by the standard Factorio selection box graphics instead of highlighting.
* Added interface option: When selecting a buildable item from the quickbar or when using the pipette tool, if you have no items of that type, a ghost will be placed in the cursor instead.
* When something is not buildable (manual or blueprint building), the reason of why it isn't buildable is shown as flying text over the cursor when the build is attempted.
* Only compatible results of a furnace are manually placeable in the result slot. (Mainly to avoid confusion of new players)
=== Optimisations ===
* Modernized and optimized rendering backend. The game now uses DirectX 11 or OpenGL 3.3 Core and requires DirectX 10 class graphics card.
* DirectX backend doesn't keep backup of all sprites in RAM anymore.
* Added high quality texture compression to reduce amount of video memory consumed by the game and increase overall rendering performance.
* Added texture streaming so that adding more sprites does not necessarily increase GPU requirements.
* Improved game startup performance when using a large amount of technologies with deep dependency trees (it's now 67,000 times faster).
* Optimized rendering of logistic overlay when zoomed in to map. ([https://forums.factorio.com/60659 more])
* Optimized rendering of turret ranges when zoomed in to map. ([https://forums.factorio.com/58991 more])
=== Changes ===

** Resource generation settings now have a much more dramatic effect. Increased the number of steps for each setting.
** Ore patches are slightly less frequent but richer.
** There will be a more balanced amount of resources within a large enough region.
** Many other small tweaks.
* Biter generation changed significantly:
** Biter richness slider removed, biter placement is only configured by size and frequency settings.
** Biter generation settings now have a much more dramatic effect. Increased the number of steps for each setting.
** Biter bases will increase in size, frequency and number of worms depending on the distance from player spawn.
** Worm size increases depending on the distance from player spawn.
** Small biter bases are now closer to the player spawn.
** At large distances from player spawn, biter base frequency is lower than before but biter bases are larger.
** Other small tweaks.
* Terrain generation changed significantly:
** Water is generated as large lakes instead of swamps.
** Tile generation improved. Tile placement respects biomes better.
** More predictable cliff placement.
** Better controls in the map generator GUI for water, tiles and cliffs.
* New map terrain type selectable: Island. Launch the rocket with only a limited amount of resources available on the map.
* Default resolution of the game is now 1920x1080.
* Increased player reach from 6 to 10.
* Inserters are putting science packs to the lab even when there is no research in progress or when the research doesn't need that particular pack.
* Default_request_amount removed in all places where it was used. Default logistic request is 1 stack, unless changed by the setting "Default request is 1".

* Placing a tile will now clear any tile ghosts at that position. ([https://forums.factorio.com/59721 more])
* It is allowed to use unicode characters in save names.
* Recipes that have more ingredients than the assembling machine allows are now shown as red instead of not present when selecting the recipe.
* When the "Made in" row is shown in the recipe tooltip, player icon is added to the list when it is craftable by player.
* Increased ghost time to live of ghosts from 1 hour to 1 week.
* Since the catalysts have been tweaked, the kovarex enrichment process can now be used together with productivity module.
* Tile construction jobs are being handled by robots separately from entity building jobs, to prevent entity ghosts not being built due to large number of tile ghosts.
* Switched key bindings from key codes to scan codes. This solves an issue with bad default key bindings on layouts that are not similar to US QWERTY (ie. AZERTY).
* Armor no longer uses durability and all armor now has a stack size of 1.
* Manually putting modules into machines that are requesting modules from the logistic network will reduce the modules requested.
* Increased maximum train stop length from 50 to 100 characters so it can fit at least 3 tags in most cases.
* Items consumed by hand crafting are counted in item production statistics.
* Added --disable-migration-window command-line option to disable the "migrated content" gui.
* Removed tile properties debug overlay.
* Command-line map preview generator now shows biter nests.

* Removed Wood from the game (And raw wood renamed to Wood).
* Added rotation smoothing to biters.
* Chests and wooden power poles are no longer usable as fuel.
* Burner efficiency is set to 100% for all entities and fuel value is halved to simplify calculations. This should not change game balance.
* Removed the hardness/mining power mechanics, we just have a mining speed and mining time now.
* Manual mining speed times of various entities will differ a bit, but probably not in a noticeable way.
* Stone and other ore mining speed has been unified to be 1 (apart uranium ore, which is 2 and shown as 200% mining time)
* Mining drill speed is now shown in the form of <x>/s (0.25/s for burner mining drill, 0.5/s for electric mining drill), the relative mining speeds of the mining machines have been decreased a little so the numbers are rounded nicely (0.28 -> 0.25 and 0.525 -> 0.5).
* Renamed the whitelist and banlist to server-whitelist and server-banlist.
* Added server-adminlist that's used to determine which people are admins when hosting any multiplayer game. This is synced both ways when hosting any game.
* Removed "admins" from the multiplayer server-settings file - they're now handled through server-adminlist.
* "Z" (drop item) will drop single items into what ever entity is selected instead of only dropping on the ground.
* Stickers can by applied onto cars and tanks now.
* Changed the chat gray-out mechanism. It always greyed-out after 5 seconds to 70% alpha, and then stayed depending on the setting. Now it stays 100% and only greys out away in the last 2 seconds.
* Placing entities or paths removes tree stumps and biter corpses.
* Removed New Hope campaign.

== 0.17.0 ==
Date: 26. 02. 2019
=== Major Features ===
* New quickbar (more in Gui section)
* Added shortcut bar that allows quick access to certain game features, such as toggling alt mode, creating blueprints, or turning off personal roboport
* New gui style with final version of some parts of the GUI (More in Gui section)
* Added clipboard functionality. (Control + C, Control + X, Control + V activate appropriate tools) Shift + mouse wheel allows to cycle the clipboard history.
* Added undo functionality (Control + Z). Supports manual entity building and by blueprints and manual mining and usage of deconstruction planner.
* Reworked the Map Editor so it's now part of the standard game and can be toggled at will using the '/editor' command.
* Support for mod synchronisation when joining multiplayer game. Works as long as the used mods are on the mod portal.
* Fight changes. Enemy projectiles are dodgeable and slowdown/damage the target over time. They also leave splashes on ground that have the same effect.
* Rich text tags. These tags can be used almost anywhere: Chat, station names, save names, custom ui and probably a few places we didn't think of.
** They allow changing color, font, images and location/blueprint/armor/station/locomotive linking through chat. (More in features)
* Fluid mixing prevention. Actions that fail as they would lead to fluid mixing (like building a pipe, changing recipe, rotating etc.) produce an error message as flying text.
* Replaced First steps campaign with Introduction campaign, available from the Start campaign menu.
=== Features ===
* Trains can be blueprinted and deconstructed.
* Trains can be given temporary stations (by Control+clicking the map). Temporary station is automatically removed once the train departures from it.
* Train stops without conditions work as waypoints. (the train doesn't stop at those)
* Added Passenger present and Passenger not present wait condition to the train conditions.
* If building of entity/blueprint fails, the reason of it is pinged as flying text.
* Map pings. Ctrl+Alt+click on the map to show a ping in all players maps at that location.
* Basic image tags format is [img=<image path>] where image path can use item, entity, technology, recipe, item-group, fluid tile, virtual signal achievement or utility icon.
** For example [img=item/iron-plate] or [img=item.iron-plate]. The "." instead of "/" usage is to make it usable in save names.
** Additionally, items/entities/technologies/recipe/item-group/fluid/tile/virtual signal or achievement can be linked directly by [item=iron-plate], [recipe=iron-plate], or [entity=small-biter] to provide tooltip for the appropriate object.
* Blueprint/special item tags.
** Shift clicking the icon in chat will create an item and place it in the cursor.
** Format is [special-item=blueprint string], eg: [special-item=0eNp1jtEKwjAMRX9l5rnCxkShvyIi3YxboU1Lm4lj9N9N54sv5iFwL/eeZIPBLRiTJQa9gR0DZdDXDbKdyLjq8RoRNFhGDwrI+Ko4GcoxJD4O6BiKAksPfIPuyk0BElu2+CXtYr3T4gdMEvjHUBBDllqgelVQrYJVdqnE/br+eVaBM1ITb0bnQvNMwTc8YzPOhiZ0YTpI5oUp78BL33YnmbY/l/IBb4pSQQ==].
** These tags also work with deconstruction and upgrade planners.
* Map ping tags: Created by shift-clicking the ground/map when the chat is open. Format is [gps=x,y], eg [gps=10,30] will show a map ping in all players maps at location 10,30.
** Clicking the icon in chat will open the map on the specified location.
* Font tags: Format is [font=debug-mono]mono text[/font].
* Color tags: Format is [color=1,0,0]red text[/font]
* Fast replacing pipes by pipes to ground similar to underground belts.
* When multiple versions of the same mod are installed you can select which version you want to use.
* The sync mods with save/multiplayer game feature can now sync mod startup settings as well as mods.
* Added support to import and export permissions.
* Closing opened items (blueprint books/armor) now remembers what GUI you previously had open.
* Filter inserters can be set to whitelist or blacklist filters.
* Added belt immunity equipment.
* Added upgrade planner.
* Added steam networking support for steam users.
* Added RGB support for Logitech hardware.
* Robots can blow up cliffs.
* Wave defense scenario has been reworked to support multiple rounds and a procedurally generated map.
* Added a research queue that becomes available after the player has finished the game by launching a rocket with satellite.
=== Minor Features ===
* Warning icon for automated trains that are out of fuel.
* Added 250 and 1000 hours precision intervals into statistics.
* Using deconstruction planner is incorporated in the latency hiding.
* Changed personal roboports so they won't send construction robots if you're driving in a vehicle that they can't keep up with or if in a train in automatic mode.
* Added an option to ignore mouse events when using accessibility zoom feature on macOS.
* Added support to change multiplayer config settings runtime.
* Added support to edit the whitelist, banlist, and admin list when hosting a multiplayer game.
* Added the Admin GUI (openable through /admin in the console) to manage multiplayer players.
* Landfill can be built by robots and be included in blueprints.
* Blueprint items taken from blueprint library will not move to player inventory when Q is pressed, but can be moved to any slot explicitly. (Same as with clipboard items)
* When selecting any item to the cursor from some of the player inventories. As long as the item is being held, hand icon is shown on the slot it was taken from. The hand prevents any other item to be inserted into the slot as long as the player cursor isn't cleared.
* When holding radar in cursor, area covered by existing radars is also highlighted on minimap.
* Configurable (in gui), the count of rolling stocks shown in the train visualization.
* Added two levels of shallow water tiles (only placed by map editor, not generated). Enemies and vehicles can travel over shallow water.
=== Graphics ===
* New graphics for:
** accumulator
** biters, spitters, worms, spawners
** chests
** electric poles and substation
** map edge transitions
** rocket silo
** transport belts, underground belts, splitters and transport belt circuit connector
** trees
** turrets (gun, flamethrower and laser)
** walls and gates
* laser turrets, personal laser defense and distractor robots now use new laser beams.
* Highlighting inserters that would interact with selected/previewed entity.
* Showing shield bars above health bar for relevant entities.
* Single vertical pipe is shorter.
=== Gui ===
* New final versions of several important GUI screens (Quick bar, Train Schedule, Load/Save Game, Settings, Map Generator, Research, Mods)
** Other screens than the mentioned ones (more than 100) have inconsistencies and will be updated in future minor updates.
* The quickbar is no longer an inventory, instead it can only hold shortcuts it items in inventory or blueprint library.
** The quickbar now has 10 pages of shortcuts.
** Player inventory increased by 20 slots to compensate. Toolbelt research further increases the player inventory.
* In the map, station and tag selection is now visualized by the standard Factorio selection box graphics instead of highlighting.
* Added interface option: When selecting a buildable item from the quickbar or when using the pipette tool, if you have no items of that type, a ghost will be placed in the cursor instead.
* When something is not buildable (manual or blueprint building), the reason of why it isn't buildable is shown as flying text over the cursor when the build is attempted.
* Only compatible results of a furnace are manually placeable in the result slot. (Mainly to avoid confusion of new players)
=== Optimisations ===
* Modernized and optimized rendering backend. The game now uses DirectX 11 or OpenGL 3.3 Core and requires DirectX 10 class graphics card.
* DirectX backend doesn't keep backup of all sprites in RAM anymore.
* Added high quality texture compression to reduce amount of video memory consumed by the game and increase overall rendering performance.
* Added texture streaming so that adding more sprites does not necessarily increase GPU requirements.
* Improved game startup performance when using a large amount of technologies with deep dependency trees (it's now 67,000 times faster).
* Optimized rendering of logistic overlay when zoomed in to map. ([https://forums.factorio.com/60659 more])
* Optimized rendering of turret ranges when zoomed in to map. ([https://forums.factorio.com/58991 more])
=== Changes ===
* Resource generation changed significantly:
** The starting area contains only iron, copper, coal and stone, in very predictable amounts. Uranium and oil are excluded from the starting area.
** Resource generation settings now have a much more dramatic effect. Increased the number of steps for each setting.
** Ore patches are slightly less frequent but richer.
** There will be a more balanced amount of resources within a large enough region.
** Many other small tweaks.
* Biter generation changed significantly:
** Biter richness slider removed, biter placement is only configured by size and frequency settings.
** Biter generation settings now have a much more dramatic effect. Increased the number of steps for each setting.
** Biter bases will increase in size, frequency and number of worms depending on the distance from player spawn.
** Worm size increases depending on the distance from player spawn.
** Small biter bases are now closer to the player spawn.
** At large distances from player spawn, biter base frequency is lower than before but biter bases are larger.
** Other small tweaks.
* Terrain generation changed significantly:
** Water is generated as large lakes instead of swamps.
** Tile generation improved. Tile placement respects biomes better.
** More predictable cliff placement.
** Better controls in the map generator GUI for water, tiles and cliffs.
* New map terrain type selectable: Island. Launch the rocket with only a limited amount of resources available on the map.
* Default resolution of the game is now 1920x1080.
* Increased player reach from 6 to 10.
* Inserters are putting science packs to the lab even when there is no research in progress or when the research doesn't need that particular pack.
* Default_request_amount removed in all places where it was used. Default logistic request is 1 stack, unless changed by the setting "Default request is 1".
* All personal equipment stack sizes changed to 20.
* Placing a tile will now clear any tile ghosts at that position. ([https://forums.factorio.com/59721 more])
* It is allowed to use unicode characters in save names.
* Recipes that have more ingredients than the assembling machine allows are now shown as red instead of not present when selecting the recipe.
* When the "Made in" row is shown in the recipe tooltip, player icon is added to the list when it is craftable by player.
* Increased ghost time to live of ghosts from 1 hour to 1 week.
* Since the catalysts have been tweaked, the kovarex enrichment process can now be used together with productivity module.
* Tile construction jobs are being handled by robots separately from entity building jobs, to prevent entity ghosts not being built due to large number of tile ghosts.
* Switched key bindings from key codes to scan codes. This solves an issue with bad default key bindings on layouts that are not similar to US QWERTY (ie. AZERTY).
* Armor no longer uses durability and all armor now has a stack size of 1.
* Manually putting modules into machines that are requesting modules from the logistic network will reduce the modules requested.
* Increased maximum train stop length from 50 to 100 characters so it can fit at least 3 tags in most cases.
* Items consumed by hand crafting are counted in item production statistics.
* Added --disable-migration-window command-line option to disable the "migrated content" gui.
* Removed tile properties debug overlay.
* Command-line map preview generator now shows biter nests.
* Items sent in a rocket are counted in item production statistics. ([https://forums.factorio.com/62606 more])
* Removed pickaxes and replaced them with research effects.
* Removed Wood from the game (And raw wood renamed to Wood).
* Added rotation smoothing to biters.
* Chests and wooden power poles are no longer usable as fuel.
* Burner efficiency is set to 100% for all entities and fuel value is halved to simplify calculations. This should not change game balance.
* Removed the hardness/mining power mechanics, we just have a mining speed and mining time now.
* Manual mining speed times of various entities will differ a bit, but probably not in a noticeable way.
* Stone and other ore mining speed has been unified to be 1 (apart uranium ore, which is 2 and shown as 200% mining time)
* Mining drill speed is now shown in the form of <x>/s (0.25/s for burner mining drill, 0.5/s for electric mining drill), the relative mining speeds of the mining machines have been decreased a little so the numbers are rounded nicely (0.28 -> 0.25 and 0.525 -> 0.5).
* Renamed the whitelist and banlist to server-whitelist and server-banlist.
* Added server-adminlist that's used to determine which people are admins when hosting any multiplayer game. This is synced both ways when hosting any game.
* Removed "admins" from the multiplayer server-settings file - they're now handled through server-adminlist.

== 0.17.0 ==
Date: 26. 02. 2019
=== Major Features ===
* New quickbar (more in Gui section)
* Added shortcut bar that allows quick access to certain game features, such as toggling alt mode, creating blueprints, or turning off personal roboport
* New gui style with final version of some parts of the GUI (More in Gui section)
* Added clipboard functionality. (Control + C, Control + X, Control + V activate appropriate tools) Shift + mouse wheel allows to cycle the clipboard history.
* Added undo functionality (Control + Z). Supports manual entity building and by blueprints and manual mining and usage of deconstruction planner.
* Reworked the Map Editor so it's now part of the standard game and can be toggled at will using the '/editor' command.
* Support for mod synchronisation when joining multiplayer game. Works as long as the used mods are on the mod portal.
* Fight changes. Enemy projectiles are dodgeable and slowdown/damage the target over time. They also leave splashes on ground that have the same effect.
* Rich text tags. These tags can be used almost anywhere: Chat, station names, save names, custom ui and probably a few places we didn't think of.
** They allow changing color, font, images and location/blueprint/armor/station/locomotive linking through chat. (More in features)
* Fluid mixing prevention. Actions that fail as they would lead to fluid mixing (like building a pipe, changing recipe, rotating etc.) produce an error message as flying text.
* Replaced First steps campaign with Introduction campaign, available from the Start campaign menu.
=== Features ===
* Trains can be blueprinted and deconstructed.
* Trains can be given temporary stations (by Control+clicking the map). Temporary station is automatically removed once the train departures from it.
* Train stops without conditions work as waypoints. (the train doesn't stop at those)
* Added Passenger present and Passenger not present wait condition to the train conditions.
* If building of entity/blueprint fails, the reason of it is pinged as flying text.
* Map pings. Ctrl+Alt+click on the map to show a ping in all players maps at that location.
* Basic image tags format is [img=<image path>] where image path can use item, entity, technology, recipe, item-group, fluid tile, virtual signal achievement or utility icon.
** For example [img=item/iron-plate] or [img=item.iron-plate]. The "." instead of "/" usage is to make it usable in save names.
** Additionally, items/entities/technologies/recipe/item-group/fluid/tile/virtual signal or achievement can be linked directly by [item=iron-plate], [recipe=iron-plate], or [entity=small-biter] to provide tooltip for the appropriate object.
* Blueprint/special item tags.
** Shift clicking the icon in chat will create an item and place it in the cursor.
** Format is [special-item=blueprint string], eg: [special-item=0eNp1jtEKwjAMRX9l5rnCxkShvyIi3YxboU1Lm4lj9N9N54sv5iFwL/eeZIPBLRiTJQa9gR0DZdDXDbKdyLjq8RoRNFhGDwrI+Ko4GcoxJD4O6BiKAksPfIPuyk0BElu2+CXtYr3T4gdMEvjHUBBDllqgelVQrYJVdqnE/br+eVaBM1ITb0bnQvNMwTc8YzPOhiZ0YTpI5oUp78BL33YnmbY/l/IBb4pSQQ==].
** These tags also work with deconstruction and upgrade planners.
* Map ping tags: Created by shift-clicking the ground/map when the chat is open. Format is [gps=x,y], eg [gps=10,30] will show a map ping in all players maps at location 10,30.
** Clicking the icon in chat will open the map on the specified location.
* Font tags: Format is [font=debug-mono]mono text[/font].
* Color tags: Format is [color=1,0,0]red text[/font]
* Fast replacing pipes by pipes to ground similar to underground belts.
* When multiple versions of the same mod are installed you can select which version you want to use.
* The sync mods with save/multiplayer game feature can now sync mod startup settings as well as mods.
* Added support to import and export permissions.
* Closing opened items (blueprint books/armor) now remembers what GUI you previously had open.
* Filter inserters can be set to whitelist or blacklist filters.
* Added belt immunity equipment.
* Added upgrade planner.
* Added steam networking support for steam users.
* Added RGB support for Logitech hardware.
* Robots can blow up cliffs.
* Wave defense scenario has been reworked to support multiple rounds and a procedurally generated map.
* Added a research queue that becomes available after the player has finished the game by launching a rocket with satellite.
=== Minor Features ===
* Warning icon for automated trains that are out of fuel.
* Added 250 and 1000 hours precision intervals into statistics.
* Using deconstruction planner is incorporated in the latency hiding.
* Changed personal roboports so they won't send construction robots if you're driving in a vehicle that they can't keep up with or if in a train in automatic mode.
* Added an option to ignore mouse events when using accessibility zoom feature on macOS.
* Added support to change multiplayer config settings runtime.

* Added the Admin GUI (openable through /admin in the console) to manage multiplayer players.
* Landfill can be built by robots and be included in blueprints.
* Blueprint items taken from blueprint library will not move to player inventory when Q is pressed, but can be moved to any slot explicitly. (Same as with clipboard items)
* When selecting any item to the cursor from some of the player inventories. As long as the item is being held, hand icon is shown on the slot it was taken from. The hand prevents any other item to be inserted into the slot as long as the player cursor isn't cleared.
* When holding radar in cursor, area covered by existing radars is also highlighted on minimap.
* Configurable (in gui), the count of rolling stocks shown in the train visualization.
* Added two levels of shallow water tiles (only placed by map editor, not generated). Enemies and vehicles can travel over shallow water.

** chests
** electric poles and substation
** map edge transitions
** rocket silo
** transport belts, underground belts, splitters and transport belt circuit connector

** turrets (gun, flamethrower and laser)
** walls and gates
* laser turrets, personal laser defense and distractor robots now use new laser beams.
* Highlighting inserters that would interact with selected/previewed entity.
* Showing shield bars above health bar for relevant entities.
* Single vertical pipe is shorter.
=== Gui ===
* New final versions of several important GUI screens (Quick bar, Train Schedule, Load/Save Game, Settings, Map Generator, Research, Mods)
** Other screens than the mentioned ones (more than 100) have inconsistencies and will be updated in future minor updates.
* The quickbar is no longer an inventory, instead it can only hold shortcuts it items in inventory or blueprint library.
** The quickbar now has 10 pages of shortcuts.
** Player inventory increased by 20 slots to compensate. Toolbelt research further increases the player inventory.
* In the map, station and tag selection is now visualized by the standard Factorio selection box graphics instead of highlighting.
* Added interface option: When selecting a buildable item from the quickbar or when using the pipette tool, if you have no items of that type, a ghost will be placed in the cursor instead.
* When something is not buildable (manual or blueprint building), the reason of why it isn't buildable is shown as flying text over the cursor when the build is attempted.
* Only compatible results of a furnace are manually placeable in the result slot. (Mainly to avoid confusion of new players)
=== Optimisations ===
* Modernized and optimized rendering backend. The game now uses DirectX 11 or OpenGL 3.3 Core and requires DirectX 10 class graphics card.
* DirectX backend doesn't keep backup of all sprites in RAM anymore.
* Added high quality texture compression to reduce amount of video memory consumed by the game and increase overall rendering performance.
* Added texture streaming so that adding more sprites does not necessarily increase GPU requirements.
* Improved game startup performance when using a large amount of technologies with deep dependency trees (it's now 67,000 times faster).
* Optimized rendering of logistic overlay when zoomed in to map. ([https://forums.factorio.com/60659 more])
* Optimized rendering of turret ranges when zoomed in to map. ([https://forums.factorio.com/58991 more])
=== Changes ===

** Biter bases will increase in size, frequency and number of worms depending on the distance from player spawn.
** Worm size increases depending on the distance from player spawn.
** Small biter bases are now closer to the player spawn.
** At large distances from player spawn, biter base frequency is lower than before but biter bases are larger.
** Other small tweaks.
* Terrain generation changed significantly:
** Water is generated as large lakes instead of swamps.
** Tile generation improved. Tile placement respects biomes better.
** More predictable cliff placement.
** Better controls in the map generator GUI for water, tiles and cliffs.

* When the "Made in" row is shown in the recipe tooltip, player icon is added to the list when it is craftable by player.
* Increased ghost time to live of ghosts from 1 hour to 1 week.
* Since the catalysts have been tweaked, the kovarex enrichment process can now be used together with productivity module.
* Tile construction jobs are being handled by robots separately from entity building jobs, to prevent entity ghosts not being built due to large number of tile ghosts.
* Switched key bindings from key codes to scan codes. This solves an issue with bad default key bindings on layouts that are not similar to US QWERTY (ie. AZERTY).
* Armor no longer uses durability and all armor now has a stack size of 1.
* Manually putting modules into machines that are requesting modules from the logistic network will reduce the modules requested.
* Increased maximum train stop length from 50 to 100 characters so it can fit at least 3 tags in most cases.
* Items consumed by hand crafting are counted in item production statistics.
* Added --disable-migration-window command-line option to disable the "migrated content" gui.

* Removed Wood from the game (And raw wood renamed to Wood).
* Added rotation smoothing to biters.
* Chests and wooden power poles are no longer usable as fuel.
* Burner efficiency is set to 100% for all entities and fuel value is halved to simplify calculations. This should not change game balance.
* Removed the hardness/mining power mechanics, we just have a mining speed and mining time now.
* Manual mining speed times of various entities will differ a bit, but probably not in a noticeable way.
* Stone and other ore mining speed has been unified to be 1 (apart uranium ore, which is 2 and shown as 200% mining time)
* Mining drill speed is now shown in the form of <x>/s (0.25/s for burner mining drill, 0.5/s for electric mining drill), the relative mining speeds of the mining machines have been decreased a little so the numbers are rounded nicely (0.28 -> 0.25 and 0.525 -> 0.5).
* Renamed the whitelist and banlist to server-whitelist and server-banlist.
* Added server-adminlist that's used to determine which people are admins when hosting any multiplayer game. This is synced both ways when hosting any game.
* Removed "admins" from the multiplayer server-settings file - they're now handled through server-adminlist.
* "Z" (drop item) will drop single items into what ever entity is selected instead of only dropping on the ground.
* Stickers can by applied onto cars and tanks now.
* Changed the chat gray-out mechanism. It always greyed-out after 5 seconds to 70% alpha, and then stayed depending on the setting. Now it stays 100% and only greys out away in the last 2 seconds.
* Placing entities or paths removes tree stumps and biter corpses.
* Removed New Hope campaign.

== 0.17.0 ==
Date: 26. 02. 2019
=== Major Features ===
* New quickbar (more in Gui section)
* Added shortcut bar that allows quick access to certain game features, such as toggling alt mode, creating blueprints, or turning off personal roboport
* New gui style with final version of some parts of the GUI (More in Gui section)
* Added clipboard functionality. (Control + C, Control + X, Control + V activate appropriate tools) Shift + mouse wheel allows to cycle the clipboard history.
* Added undo functionality (Control + Z). Supports manual entity building and by blueprints and manual mining and usage of deconstruction planner.
* Reworked the Map Editor so it's now part of the standard game and can be toggled at will using the '/editor' command.
* Support for mod synchronisation when joining multiplayer game. Works as long as the used mods are on the mod portal.
* Fight changes. Enemy projectiles are dodgeable and slowdown/damage the target over time. They also leave splashes on ground that have the same effect.
* Rich text tags. These tags can be used almost anywhere: Chat, station names, save names, custom ui and probably a few places we didn't think of.
** They allow changing color, font, images and location/blueprint/armor/station/locomotive linking through chat. (More in features)
* Fluid mixing prevention. Actions that fail as they would lead to fluid mixing (like building a pipe, changing recipe, rotating etc.) produce an error message as flying text.
* Replaced First steps campaign with Introduction campaign, available from the Start campaign menu.
=== Features ===
* Trains can be blueprinted and deconstructed.
* Trains can be given temporary stations (by Control+clicking the map). Temporary station is automatically removed once the train departures from it.
* Train stops without conditions work as waypoints. (the train doesn't stop at those)
* Added Passenger present and Passenger not present wait condition to the train conditions.
* If building of entity/blueprint fails, the reason of it is pinged as flying text.
* Map pings. Ctrl+Alt+click on the map to show a ping in all players maps at that location.
* Basic image tags format is [img=<image path>] where image path can use item, entity, technology, recipe, item-group, fluid tile, virtual signal achievement or utility icon.
** For example [img=item/iron-plate] or [img=item.iron-plate]. The "." instead of "/" usage is to make it usable in save names.
** Additionally, items/entities/technologies/recipe/item-group/fluid/tile/virtual signal or achievement can be linked directly by [item=iron-plate], [recipe=iron-plate], or [entity=small-biter] to provide tooltip for the appropriate object.
* Blueprint/special item tags.
** Shift clicking the icon in chat will create an item and place it in the cursor.
** Format is [special-item=blueprint string], eg: [special-item=0eNp1jtEKwjAMRX9l5rnCxkShvyIi3YxboU1Lm4lj9N9N54sv5iFwL/eeZIPBLRiTJQa9gR0DZdDXDbKdyLjq8RoRNFhGDwrI+Ko4GcoxJD4O6BiKAksPfIPuyk0BElu2+CXtYr3T4gdMEvjHUBBDllqgelVQrYJVdqnE/br+eVaBM1ITb0bnQvNMwTc8YzPOhiZ0YTpI5oUp78BL33YnmbY/l/IBb4pSQQ==].
** These tags also work with deconstruction and upgrade planners.
* Map ping tags: Created by shift-clicking the ground/map when the chat is open. Format is [gps=x,y], eg [gps=10,30] will show a map ping in all players maps at location 10,30.
** Clicking the icon in chat will open the map on the specified location.
* Font tags: Format is [font=debug-mono]mono text[/font].
* Color tags: Format is [color=1,0,0]red text[/font]
* Fast replacing pipes by pipes to ground similar to underground belts.
* When multiple versions of the same mod are installed you can select which version you want to use.
* The sync mods with save/multiplayer game feature can now sync mod startup settings as well as mods.
* Added support to import and export permissions.
* Closing opened items (blueprint books/armor) now remembers what GUI you previously had open.
* Filter inserters can be set to whitelist or blacklist filters.
* Added belt immunity equipment.
* Added upgrade planner.
* Added steam networking support for steam users.
* Added RGB support for Logitech hardware.
* Robots can blow up cliffs.
* Wave defense scenario has been reworked to support multiple rounds and a procedurally generated map.
* Added a research queue that becomes available after the player has finished the game by launching a rocket with satellite.
=== Minor Features ===
* Warning icon for automated trains that are out of fuel.
* Added 250 and 1000 hours precision intervals into statistics.
* Using deconstruction planner is incorporated in the latency hiding.
* Changed personal roboports so they won't send construction robots if you're driving in a vehicle that they can't keep up with or if in a train in automatic mode.
* Added an option to ignore mouse events when using accessibility zoom feature on macOS.
* Added support to change multiplayer config settings runtime.
* Added support to edit the whitelist, banlist, and admin list when hosting a multiplayer game.
* Added the Admin GUI (openable through /admin in the console) to manage multiplayer players.
* Landfill can be built by robots and be included in blueprints.
* Blueprint items taken from blueprint library will not move to player inventory when Q is pressed, but can be moved to any slot explicitly. (Same as with clipboard items)
* When selecting any item to the cursor from some of the player inventories. As long as the item is being held, hand icon is shown on the slot it was taken from. The hand prevents any other item to be inserted into the slot as long as the player cursor isn't cleared.
* When holding radar in cursor, area covered by existing radars is also highlighted on minimap.
* Configurable (in gui), the count of rolling stocks shown in the train visualization.
* Added two levels of shallow water tiles (only placed by map editor, not generated). Enemies and vehicles can travel over shallow water.
=== Graphics ===
* New graphics for:
** accumulator
** biters, spitters, worms, spawners
** chests
** electric poles and substation
** map edge transitions
** rocket silo
** transport belts, underground belts, splitters and transport belt circuit connector
** trees
** turrets (gun, flamethrower and laser)
** walls and gates
* laser turrets, personal laser defense and distractor robots now use new laser beams.
* Highlighting inserters that would interact with selected/previewed entity.
* Showing shield bars above health bar for relevant entities.
* Single vertical pipe is shorter.
=== Gui ===
* New final versions of several important GUI screens (Quick bar, Train Schedule, Load/Save Game, Settings, Map Generator, Research, Mods)
** Other screens than the mentioned ones (more than 100) have inconsistencies and will be updated in future minor updates.
* The quickbar is no longer an inventory, instead it can only hold shortcuts it items in inventory or blueprint library.
** The quickbar now has 10 pages of shortcuts.
** Player inventory increased by 20 slots to compensate. Toolbelt research further increases the player inventory.
* In the map, station and tag selection is now visualized by the standard Factorio selection box graphics instead of highlighting.
* Added interface option: When selecting a buildable item from the quickbar or when using the pipette tool, if you have no items of that type, a ghost will be placed in the cursor instead.
* When something is not buildable (manual or blueprint building), the reason of why it isn't buildable is shown as flying text over the cursor when the build is attempted.
* Only compatible results of a furnace are manually placeable in the result slot. (Mainly to avoid confusion of new players)
=== Optimisations ===
* Modernized and optimized rendering backend. The game now uses DirectX 11 or OpenGL 3.3 Core and requires DirectX 10 class graphics card.
* DirectX backend doesn't keep backup of all sprites in RAM anymore.
* Added high quality texture compression to reduce amount of video memory consumed by the game and increase overall rendering performance.
* Added texture streaming so that adding more sprites does not necessarily increase GPU requirements.
* Improved game startup performance when using a large amount of technologies with deep dependency trees (it's now 67,000 times faster).
* Optimized rendering of logistic overlay when zoomed in to map. ([https://forums.factorio.com/60659 more])
* Optimized rendering of turret ranges when zoomed in to map. ([https://forums.factorio.com/58991 more])
=== Changes ===
* Resource generation changed significantly:
** The starting area contains only iron, copper, coal and stone, in very predictable amounts. Uranium and oil are excluded from the starting area.
** Resource generation settings now have a much more dramatic effect. Increased the number of steps for each setting.
** Ore patches are slightly less frequent but richer.
** There will be a more balanced amount of resources within a large enough region.
** Many other small tweaks.
* Biter generation changed significantly:
** Biter richness slider removed, biter placement is only configured by size and frequency settings.
** Biter generation settings now have a much more dramatic effect. Increased the number of steps for each setting.
** Biter bases will increase in size, frequency and number of worms depending on the distance from player spawn.
** Worm size increases depending on the distance from player spawn.
** Small biter bases are now closer to the player spawn.
** At large distances from player spawn, biter base frequency is lower than before but biter bases are larger.
** Other small tweaks.
* Terrain generation changed significantly:
** Water is generated as large lakes instead of swamps.
** Tile generation improved. Tile placement respects biomes better.
** More predictable cliff placement.
** Better controls in the map generator GUI for water, tiles and cliffs.
* New map terrain type selectable: Island. Launch the rocket with only a limited amount of resources available on the map.
* Default resolution of the game is now 1920x1080.
* Increased player reach from 6 to 10.
* Inserters are putting science packs to the lab even when there is no research in progress or when the research doesn't need that particular pack.
* Default_request_amount removed in all places where it was used. Default logistic request is 1 stack, unless changed by the setting "Default request is 1".
* All personal equipment stack sizes changed to 20.
* Placing a tile will now clear any tile ghosts at that position. ([https://forums.factorio.com/59721 more])
* It is allowed to use unicode characters in save names.
* Recipes that have more ingredients than the assembling machine allows are now shown as red instead of not present when selecting the recipe.
* When the "Made in" row is shown in the recipe tooltip, player icon is added to the list when it is craftable by player.
* Increased ghost time to live of ghosts from 1 hour to 1 week.
* Since the catalysts have been tweaked, the kovarex enrichment process can now be used together with productivity module.
* Tile construction jobs are being handled by robots separately from entity building jobs, to prevent entity ghosts not being built due to large number of tile ghosts.
* Switched key bindings from key codes to scan codes. This solves an issue with bad default key bindings on layouts that are not similar to US QWERTY (ie. AZERTY).
* Armor no longer uses durability and all armor now has a stack size of 1.
* Manually putting modules into machines that are requesting modules from the logistic network will reduce the modules requested.
* Increased maximum train stop length from 50 to 100 characters so it can fit at least 3 tags in most cases.
* Items consumed by hand crafting are counted in item production statistics.
* Added --disable-migration-window command-line option to disable the "migrated content" gui.
* Removed tile properties debug overlay.
* Command-line map preview generator now shows biter nests.
* Items sent in a rocket are counted in item production statistics. ([https://forums.factorio.com/62606 more])
* Removed pickaxes and replaced them with research effects.
* Removed Wood from the game (And raw wood renamed to Wood).
* Added rotation smoothing to biters.
* Chests and wooden power poles are no longer usable as fuel.
* Burner efficiency is set to 100% for all entities and fuel value is halved to simplify calculations. This should not change game balance.
* Removed the hardness/mining power mechanics, we just have a mining speed and mining time now.
* Manual mining speed times of various entities will differ a bit, but probably not in a noticeable way.
* Stone and other ore mining speed has been unified to be 1 (apart uranium ore, which is 2 and shown as 200% mining time)
* Mining drill speed is now shown in the form of <x>/s (0.25/s for burner mining drill, 0.5/s for electric mining drill), the relative mining speeds of the mining machines have been decreased a little so the numbers are rounded nicely (0.28 -> 0.25 and 0.525 -> 0.5).
* Renamed the whitelist and banlist to server-whitelist and server-banlist.
* Added server-adminlist that's used to determine which people are admins when hosting any multiplayer game. This is synced both ways when hosting any game.
* Removed "admins" from the multiplayer server-settings file - they're now handled through server-adminlist.
* "Z" (drop item) will drop single items into what ever entity is selected instead of only dropping on the ground.
* Stickers can by applied onto cars and tanks now.
* Changed the chat gray-out mechanism. It always greyed-out after 5 seconds to 70% alpha, and then stayed depending on the setting. Now it stays 100% and only greys out away in the last 2 seconds.
* Placing entities or paths removes tree stumps and biter corpses.
* Removed New Hope campaign.
=== Balancing ===
* Technology pre-requisites tweaked so the unlocked item(s) always have all the ingredients already unlocked as well. This means many small changes.
* Science pack names changed:
** Science pack -> Automation science pack
** Science pack 2 -> Logistic science pack
** Science pack 3 -> Chemical science pack
** High-tech science pack -> Utility science pack
** Military, Production and Space science pack names remain the same.

** Chemical science pack now crafts in pairs.
** Production science pack now requires 1x Electric furnace, 1x Productivity module, 30x Rail.
** Production science pack now produces in groups of 3. Crafting time rescaled to match.
** Utility science pack now requires 2x Processing unit, 1x Flying robot frame, 3x Low density structure.
** Utility science pack now produces in groups of 3. Crafting time rescaled to match.
* Some technologies more clearly split between Production and Utility science packs:
** Production science pack:
*** Effect transmission

*** Kovarex enrichment process & Nuclear fuel reprocessing
*** Worker robot capacity 2
** Utility science pack:
*** Logistic system
*** Worker robot speed 3
*** Military 4 and weapon unlocks/upgrades
*** Power armor mk2 and Portable fusion reactor
** Both Production and Utility science packs are required only for Rocket silo, Atomic bomb and some high-tier upgrades.
* Every science pack now has a technology to unlock it. Some technology prerequisites changed slightly. Space science pack technology unlocks the Satellite.
* Rocket fuel, Low density structure and Rocket control unit are unlocked by their own technologies.
* The game is won by launching a rocket, the Satellite is only for getting Space science packs.
* Swapped sorting order of Military science pack and Chemical science packs because Military science pack does not need oil.
* Nuclear power technology split to Uranium processing and Nuclear power.
* Nuclear fuel reprocessing technology cost reduced from 1500 to 50.
* Lubricant technology added (pre-requisite for Electric engine and Logistics 3)
* Fast and Filter inserters are unlocked by their own technology with a pre-requisite of Electronics.
* Automation 2 is a pre-requisite for Fluid handling. (Assembling machine 1 can't handle fluids)
* Engine is a pre-requisite for Fluid handling. (Pump needs Engines to craft it)
* Pump is now unlocked by Fluid handling. (was Engine)
* Fluid handling is a pre-requisite for Oil processing.
* Item spacing on transport belts changed from 0.28 tiles to 0.25 tiles, giving a transport belts throughput of 15/30/45 (basic/fast/express) items per second.
* Iron plate, copper plate and stone brick crafting time reduced from 3.5 to 3.2, steel plate crafting time reduced from 17.5 to 16.
* Coal liquefaction now produces 90 Heavy oil, 20 Light oil and 10 Petroleum gas, consuming 25 Heavy oil, 10 Coal and 50 Steam. (Gaining much more Heavy oil, less Light oil and Petroleum gas)
* Low density structure now requires 2x Steel plate, 20x Copper plate, 5x Plastic bar.
* Low density structure crafting time reduced from 30 to 20.
* Medium and Big power pole recipes now use iron sticks.
* Train stop recipe now uses iron sticks.

* Added shortcut bar that allows quick access to certain game features, such as toggling alt mode, creating blueprints, or turning off personal roboport
* New gui style with final version of some parts of the GUI (More in Gui section)
* Added clipboard functionality. (Control + C, Control + X, Control + V activate appropriate tools) Shift + mouse wheel allows to cycle the clipboard history.
* Added undo functionality (Control + Z). Supports manual entity building and by blueprints and manual mining and usage of deconstruction planner.
* Reworked the Map Editor so it's now part of the standard game and can be toggled at will using the '/editor' command.
* Support for mod synchronisation when joining multiplayer game. Works as long as the used mods are on the mod portal.
* Fight changes. Enemy projectiles are dodgeable and slowdown/damage the target over time. They also leave splashes on ground that have the same effect.
* Rich text tags. These tags can be used almost anywhere: Chat, station names, save names, custom ui and probably a few places we didn't think of.
** They allow changing color, font, images and location/blueprint/armor/station/locomotive linking through chat. (More in features)
* Fluid mixing prevention. Actions that fail as they would lead to fluid mixing (like building a pipe, changing recipe, rotating etc.) produce an error message as flying text.
* Replaced First steps campaign with Introduction campaign, available from the Start campaign menu.
=== Features ===
* Trains can be blueprinted and deconstructed.
* Trains can be given temporary stations (by Control+clicking the map). Temporary station is automatically removed once the train departures from it.
* Train stops without conditions work as waypoints. (the train doesn't stop at those)
* Added Passenger present and Passenger not present wait condition to the train conditions.
* If building of entity/blueprint fails, the reason of it is pinged as flying text.
* Map pings. Ctrl+Alt+click on the map to show a ping in all players maps at that location.
* Basic image tags format is [img=<image path>] where image path can use item, entity, technology, recipe, item-group, fluid tile, virtual signal achievement or utility icon.
** For example [img=item/iron-plate] or [img=item.iron-plate]. The "." instead of "/" usage is to make it usable in save names.
** Additionally, items/entities/technologies/recipe/item-group/fluid/tile/virtual signal or achievement can be linked directly by [item=iron-plate], [recipe=iron-plate], or [entity=small-biter] to provide tooltip for the appropriate object.
* Blueprint/special item tags.
** Shift clicking the icon in chat will create an item and place it in the cursor.
** Format is [special-item=blueprint string], eg: [special-item=0eNp1jtEKwjAMRX9l5rnCxkShvyIi3YxboU1Lm4lj9N9N54sv5iFwL/eeZIPBLRiTJQa9gR0DZdDXDbKdyLjq8RoRNFhGDwrI+Ko4GcoxJD4O6BiKAksPfIPuyk0BElu2+CXtYr3T4gdMEvjHUBBDllqgelVQrYJVdqnE/br+eVaBM1ITb0bnQvNMwTc8YzPOhiZ0YTpI5oUp78BL33YnmbY/l/IBb4pSQQ==].
** These tags also work with deconstruction and upgrade planners.
* Map ping tags: Created by shift-clicking the ground/map when the chat is open. Format is [gps=x,y], eg [gps=10,30] will show a map ping in all players maps at location 10,30.
** Clicking the icon in chat will open the map on the specified location.
* Font tags: Format is [font=debug-mono]mono text[/font].
* Color tags: Format is [color=1,0,0]red text[/font]

* When holding radar in cursor, area covered by existing radars is also highlighted on minimap.
* Configurable (in gui), the count of rolling stocks shown in the train visualization.

** Other screens than the mentioned ones (more than 100) have inconsistencies and will be updated in future minor updates.
* The quickbar is no longer an inventory, instead it can only hold shortcuts it items in inventory or blueprint library.
** The quickbar now has 10 pages of shortcuts.
** Player inventory increased by 20 slots to compensate. Toolbelt research further increases the player inventory.
* In the map, station and tag selection is now visualized by the standard Factorio selection box graphics instead of highlighting.
* Added interface option: When selecting a buildable item from the quickbar or when using the pipette tool, if you have no items of that type, a ghost will be placed in the cursor instead.
* When something is not buildable (manual or blueprint building), the reason of why it isn't buildable is shown as flying text over the cursor when the build is attempted.
* Only compatible results of a furnace are manually placeable in the result slot. (Mainly to avoid confusion of new players)
=== Optimisations ===
* Modernized and optimized rendering backend. The game now uses DirectX 11 or OpenGL 3.3 Core and requires DirectX 10 class graphics card.
* DirectX backend doesn't keep backup of all sprites in RAM anymore.
* Added high quality texture compression to reduce amount of video memory consumed by the game and increase overall rendering performance.
* Added texture streaming so that adding more sprites does not necessarily increase GPU requirements.
* Improved game startup performance when using a large amount of technologies with deep dependency trees (it's now 67,000 times faster).
* Optimized rendering of logistic overlay when zoomed in to map. ([https://forums.factorio.com/60659 more])
* Optimized rendering of turret ranges when zoomed in to map. ([https://forums.factorio.com/58991 more])
=== Changes ===
* Resource generation changed significantly:
** The starting area contains only iron, copper, coal and stone, in very predictable amounts. Uranium and oil are excluded from the starting area.
** Resource generation settings now have a much more dramatic effect. Increased the number of steps for each setting.
** Ore patches are slightly less frequent but richer.
** There will be a more balanced amount of resources within a large enough region.
** Many other small tweaks.
* Biter generation changed significantly:
** Biter richness slider removed, biter placement is only configured by size and frequency settings.
** Biter generation settings now have a much more dramatic effect. Increased the number of steps for each setting.
** Biter bases will increase in size, frequency and number of worms depending on the distance from player spawn.
** Worm size increases depending on the distance from player spawn.
** Small biter bases are now closer to the player spawn.
** At large distances from player spawn, biter base frequency is lower than before but biter bases are larger.
** Other small tweaks.
* Terrain generation changed significantly:
** Water is generated as large lakes instead of swamps.
** Tile generation improved. Tile placement respects biomes better.
** More predictable cliff placement.
** Better controls in the map generator GUI for water, tiles and cliffs.
* New map terrain type selectable: Island. Launch the rocket with only a limited amount of resources available on the map.
* Default resolution of the game is now 1920x1080.
* Increased player reach from 6 to 10.
* Inserters are putting science packs to the lab even when there is no research in progress or when the research doesn't need that particular pack.
* Default_request_amount removed in all places where it was used. Default logistic request is 1 stack, unless changed by the setting "Default request is 1".
* All personal equipment stack sizes changed to 20.
* Placing a tile will now clear any tile ghosts at that position. ([https://forums.factorio.com/59721 more])
* It is allowed to use unicode characters in save names.
* Recipes that have more ingredients than the assembling machine allows are now shown as red instead of not present when selecting the recipe.
* When the "Made in" row is shown in the recipe tooltip, player icon is added to the list when it is craftable by player.
* Increased ghost time to live of ghosts from 1 hour to 1 week.
* Since the catalysts have been tweaked, the kovarex enrichment process can now be used together with productivity module.
* Tile construction jobs are being handled by robots separately from entity building jobs, to prevent entity ghosts not being built due to large number of tile ghosts.
* Switched key bindings from key codes to scan codes. This solves an issue with bad default key bindings on layouts that are not similar to US QWERTY (ie. AZERTY).
* Armor no longer uses durability and all armor now has a stack size of 1.
* Manually putting modules into machines that are requesting modules from the logistic network will reduce the modules requested.
* Increased maximum train stop length from 50 to 100 characters so it can fit at least 3 tags in most cases.
* Items consumed by hand crafting are counted in item production statistics.
* Added --disable-migration-window command-line option to disable the "migrated content" gui.
* Removed tile properties debug overlay.
* Command-line map preview generator now shows biter nests.
* Items sent in a rocket are counted in item production statistics. ([https://forums.factorio.com/62606 more])
* Removed pickaxes and replaced them with research effects.
* Removed Wood from the game (And raw wood renamed to Wood).
* Added rotation smoothing to biters.
* Chests and wooden power poles are no longer usable as fuel.
* Burner efficiency is set to 100% for all entities and fuel value is halved to simplify calculations. This should not change game balance.
* Removed the hardness/mining power mechanics, we just have a mining speed and mining time now.
* Manual mining speed times of various entities will differ a bit, but probably not in a noticeable way.
* Stone and other ore mining speed has been unified to be 1 (apart uranium ore, which is 2 and shown as 200% mining time)
* Mining drill speed is now shown in the form of <x>/s (0.25/s for burner mining drill, 0.5/s for electric mining drill), the relative mining speeds of the mining machines have been decreased a little so the numbers are rounded nicely (0.28 -> 0.25 and 0.525 -> 0.5).
* Renamed the whitelist and banlist to server-whitelist and server-banlist.
* Added server-adminlist that's used to determine which people are admins when hosting any multiplayer game. This is synced both ways when hosting any game.
* Removed "admins" from the multiplayer server-settings file - they're now handled through server-adminlist.
* "Z" (drop item) will drop single items into what ever entity is selected instead of only dropping on the ground.
* Stickers can by applied onto cars and tanks now.
* Changed the chat gray-out mechanism. It always greyed-out after 5 seconds to 70% alpha, and then stayed depending on the setting. Now it stays 100% and only greys out away in the last 2 seconds.
* Placing entities or paths removes tree stumps and biter corpses.
* Removed New Hope campaign.

* New gui style with final version of some parts of the GUI (More in Gui section)
* Added clipboard functionality. (Control + C, Control + X, Control + V activate appropriate tools) Shift + mouse wheel allows to cycle the clipboard history.
* Added undo functionality (Control + Z). Supports manual entity building and by blueprints and manual mining and usage of deconstruction planner.
* Reworked the Map Editor so it's now part of the standard game and can be toggled at will using the '/editor' command.
* Support for mod synchronisation when joining multiplayer game. Works as long as the used mods are on the mod portal.
* Fight changes. Enemy projectiles are dodgeable and slowdown/damage the target over time. They also leave splashes on ground that have the same effect.
* Rich text tags. These tags can be used almost anywhere: Chat, station names, save names, custom ui and probably a few places we didn't think of.
** They allow changing color, font, images and location/blueprint/armor/station/locomotive linking through chat. (More in features)
* Fluid mixing prevention. Actions that fail as they would lead to fluid mixing (like building a pipe, changing recipe, rotating etc.) produce an error message as flying text.
* Replaced First steps campaign with Introduction campaign, available from the Start campaign menu.
=== Features ===
* Trains can be blueprinted and deconstructed.
* Trains can be given temporary stations (by Control+clicking the map). Temporary station is automatically removed once the train departures from it.
* Train stops without conditions work as waypoints. (the train doesn't stop at those)
* Added Passenger present and Passenger not present wait condition to the train conditions.
* If building of entity/blueprint fails, the reason of it is pinged as flying text.
* Map pings. Ctrl+Alt+click on the map to show a ping in all players maps at that location.
* Basic image tags format is [img=<image path>] where image path can use item, entity, technology, recipe, item-group, fluid tile, virtual signal achievement or utility icon.
** For example [img=item/iron-plate] or [img=item.iron-plate]. The "." instead of "/" usage is to make it usable in save names.
** Additionally, items/entities/technologies/recipe/item-group/fluid/tile/virtual signal or achievement can be linked directly by [item=iron-plate], [recipe=iron-plate], or [entity=small-biter] to provide tooltip for the appropriate object.
* Blueprint/special item tags.
** Shift clicking the icon in chat will create an item and place it in the cursor.
** Format is [special-item=blueprint string], eg: [special-item=0eNp1jtEKwjAMRX9l5rnCxkShvyIi3YxboU1Lm4lj9N9N54sv5iFwL/eeZIPBLRiTJQa9gR0DZdDXDbKdyLjq8RoRNFhGDwrI+Ko4GcoxJD4O6BiKAksPfIPuyk0BElu2+CXtYr3T4gdMEvjHUBBDllqgelVQrYJVdqnE/br+eVaBM1ITb0bnQvNMwTc8YzPOhiZ0YTpI5oUp78BL33YnmbY/l/IBb4pSQQ==].
** These tags also work with deconstruction and upgrade planners.
* Map ping tags: Created by shift-clicking the ground/map when the chat is open. Format is [gps=x,y], eg [gps=10,30] will show a map ping in all players maps at location 10,30.
** Clicking the icon in chat will open the map on the specified location.
* Font tags: Format is [font=debug-mono]mono text[/font].
* Color tags: Format is [color=1,0,0]red text[/font]
* Fast replacing pipes by pipes to ground similar to underground belts.
* When multiple versions of the same mod are installed you can select which version you want to use.
* The sync mods with save/multiplayer game feature can now sync mod startup settings as well as mods.
* Added support to import and export permissions.
* Closing opened items (blueprint books/armor) now remembers what GUI you previously had open.
* Filter inserters can be set to whitelist or blacklist filters.
* Added belt immunity equipment.
* Added upgrade planner.
* Added steam networking support for steam users.
* Added RGB support for Logitech hardware.
* Robots can blow up cliffs.
* Wave defense scenario has been reworked to support multiple rounds and a procedurally generated map.
* Added a research queue that becomes available after the player has finished the game by launching a rocket with satellite.
=== Minor Features ===
* Warning icon for automated trains that are out of fuel.
* Added 250 and 1000 hours precision intervals into statistics.
* Using deconstruction planner is incorporated in the latency hiding.
* Changed personal roboports so they won't send construction robots if you're driving in a vehicle that they can't keep up with or if in a train in automatic mode.
* Added an option to ignore mouse events when using accessibility zoom feature on macOS.
* Added support to change multiplayer config settings runtime.
* Added support to edit the whitelist, banlist, and admin list when hosting a multiplayer game.
* Added the Admin GUI (openable through /admin in the console) to manage multiplayer players.
* Landfill can be built by robots and be included in blueprints.
* Blueprint items taken from blueprint library will not move to player inventory when Q is pressed, but can be moved to any slot explicitly. (Same as with clipboard items)
* When selecting any item to the cursor from some of the player inventories. As long as the item is being held, hand icon is shown on the slot it was taken from. The hand prevents any other item to be inserted into the slot as long as the player cursor isn't cleared.
* When holding radar in cursor, area covered by existing radars is also highlighted on minimap.
* Configurable (in gui), the count of rolling stocks shown in the train visualization.
* Added two levels of shallow water tiles (only placed by map editor, not generated). Enemies and vehicles can travel over shallow water.
=== Graphics ===
* New graphics for:

** biters, spitters, worms, spawners
** chests
** electric poles and substation
** map edge transitions
** rocket silo
** transport belts, underground belts, splitters and transport belt circuit connector
** trees
** turrets (gun, flamethrower and laser)
** walls and gates
* laser turrets, personal laser defense and distractor robots now use new laser beams.
* Highlighting inserters that would interact with selected/previewed entity.
* Showing shield bars above health bar for relevant entities.
* Single vertical pipe is shorter.
=== Gui ===
* New final versions of several important GUI screens (Quick bar, Train Schedule, Load/Save Game, Settings, Map Generator, Research, Mods)
** Other screens than the mentioned ones (more than 100) have inconsistencies and will be updated in future minor updates.
* The quickbar is no longer an inventory, instead it can only hold shortcuts it items in inventory or blueprint library.
** The quickbar now has 10 pages of shortcuts.
** Player inventory increased by 20 slots to compensate. Toolbelt research further increases the player inventory.
* In the map, station and tag selection is now visualized by the standard Factorio selection box graphics instead of highlighting.
* Added interface option: When selecting a buildable item from the quickbar or when using the pipette tool, if you have no items of that type, a ghost will be placed in the cursor instead.
* When something is not buildable (manual or blueprint building), the reason of why it isn't buildable is shown as flying text over the cursor when the build is attempted.
* Only compatible results of a furnace are manually placeable in the result slot. (Mainly to avoid confusion of new players)
=== Optimisations ===
* Modernized and optimized rendering backend. The game now uses DirectX 11 or OpenGL 3.3 Core and requires DirectX 10 class graphics card.
* DirectX backend doesn't keep backup of all sprites in RAM anymore.
* Added high quality texture compression to reduce amount of video memory consumed by the game and increase overall rendering performance.
* Added texture streaming so that adding more sprites does not necessarily increase GPU requirements.
* Improved game startup performance when using a large amount of technologies with deep dependency trees (it's now 67,000 times faster).
* Optimized rendering of logistic overlay when zoomed in to map. ([https://forums.factorio.com/60659 more])
* Optimized rendering of turret ranges when zoomed in to map. ([https://forums.factorio.com/58991 more])
=== Changes ===

** Resource generation settings now have a much more dramatic effect. Increased the number of steps for each setting.
** Ore patches are slightly less frequent but richer.
** There will be a more balanced amount of resources within a large enough region.
** Many other small tweaks.
* Biter generation changed significantly:
** Biter richness slider removed, biter placement is only configured by size and frequency settings.
** Biter generation settings now have a much more dramatic effect. Increased the number of steps for each setting.
** Biter bases will increase in size, frequency and number of worms depending on the distance from player spawn.
** Worm size increases depending on the distance from player spawn.
** Small biter bases are now closer to the player spawn.
** At large distances from player spawn, biter base frequency is lower than before but biter bases are larger.
** Other small tweaks.
* Terrain generation changed significantly:
** Water is generated as large lakes instead of swamps.
** Tile generation improved. Tile placement respects biomes better.
** More predictable cliff placement.
** Better controls in the map generator GUI for water, tiles and cliffs.
* New map terrain type selectable: Island. Launch the rocket with only a limited amount of resources available on the map.
* Default resolution of the game is now 1920x1080.
* Increased player reach from 6 to 10.
* Inserters are putting science packs to the lab even when there is no research in progress or when the research doesn't need that particular pack.
* Default_request_amount removed in all places where it was used. Default logistic request is 1 stack, unless changed by the setting "Default request is 1".

* Placing a tile will now clear any tile ghosts at that position. ([https://forums.factorio.com/59721 more])
* It is allowed to use unicode characters in save names.
* Recipes that have more ingredients than the assembling machine allows are now shown as red instead of not present when selecting the recipe.
* When the "Made in" row is shown in the recipe tooltip, player icon is added to the list when it is craftable by player.
* Increased ghost time to live of ghosts from 1 hour to 1 week.
* Since the catalysts have been tweaked, the kovarex enrichment process can now be used together with productivity module.
* Tile construction jobs are being handled by robots separately from entity building jobs, to prevent entity ghosts not being built due to large number of tile ghosts.
* Switched key bindings from key codes to scan codes. This solves an issue with bad default key bindings on layouts that are not similar to US QWERTY (ie. AZERTY).
* Armor no longer uses durability and all armor now has a stack size of 1.
* Manually putting modules into machines that are requesting modules from the logistic network will reduce the modules requested.
* Increased maximum train stop length from 50 to 100 characters so it can fit at least 3 tags in most cases.
* Items consumed by hand crafting are counted in item production statistics.
* Added --disable-migration-window command-line option to disable the "migrated content" gui.
* Removed tile properties debug overlay.
* Command-line map preview generator now shows biter nests.

* Removed Wood from the game (And raw wood renamed to Wood).
* Added rotation smoothing to biters.
* Chests and wooden power poles are no longer usable as fuel.
* Burner efficiency is set to 100% for all entities and fuel value is halved to simplify calculations. This should not change game balance.
* Removed the hardness/mining power mechanics, we just have a mining speed and mining time now.
* Manual mining speed times of various entities will differ a bit, but probably not in a noticeable way.
* Stone and other ore mining speed has been unified to be 1 (apart uranium ore, which is 2 and shown as 200% mining time)
* Mining drill speed is now shown in the form of <x>/s (0.25/s for burner mining drill, 0.5/s for electric mining drill), the relative mining speeds of the mining machines have been decreased a little so the numbers are rounded nicely (0.28 -> 0.25 and 0.525 -> 0.5).
* Renamed the whitelist and banlist to server-whitelist and server-banlist.
* Added server-adminlist that's used to determine which people are admins when hosting any multiplayer game. This is synced both ways when hosting any game.
* Removed "admins" from the multiplayer server-settings file - they're now handled through server-adminlist.
* "Z" (drop item) will drop single items into what ever entity is selected instead of only dropping on the ground.
* Stickers can by applied onto cars and tanks now.
* Changed the chat gray-out mechanism. It always greyed-out after 5 seconds to 70% alpha, and then stayed depending on the setting. Now it stays 100% and only greys out away in the last 2 seconds.
* Placing entities or paths removes tree stumps and biter corpses.
* Removed New Hope campaign.

Oil processing

2019-03-05T15:16:07Z

Khaylain: /* Petroleum gas production */ "speed up" changed to "sped up" for clarity

{{Languages}}
'''Oil processing''' is a large part of Factorio. Oil processing may refer to [[Oil processing (research)|the researched technology]], the recipe used in the [[oil refinery]], or the overall workings of oil.

== Overview ==
There are various recipes that can be used to process [[crude oil]] into its fractions. Its fraction ([[heavy oil]], [[light oil]] and [[petroleum gas]]) can also be cracked into each other. Their recipes and technology requirements can be seen below.

|}

== Setting up oil processing ==
[[Pumpjack]]s need to be placed on top of the middle of the oil well, which is highlighted with a green box when the pumpjack is held. Pumpjacks produce a certain amount of [[Crude oil]] per second, shown on the right, at the bottom of the information panel. Over time this value will decrease down to a minimum of 2 oil/s, so a pumpjack will provide unlimited oil but eventually at a very low rate.

Crude oil must be refined in an [[oil refinery]]. The oil refinery needs to have a recipe set (see above for available recipes). Once it is set and "alt-mode" is active, the input and output locations and the expected fluids are shown. The locations of these cannot be changed, only the entire machine can be rotated. The refinery will stop production of all products if one product output is full, so it should be ensured that the products are transported out of the refinery; any products that cannot be used should be (temporarily) stored in a [[storage tank]].

Once the process finishes, the player will be left with 3 products: [[heavy oil]], [[light oil]] and [[petroleum gas]]. Both heavy oil and light oil can be cracked to the next lower type in a [[chemical plant]] (recipe above). This is useful if the player has an abundance of one product, but is lacking another (a common problem).

=== Tips ===
* The [[circuit network]] can be used to easily control how much fluid gets used for each recipe, to ensure that the player always has enough. For examples on how to do this, see the [[Tutorial:Circuit network cookbook#Oil_Setups|circuit-network cookbook]].
* If you run your heavy oil pipe from the refineries past a lubricant-making chemical plant before sending it to the cracking chemical plants, you can be sure that the lubricant production will have priority over cracking.
* Solid fuel is most efficient when created from light oil. If the player has too much heavy oil, cracking it to light oil then making it into fuel is more efficient than making heavy oil into fuel directly.

=== Transporting fluids ===
There are many ways to move fluids in Factorio, they are listed below:

* [[Pipe]]s
* [[Fluid wagon]]s
* Loading the fluids into [[Barrel]]s and transporting them by [[Railway]] or the [[Logistic network]]

== Optimal Ratios ==
The optimal ratio is the ratio of production that ensures no waste of time or materials.

=== Petroleum gas production ===

For producing petroleum gas, the optimal advanced oil processing ratio is 10:1:7 (advanced oil processing : heavy oil cracking : light oil cracking). Using coal liquefaction, the ratio is 60:39:55 (coal liquefaction : heavy oil cracking : light oil cracking), and 12:8:11 is close enough.

The refining can be sped up with [[module]]s; to prevent jams or inactive buildings it is recommended to speed everything up evenly. When slowing the process down (by using [[productivity module]]s) you are better off experimenting on altering the ratio or the speed on certain buildings, since the default ratios given above only hold if all the structures involved run at the same speed and have 100% productivity (in other words, no bonuses).

Enemies

2019-03-05T01:46:36Z

Khaylain: Removed reference to only three types of worms in the first paragraph

{{Languages}}
'''Enemies''' (also commonly called '''biters''') are creatures that want to harm the [[player]]. They are the native inhabitants of the extraterrestrial world in the form of arthropods living in organic nests, coexisting with each other peacefully. They are encountered in three species: Biters, Spitters and Worms. The species are further distinguished in four stages of growth, and thus strength. Enemies and nests show up on the map as red dots.

== Achievements ==
Enemies are directly connected to the following achievements:
{{Achievement|it-stinks-and-they-dont-like-it}}
{{Achievement|steamrolled}}

==Creatures==
===Biters===
Biters are one of two main antagonists in the game. They come in four sizes: small, medium, big and behemoth. In the beginning of a game, there will only be the small ones. With increasing [[pollution]], they will become bigger, related to the enemy's [[#Evolution|evolution]]. As common sense may suggest, their method of attack is a straightforward charge to "bite" things.

|}

===Spitters===
'''Spitters''' are much like [[Enemies#Biters|Biters]] and only appear slightly later on in the game as the evolution factor increases. Their main difference from Biters is their ranged attack. The attack is unavoidable and always hits the intended target. It is also acid-based, and because most entities of the game have a much lower resistance to acid than other damage types (including [[turret]]s and [[armor]]), Spitters are effectively more potent against the player and his factories. Their behaviour and size classification are the same as with Biters, but their health is universally lower and they are resistant exclusively against explosives, with no physical resistance.

|}

===Worms===

The Worms are natural allies of Biters and Spitters and will attack the player if they get close enough with an attack similar to Spitters'. They act like static [[turret]]s and will not follow attackers. They rely on high damage, great range and splash damage to keep the player away from the Worms and the nests they protect, but either one of these advantages can be overcome. Unlike other enemies, they are also highly resistant to fire. They will spit acid at the player, which can also leave acidic puddles on the ground that can still damage players as well as slow them down.

Worms come in 4 sizes, their power increasing with size. Unlike Biters and Spitters, Big and Medium Worms are not influenced by the evolution factor, they can spawn at any size right from the beginning. They are not restricted to spawning close to [[Enemies#Spawners|nests]], either. The number and size of Worms spawning is instead influenced by the distance from the player's initial spawn point. The further away the player goes from the starting area, the more numerous and stronger the Worms become.

==Nests==

The spawn points of biters and spitters. While nests themselves are generally defenseless, the enemies they release over time effectively serve as a form of guards to distract the player and any nearby turrets, and are often accompanied by Worms. Nests exposed to pollution will use it to evolve the enemies they spawn, which may also result in an attack. Enemies not engaged in combat may seek out the nearest nest for protection.

The nests are highly resistant to fire and otherwise generally more resilient than a medium worm.

===Expansions===
Every 4-60 minutes, a group of 5-20 biters/spitters will leave their base to create a new base. This group will search for a suitable spot that's 3-7 chunks away from existing bases.
Once they have found a suitable spot, the group dies and forms a new nest or worm. Medium worms are only formed if the current evolution is higher than 0.3, and big worms are only formed if the current evolution is higher than 0.5. The game randomly chooses whether to form a new biter nest, spitter nest, small worm, or bigger worm if the evolution factor is high enough.

==Defense==
Biters will only aggressively engage the player's factory if the pollution cloud of the factory reaches a nest. The Nests consume pollution to develop the biters and produce additional ones before sending them to destroy the nearest source of pollution that they consume. The biters then proceed to their target over the shortest path possible, accounting for terrain, but not for player entities that could pose an obstacle (like [[Stone wall|walls]]).

If there is a clear path somewhere around those obstacles, the biters will attempt to go around. If there is no clear passage or a clear passage would mean deviating too far from the original course, the biters will attack whatever is in their way to go through. This can be exploited to an extent; creating mazes at regular intervals along a barrier can direct the biters through a gauntlet not dissimilar to Tower Defense.

However, if a biter comes in proximity of the player, [[turret]]s or [[radar]]s, it will prioritize these and attempt to immediately attack them instead, again trying to reach the new target over the shortest possible path with no too great detours, if possible.

==Evolution==
[[File:Evolution Biters.png|thumb|right|400px|Spawn chances of biters from biter spawners by evolution factor.]]
[[File:Evolution Spitters.png|thumb|right|400px|Spawn chances of spitters from spitter spawners by evolution factor.]]
[[File:Evolution Weights.png|thumb|right|400px|Weight graph of both spawners by evolution factor. The values shown are primarily for indicating when certain types start and stop spawning, for actual chances refer to the tables or other charts.]]
The evolution factor is a global variable that determines what kind of biters will be spawned. You can check the variable in the dev console via the following command (does not disable achievements):

/evolution

The evolution factor goes from 0 (not evolved at all) to 1 (maximal evolution). At the moment the evolution factor can only increase.

Besides choosing what kind of biter will be spawned, the evolution factor also influences the spawning interval. This interval (<code>spawning_cooldown</code> in the <code>enemy-spawner</code> definition) is interpolated between 360 (0 evolution) and 150 (1 evolution) game ticks (= 6 to 2.5 seconds).

=== Methods of increasing ===

The evolution factor is increased by three kinds of events:

* The passage of time very slightly increases the evolution factor.
* The global [[Pollution|pollution production]] increases the evolution factor.
* Destroying [[Enemies#Nests|nests]] significantly increases the evolution factor.

All these values are set in <code>game.map_settings.enemy_evolution</code>. From there they can be changed or modded.

The default settings are:

{| class="wikitable"
!Source per
!Variable in <code>enemy_evolution</code>
!Percent increase
|-
| [[Game-second|Second]] || <code>time_factor</code> || 0.0004%
|-
| 1000 Pollution Units || <code>pollution_factor</code> || 0.0015%
|-
| Destroyed enemy spawner || <code>destroy_factor</code> || 0.2%
|}

Pollution production is the total pollution produced by [[Pollution#Polluters|buildings]] per tick, not the pollution spreading on the map, so it is not reduced by trees or other absorbers.
e.g. : 15 burner mining drills produce 150 pollution per second, raising the evolution factor by 0.00000225 per tick.

The percentages are applied on the base of <code>1 - current_evolution_factor</code>. So for instance destroying enemy spawners in the beginning of the game results in increase of evolution factor by 0.005 (half a percent) while doing this when the evolution factor is 0.5 the increase is only 0.0025 (quarter a percent).

This also means that the evolution factor approaches 1 asymptotically - generally, increases past 0.9 or so are ''very'' slow and the number never actually reaches 1.0.

=== Spawn chances by evolution factor ===

The probability charts show the chances of each type of biter/spitter for each spawner at all evolution levels.

<div id="evoChecker"></div>

=== Advanced: Evolution factor components and computation ===
<div class="toccolours mw-collapsible mw-collapsed" style="width:calc(100%-400px); overflow:auto;">
This section has charts plotting the individual evolution factor components and discusses possibilities for manually estimating the evolution factor.
<div class="mw-collapsible-content">

[[File:Evolution_factor_by_time.png|400px|thumb|right|1. Single-component evolution factor increase with time]]
[[File:Evolution_factor_by_pollution.png|400px|thumb|right|2. Single-component evolution factor increase with pollution]]
[[File:Evolution_factor_by_spawners.png|400px|thumb|right|3. Single-component evolution factor increase with destroyed spawners]]

'''Notes'''

*All charts end at approximately an evolution factor of 0.99.

*To simplify calculation, the time and pollution charts are calculated using steps of 1,000 seconds / 1,000,000 pollution units - in both cases 1,000 times larger than the unit the game uses for the calculation. Because of the recursive nature of the calculation, this makes the values in the charts somewhat '''higher''' than those the game would obtain in the same calculation; however, the difference is fairly minimal (less than 1 percentage point). The spawners chart is calculated 1-to-1 and therefore accurate.

*While time passed is shown on save files and spawners destroyed can be retrieved from player statistics, the game does not currently report the total pollution released by the player. Also, none of the well-known Factorio calculators show pollution generated by a particular factory. Therefore, to make use of the pollution chart the player's pollution output would need to be manually estimated.

*Given that the game reports the actual evolution factor (console: <code>/evolution</code>) whenever the player wishes, these charts are intended primarily to help estimate the impact of planned base expansions and similar activities on the evolution factor's future development.

'''Comments'''

These charts (click to enlarge) represent the situation where each evolution factor component (time, pollution, destroyed spawners) is the ''only'' component contributing to the evolution factor in that entire game. They are therefore '''not realistic''', as in a typical game all three components will contribute, some at varying times and intensities.

Because of how contributions to the evolution factor (hereinafter, EF) are calculated (multiplied by <code>(1 - current EF)</code>), it is '''not''' possible to simply add the values indicated by these charts for a game's time passed, pollution generated, and / or spawners destroyed so far to retrieve the total evolution factor.

For example, if 20 hours have passed (single-component EF =~ 0.25), 10 million pollution units were released (single-component EF =~ 0.15), and 200 spawners were destroyed (single-component EF =~ 0.35), the actual evolution factor will '''not''' be (0.25 + 0.15 + 0.35 =) ~0.85.

However, the evolution factor will always be '''less''' than the sum of all individual components as indicated by these charts, and '''at least''' as high as the highest individual component. Thus, using the values from above, the EF will be ''at least'' 0.35 and ''less than'' 0.85. A smarter approach is required to compute the amount of pollution released.

'''Computation of actual evolution factor'''

The actual EF can be computed as follow :

<code> 1 - EF = (1 - E[t]) * (1 - E[p]) * (1 - E[s])</code>, where ''E[t]'', ''E[p]'', and ''E[s]'' are the single-component values from the pollution, time, and spawner charts, in that order.

A key observation in understanding where this formula comes from is that each increpmental change of the evolution factor is effectively a multiplication of <code>1 - EF</code> by a constant (depending on the nature of the change). For example, an other way of saying that killing a biter nest augment evolution by 0.2% of <code>1 - EF</code>, is to say that killing a biter nest multiplies <code>1 - EF</code> by 0.998.

So like multiplication, evolution is, barring rounding errors, associative and commutative. The commutativity means that the order in which you make actions increasing evolution do not matter, and along the assossiativity grounds the formula above.

That knowledge can also be applied to compute the above charts exactly, or to compute a component of evolution without having to refer to the chart at all. For example, pollution as a function of time only is <code>1 - 0.999996 ^ t</code> where t is the time in seconds.

For the values from above, we can deduce the evolution factor <code>1 - EF = (1 - 0.25) * (1 - 0.15) * (1 - 0.35) = 0.75 * 0.85 * 0.35 = 0.41</code>, which gives an evolution factor of <code>0.59</code>.

This formula can also be used to estimate impact of future player activities on the EF : a set of actions that is known to bring the evolution factor of a world from 0 to EF(2) (eg using the above chart and formula) will bring it from EF(1) to <code>1 - (1-EF(1)) * (1-EF(2))</code>

For example, if the player planned to spend the next 20 hours building up their base, releasing 10 million pollution and destroying 200 spawners in the meantime (i.e., the same numbers as in the example above), and the EF at the start of the project were, say, 0.55, then the estimated EF at project end will be <code>1 - (1 - 0.55) * (1 - 0.59) = 0.81</code>.

* Added shortcut bar that allows quick access to certain game features, such as toggling alt mode, creating blueprints, or turning off personal roboport
* New gui style with final version of some parts of the GUI (More in Gui section)
* Added clipboard functionality. (Control + C, Control + X, Control + V activate appropriate tools) Shift + mouse wheel allows to cycle the clipboard history.
* Added undo functionality (Control + Z). Supports manual entity building and by blueprints and manual mining and usage of deconstruction planner.
* Reworked the Map Editor so it's now part of the standard game and can be toggled at will using the '/editor' command.
* Support for mod synchronisation when joining multiplayer game. Works as long as the used mods are on the mod portal.
* Fight changes. Enemy projectiles are dodgeable and slowdown/damage the target over time. They also leave splashes on ground that have the same effect.

* Added Passenger present and Passenger not present wait condition to the train conditions.
* If building of entity/blueprint fails, the reason of it is pinged as flying text.
* Map pings. Ctrl+Alt+click on the map to show a ping in all players maps at that location.
* Basic image tags format is [img=<image path>] where image path can use item, entity, technology, recipe, item-group, fluid tile, virtual signal achievement or utility icon.
** For example [img=item/iron-plate] or [img=item.iron-plate]. The "." instead of "/" usage is to make it usable in save names.
** Additionally, items/entities/technologies/recipe/item-group/fluid/tile/virtual signal or achievement can be linked directly by [item=iron-plate], [recipe=iron-plate], or [entity=small-biter] to provide tooltip for the appropriate object.
* Blueprint/special item tags.
** Shift clicking the icon in chat will create an item and place it in the cursor.
** Format is [special-item=blueprint string], eg: [special-item=0eNp1jtEKwjAMRX9l5rnCxkShvyIi3YxboU1Lm4lj9N9N54sv5iFwL/eeZIPBLRiTJQa9gR0DZdDXDbKdyLjq8RoRNFhGDwrI+Ko4GcoxJD4O6BiKAksPfIPuyk0BElu2+CXtYr3T4gdMEvjHUBBDllqgelVQrYJVdqnE/br+eVaBM1ITb0bnQvNMwTc8YzPOhiZ0YTpI5oUp78BL33YnmbY/l/IBb4pSQQ==].
** These tags also work with deconstruction and upgrade planners.
* Map ping tags: Created by shift-clicking the ground/map when the chat is open. Format is [gps=x,y], eg [gps=10,30] will show a map ping in all players maps at location 10,30.
** Clicking the icon in chat will open the map on the specified location.
* Font tags: Format is [font=debug-mono]mono text[/font].
* Color tags: Format is [color=1,0,0]red text[/font]
* Fast replacing pipes by pipes to ground similar to underground belts.
* When multiple versions of the same mod are installed you can select which version you want to use.

* Added 250 and 1000 hours precision intervals into statistics.
* Using deconstruction planner is incorporated in the latency hiding.
* Changed personal roboports so they won't send construction robots if you're driving in a vehicle that they can't keep up with or if in a train in automatic mode.
* Added an option to ignore mouse events when using accessibility zoom feature on macOS.
* Added support to change multiplayer config settings runtime.

* Added the Admin GUI (openable through /admin in the console) to manage multiplayer players.
* Landfill can be built by robots and be included in blueprints.
* Blueprint items taken from blueprint library will not move to player inventory when Q is pressed, but can be moved to any slot explicitly. (Same as with clipboard items)
* When selecting any item to the cursor from some of the player inventories. As long as the item is being held, hand icon is shown on the slot it was taken from. The hand prevents any other item to be inserted into the slot as long as the player cursor isn't cleared.
* When holding radar in cursor, area covered by existing radars is also highlighted on minimap.
* Configurable (in gui), the count of rolling stocks shown in the train visualization.

=== Graphics ===
* New graphics for:
** accumulator
** biters, spitters, worms, spawners
** chests
** electric poles and substation
** map edge transitions
** rocket silo
** transport belts, underground belts, splitters and transport belt circuit connector
** trees
** turrets (gun, flamethrower and laser)
** walls and gates
* laser turrets, personal laser defense and distractor robots now use new laser beams.
* Highlighting inserters that would interact with selected/previewed entity.
* Showing shield bars above health bar for relevant entities.
* Single vertical pipe is shorter.
=== Gui ===
* New final versions of several important GUI screens (Quick bar, Train Schedule, Load/Save Game, Settings, Map Generator, Research, Mods)
** Other screens than the mentioned ones (more than 100) have inconsistencies and will be updated in future minor updates.
* The quickbar is no longer an inventory, instead it can only hold shortcuts it items in inventory or blueprint library.
** The quickbar now has 10 pages of shortcuts.
** Player inventory increased by 20 slots to compensate. Toolbelt research further increases the player inventory.
* In the map, station and tag selection is now visualized by the standard Factorio selection box graphics instead of highlighting.
* Added interface option: When selecting a buildable item from the quickbar or when using the pipette tool, if you have no items of that type, a ghost will be placed in the cursor instead.
* When something is not buildable (manual or blueprint building), the reason of why it isn't buildable is shown as flying text over the cursor when the build is attempted.
* Only compatible results of a furnace are manually placeable in the result slot. (Mainly to avoid confusion of new players)
=== Optimisations ===
* Modernized and optimized rendering backend. The game now uses DirectX 11 or OpenGL 3.3 Core and requires DirectX 10 class graphics card.
* DirectX backend doesn't keep backup of all sprites in RAM anymore.
* Added high quality texture compression to reduce amount of video memory consumed by the game and increase overall rendering performance.
* Added texture streaming so that adding more sprites does not necessarily increase GPU requirements.
* Improved game startup performance when using a large amount of technologies with deep dependency trees (it's now 67,000 times faster).
* Optimized rendering of logistic overlay when zoomed in to map. ([https://forums.factorio.com/60659 more])
* Optimized rendering of turret ranges when zoomed in to map. ([https://forums.factorio.com/58991 more])
=== Changes ===

** Resource generation settings now have a much more dramatic effect. Increased the number of steps for each setting.
** Ore patches are slightly less frequent but richer.
** There will be a more balanced amount of resources within a large enough region.
** Many other small tweaks.

** Biter richness slider removed, biter placement is only configured by size and frequency settings.
** Biter generation settings now have a much more dramatic effect. Increased the number of steps for each setting.
** Biter bases will increase in size, frequency and number of worms depending on the distance from player spawn.
** Worm size increases depending on the distance from player spawn.
** Small biter bases are now closer to the player spawn.
** At large distances from player spawn, biter base frequency is lower than before but biter bases are larger.
** Other small tweaks.
* Terrain generation changed significantly:
** Water is generated as large lakes instead of swamps.
** Tile generation improved. Tile placement respects biomes better.
** More predictable cliff placement.
** Better controls in the map generator GUI for water, tiles and cliffs.
* New map terrain type selectable: Island. Launch the rocket with only a limited amount of resources available on the map.
* Default resolution of the game is now 1920x1080.
* Increased player reach from 6 to 10.
* Inserters are putting science packs to the lab even when there is no research in progress or when the research doesn't need that particular pack.
* Default_request_amount removed in all places where it was used. Default logistic request is 1 stack, unless changed by the setting "Default request is 1".

* Placing a tile will now clear any tile ghosts at that position. ([https://forums.factorio.com/59721 more])
* It is allowed to use unicode characters in save names.
* Recipes that have more ingredients than the assembling machine allows are now shown as red instead of not present when selecting the recipe.
* When the "Made in" row is shown in the recipe tooltip, player icon is added to the list when it is craftable by player.
* Increased ghost time to live of ghosts from 1 hour to 1 week.
* Since the catalysts have been tweaked, the kovarex enrichment process can now be used together with productivity module.
* Tile construction jobs are being handled by robots separately from entity building jobs, to prevent entity ghosts not being built due to large number of tile ghosts.
* Switched key bindings from key codes to scan codes. This solves an issue with bad default key bindings on layouts that are not similar to US QWERTY (ie. AZERTY).
* Armor no longer uses durability and all armor now has a stack size of 1.
* Manually putting modules into machines that are requesting modules from the logistic network will reduce the modules requested.
* Increased maximum train stop length from 50 to 100 characters so it can fit at least 3 tags in most cases.
* Items consumed by hand crafting are counted in item production statistics.
* Added --disable-migration-window command-line option to disable the "migrated content" gui.
* Removed tile properties debug overlay.

* Removed Wood from the game (And raw wood renamed to Wood).
* Added rotation smoothing to biters.
* Chests and wooden power poles are no longer usable as fuel.
* Burner efficiency is set to 100% for all entities and fuel value is halved to simplify calculations. This should not change game balance.
* Removed the hardness/mining power mechanics, we just have a mining speed and mining time now.
* Manual mining speed times of various entities will differ a bit, but probably not in a noticeable way.
* Stone and other ore mining speed has been unified to be 1 (apart uranium ore, which is 2 and shown as 200% mining time)
* Mining drill speed is now shown in the form of <x>/s (0.25/s for burner mining drill, 0.5/s for electric mining drill), the relative mining speeds of the mining machines have been decreased a little so the numbers are rounded nicely (0.28 -> 0.25 and 0.525 -> 0.5).
* Renamed the whitelist and banlist to server-whitelist and server-banlist.
* Added server-adminlist that's used to determine which people are admins when hosting any multiplayer game. This is synced both ways when hosting any game.
* Removed "admins" from the multiplayer server-settings file - they're now handled through server-adminlist.
* "Z" (drop item) will drop single items into what ever entity is selected instead of only dropping on the ground.
* Stickers can by applied onto cars and tanks now.
* Changed the chat gray-out mechanism. It always greyed-out after 5 seconds to 70% alpha, and then stayed depending on the setting. Now it stays 100% and only greys out away in the last 2 seconds.
* Placing entities or paths removes tree stumps and biter corpses.
* Removed New Hope campaign.

== 0.17.0 ==
Date: 26. 02. 2019
=== Major Features ===
* New quickbar (more in Gui section)
* Added shortcut bar that allows quick access to certain game features, such as toggling alt mode, creating blueprints, or turning off personal roboport
* New gui style with final version of some parts of the GUI (More in Gui section)
* Added clipboard functionality. (Control + C, Control + X, Control + V activate appropriate tools) Shift + mouse wheel allows to cycle the clipboard history.
* Added undo functionality (Control + Z). Supports manual entity building and by blueprints and manual mining and usage of deconstruction planner.
* Reworked the Map Editor so it's now part of the standard game and can be toggled at will using the '/editor' command.
* Support for mod synchronisation when joining multiplayer game. Works as long as the used mods are on the mod portal.
* Fight changes. Enemy projectiles are dodgeable and slowdown/damage the target over time. They also leave splashes on ground that have the same effect.
* Rich text tags. These tags can be used almost anywhere: Chat, station names, save names, custom ui and probably a few places we didn't think of.
** They allow changing color, font, images and location/blueprint/armor/station/locomotive linking through chat. (More in features)
* Fluid mixing prevention. Actions that fail as they would lead to fluid mixing (like building a pipe, changing recipe, rotating etc.) produce an error message as flying text.
* Replaced First steps campaign with Introduction campaign, available from the Start campaign menu.
=== Features ===
* Trains can be blueprinted and deconstructed.
* Trains can be given temporary stations (by Control+clicking the map). Temporary station is automatically removed once the train departures from it.
* Train stops without conditions work as waypoints. (the train doesn't stop at those)
* Added Passenger present and Passenger not present wait condition to the train conditions.
* If building of entity/blueprint fails, the reason of it is pinged as flying text.
* Map pings. Ctrl+Alt+click on the map to show a ping in all players maps at that location.
* Basic image tags format is [img=<image path>] where image path can use item, entity, technology, recipe, item-group, fluid tile, virtual signal achievement or utility icon.
** For example [img=item/iron-plate] or [img=item.iron-plate]. The "." instead of "/" usage is to make it usable in save names.
** Additionally, items/entities/technologies/recipe/item-group/fluid/tile/virtual signal or achievement can be linked directly by [item=iron-plate], [recipe=iron-plate], or [entity=small-biter] to provide tooltip for the appropriate object.
* Blueprint/special item tags.
** Shift clicking the icon in chat will create an item and place it in the cursor.
** Format is [special-item=blueprint string], eg: [special-item=0eNp1jtEKwjAMRX9l5rnCxkShvyIi3YxboU1Lm4lj9N9N54sv5iFwL/eeZIPBLRiTJQa9gR0DZdDXDbKdyLjq8RoRNFhGDwrI+Ko4GcoxJD4O6BiKAksPfIPuyk0BElu2+CXtYr3T4gdMEvjHUBBDllqgelVQrYJVdqnE/br+eVaBM1ITb0bnQvNMwTc8YzPOhiZ0YTpI5oUp78BL33YnmbY/l/IBb4pSQQ==].
** These tags also work with deconstruction and upgrade planners.
* Map ping tags: Created by shift-clicking the ground/map when the chat is open. Format is [gps=x,y], eg [gps=10,30] will show a map ping in all players maps at location 10,30.
** Clicking the icon in chat will open the map on the specified location.
* Font tags: Format is [font=debug-mono]mono text[/font].
* Color tags: Format is [color=1,0,0]red text[/font]
* Fast replacing pipes by pipes to ground similar to underground belts.
* When multiple versions of the same mod are installed you can select which version you want to use.
* The sync mods with save/multiplayer game feature can now sync mod startup settings as well as mods.
* Added support to import and export permissions.
* Closing opened items (blueprint books/armor) now remembers what GUI you previously had open.
* Filter inserters can be set to whitelist or blacklist filters.
* Added belt immunity equipment.
* Added upgrade planner.

* Added RGB support for Logitech hardware.
* Robots can blow up cliffs.
* Wave defense scenario has been reworked to support multiple rounds and a procedurally generated map.
* Added a research queue that becomes available after the player has finished the game by launching a rocket with satellite.
=== Minor Features ===
* Warning icon for automated trains that are out of fuel.
* Added 250 and 1000 hours precision intervals into statistics.
* Using deconstruction planner is incorporated in the latency hiding.
* Changed personal roboports so they won't send construction robots if you're driving in a vehicle that they can't keep up with or if in a train in automatic mode.
* Added an option to ignore mouse events when using accessibility zoom feature on macOS.
* Added support to change multiplayer config settings runtime.
* Added support to edit the whitelist, banlist, and admin list when hosting a multiplayer game.
* Added the Admin GUI (openable through /admin in the console) to manage multiplayer players.
* Landfill can be built by robots and be included in blueprints.
* Blueprint items taken from blueprint library will not move to player inventory when Q is pressed, but can be moved to any slot explicitly. (Same as with clipboard items)
* When selecting any item to the cursor from some of the player inventories. As long as the item is being held, hand icon is shown on the slot it was taken from. The hand prevents any other item to be inserted into the slot as long as the player cursor isn't cleared.
* When holding radar in cursor, area covered by existing radars is also highlighted on minimap.
* Configurable (in gui), the count of rolling stocks shown in the train visualization.
* Added two levels of shallow water tiles (only placed by map editor, not generated). Enemies and vehicles can travel over shallow water.
=== Graphics ===
* New graphics for:
** accumulator
** biters, spitters, worms, spawners
** chests
** electric poles and substation
** map edge transitions
** rocket silo
** transport belts, underground belts, splitters and transport belt circuit connector
** trees
** turrets (gun, flamethrower and laser)
** walls and gates
* laser turrets, personal laser defense and distractor robots now use new laser beams.
* Highlighting inserters that would interact with selected/previewed entity.
* Showing shield bars above health bar for relevant entities.
* Single vertical pipe is shorter.
=== Gui ===
* New final versions of several important GUI screens (Quick bar, Train Schedule, Load/Save Game, Settings, Map Generator, Research, Mods)
** Other screens than the mentioned ones (more than 100) have inconsistencies and will be updated in future minor updates.
* The quickbar is no longer an inventory, instead it can only hold shortcuts it items in inventory or blueprint library.
** The quickbar now has 10 pages of shortcuts.
** Player inventory increased by 20 slots to compensate. Toolbelt research further increases the player inventory.
* In the map, station and tag selection is now visualized by the standard Factorio selection box graphics instead of highlighting.
* Added interface option: When selecting a buildable item from the quickbar or when using the pipette tool, if you have no items of that type, a ghost will be placed in the cursor instead.
* When something is not buildable (manual or blueprint building), the reason of why it isn't buildable is shown as flying text over the cursor when the build is attempted.
* Only compatible results of a furnace are manually placeable in the result slot. (Mainly to avoid confusion of new players)
=== Optimisations ===
* Modernized and optimized rendering backend. The game now uses DirectX 11 or OpenGL 3.3 Core and requires DirectX 10 class graphics card.
* DirectX backend doesn't keep backup of all sprites in RAM anymore.
* Added high quality texture compression to reduce amount of video memory consumed by the game and increase overall rendering performance.
* Added texture streaming so that adding more sprites does not necessarily increase GPU requirements.
* Improved game startup performance when using a large amount of technologies with deep dependency trees (it's now 67,000 times faster).
* Optimized rendering of logistic overlay when zoomed in to map. ([https://forums.factorio.com/60659 more])
* Optimized rendering of turret ranges when zoomed in to map. ([https://forums.factorio.com/58991 more])
=== Changes ===

** The starting area contains only iron, copper, coal and stone, in very predictable amounts. Uranium and oil are excluded from the starting area.
** Resource generation settings now have a much more dramatic effect. Increased the number of steps for each setting.
** Ore patches are slightly less frequent but richer.
** There will be a more balanced amount of resources within a large enough region.
** Many other small tweaks.
* Biter generation changed significantly:
** Biter richness slider removed, biter placement is only configured by size and frequency settings.
** Biter generation settings now have a much more dramatic effect. Increased the number of steps for each setting.
** Biter bases will increase in size, frequency and number of worms depending on the distance from player spawn.
** Worm size increases depending on the distance from player spawn.
** Small biter bases are now closer to the player spawn.
** At large distances from player spawn, biter base frequency is lower than before but biter bases are larger.
** Other small tweaks.
* Terrain generation changed significantly:
** Water is generated as large lakes instead of swamps.
** Tile generation improved. Tile placement respects biomes better.
** More predictable cliff placement.
** Better controls in the map generator GUI for water, tiles and cliffs.
* New map terrain type selectable: Island. Launch the rocket with only a limited amount of resources available on the map.
* Default resolution of the game is now 1920x1080.
* Increased player reach from 6 to 10.
* Inserters are putting science packs to the lab even when there is no research in progress or when the research doesn't need that particular pack.
* Default_request_amount removed in all places where it was used. Default logistic request is 1 stack, unless changed by the setting "Default request is 1".

* Placing a tile will now clear any tile ghosts at that position. ([https://forums.factorio.com/59721 more])
* It is allowed to use unicode characters in save names.
* Recipes that have more ingredients than the assembling machine allows are now shown as red instead of not present when selecting the recipe.
* When the "Made in" row is shown in the recipe tooltip, player icon is added to the list when it is craftable by player.
* Increased ghost time to live of ghosts from 1 hour to 1 week.
* Since the catalysts have been tweaked, the kovarex enrichment process can now be used together with productivity module.
* Tile construction jobs are being handled by robots separately from entity building jobs, to prevent entity ghosts not being built due to large number of tile ghosts.
* Switched key bindings from key codes to scan codes. This solves an issue with bad default key bindings on layouts that are not similar to US QWERTY (ie. AZERTY).
* Armor no longer uses durability and all armor now has a stack size of 1.
* Manually putting modules into machines that are requesting modules from the logistic network will reduce the modules requested.
* Increased maximum train stop length from 50 to 100 characters so it can fit at least 3 tags in most cases.
* Items consumed by hand crafting are counted in item production statistics.
* Added --disable-migration-window command-line option to disable the "migrated content" gui.
* Removed tile properties debug overlay.
* Command-line map preview generator now shows biter nests.
* Items sent in a rocket are counted in item production statistics. ([https://forums.factorio.com/62606 more])
* Removed pickaxes and replaced them with research effects.
* Removed Wood from the game (And raw wood renamed to Wood).
* Added rotation smoothing to biters.
* Chests and wooden power poles are no longer usable as fuel.
* Burner efficiency is set to 100% for all entities and fuel value is halved to simplify calculations. This should not change game balance.
* Removed the hardness/mining power mechanics, we just have a mining speed and mining time now.
* Manual mining speed times of various entities will differ a bit, but probably not in a noticeable way.
* Stone and other ore mining speed has been unified to be 1 (apart uranium ore, which is 2 and shown as 200% mining time)
* Mining drill speed is now shown in the form of <x>/s (0.25/s for burner mining drill, 0.5/s for electric mining drill), the relative mining speeds of the mining machines have been decreased a little so the numbers are rounded nicely (0.28 -> 0.25 and 0.525 -> 0.5).
* Renamed the whitelist and banlist to server-whitelist and server-banlist.
* Added server-adminlist that's used to determine which people are admins when hosting any multiplayer game. This is synced both ways when hosting any game.
* Removed "admins" from the multiplayer server-settings file - they're now handled through server-adminlist.
* "Z" (drop item) will drop single items into what ever entity is selected instead of only dropping on the ground.
* Stickers can by applied onto cars and tanks now.
* Changed the chat gray-out mechanism. It always greyed-out after 5 seconds to 70% alpha, and then stayed depending on the setting. Now it stays 100% and only greys out away in the last 2 seconds.
* Placing entities or paths removes tree stumps and biter corpses.
* Removed New Hope campaign.

== 0.17.0 ==
Date: 26. 02. 2019
=== Major Features ===
* New quickbar (more in Gui section)
* Added shortcut bar that allows quick access to certain game features, such as toggling alt mode, creating blueprints, or turning off personal roboport
* New gui style with final version of some parts of the GUI (More in Gui section)
* Added clipboard functionality. (Control + C, Control + X, Control + V activate appropriate tools) Shift + mouse wheel allows to cycle the clipboard history.
* Added undo functionality (Control + Z). Supports manual entity building and by blueprints and manual mining and usage of deconstruction planner.
* Reworked the Map Editor so it's now part of the standard game and can be toggled at will using the '/editor' command.
* Support for mod synchronisation when joining multiplayer game. Works as long as the used mods are on the mod portal.
* Fight changes. Enemy projectiles are dodgeable and slowdown/damage the target over time. They also leave splashes on ground that have the same effect.
* Rich text tags. These tags can be used almost anywhere: Chat, station names, save names, custom ui and probably a few places we didn't think of.
** They allow changing color, font, images and location/blueprint/armor/station/locomotive linking through chat. (More in features)
* Fluid mixing prevention. Actions that fail as they would lead to fluid mixing (like building a pipe, changing recipe, rotating etc.) produce an error message as flying text.
* Replaced First steps campaign with Introduction campaign, available from the Start campaign menu.
=== Features ===
* Trains can be blueprinted and deconstructed.
* Trains can be given temporary stations (by Control+clicking the map). Temporary station is automatically removed once the train departures from it.
* Train stops without conditions work as waypoints. (the train doesn't stop at those)
* Added Passenger present and Passenger not present wait condition to the train conditions.
* If building of entity/blueprint fails, the reason of it is pinged as flying text.
* Map pings. Ctrl+Alt+click on the map to show a ping in all players maps at that location.
* Basic image tags format is [img=<image path>] where image path can use item, entity, technology, recipe, item-group, fluid tile, virtual signal achievement or utility icon.
** For example [img=item/iron-plate] or [img=item.iron-plate]. The "." instead of "/" usage is to make it usable in save names.
** Additionally, items/entities/technologies/recipe/item-group/fluid/tile/virtual signal or achievement can be linked directly by [item=iron-plate], [recipe=iron-plate], or [entity=small-biter] to provide tooltip for the appropriate object.
* Blueprint/special item tags.
** Shift clicking the icon in chat will create an item and place it in the cursor.
** Format is [special-item=blueprint string], eg: [special-item=0eNp1jtEKwjAMRX9l5rnCxkShvyIi3YxboU1Lm4lj9N9N54sv5iFwL/eeZIPBLRiTJQa9gR0DZdDXDbKdyLjq8RoRNFhGDwrI+Ko4GcoxJD4O6BiKAksPfIPuyk0BElu2+CXtYr3T4gdMEvjHUBBDllqgelVQrYJVdqnE/br+eVaBM1ITb0bnQvNMwTc8YzPOhiZ0YTpI5oUp78BL33YnmbY/l/IBb4pSQQ==].
** These tags also work with deconstruction and upgrade planners.
* Map ping tags: Created by shift-clicking the ground/map when the chat is open. Format is [gps=x,y], eg [gps=10,30] will show a map ping in all players maps at location 10,30.
** Clicking the icon in chat will open the map on the specified location.
* Font tags: Format is [font=debug-mono]mono text[/font].
* Color tags: Format is [color=1,0,0]red text[/font]
* Fast replacing pipes by pipes to ground similar to underground belts.
* When multiple versions of the same mod are installed you can select which version you want to use.
* The sync mods with save/multiplayer game feature can now sync mod startup settings as well as mods.
* Added support to import and export permissions.
* Closing opened items (blueprint books/armor) now remembers what GUI you previously had open.
* Filter inserters can be set to whitelist or blacklist filters.
* Added belt immunity equipment.
* Added upgrade planner.
* Added steam networking support for steam users.
* Added RGB support for Logitech hardware.
* Robots can blow up cliffs.
* Wave defense scenario has been reworked to support multiple rounds and a procedurally generated map.
* Added a research queue that becomes available after the player has finished the game by launching a rocket with satellite.
=== Minor Features ===
* Warning icon for automated trains that are out of fuel.
* Added 250 and 1000 hours precision intervals into statistics.
* Using deconstruction planner is incorporated in the latency hiding.
* Changed personal roboports so they won't send construction robots if you're driving in a vehicle that they can't keep up with or if in a train in automatic mode.
* Added an option to ignore mouse events when using accessibility zoom feature on macOS.
* Added support to change multiplayer config settings runtime.
* Added support to edit the whitelist, banlist, and admin list when hosting a multiplayer game.
* Added the Admin GUI (openable through /admin in the console) to manage multiplayer players.
* Landfill can be built by robots and be included in blueprints.
* Blueprint items taken from blueprint library will not move to player inventory when Q is pressed, but can be moved to any slot explicitly. (Same as with clipboard items)
* When selecting any item to the cursor from some of the player inventories. As long as the item is being held, hand icon is shown on the slot it was taken from. The hand prevents any other item to be inserted into the slot as long as the player cursor isn't cleared.
* When holding radar in cursor, area covered by existing radars is also highlighted on minimap.
* Configurable (in gui), the count of rolling stocks shown in the train visualization.
* Added two levels of shallow water tiles (only placed by map editor, not generated). Enemies and vehicles can travel over shallow water.
=== Graphics ===
* New graphics for:
** accumulator
** biters, spitters, worms, spawners
** chests
** electric poles and substation
** map edge transitions
** rocket silo
** transport belts, underground belts, splitters and transport belt circuit connector
** trees
** turrets (gun, flamethrower and laser)
** walls and gates
* laser turrets, personal laser defense and distractor robots now use new laser beams.
* Highlighting inserters that would interact with selected/previewed entity.
* Showing shield bars above health bar for relevant entities.
* Single vertical pipe is shorter.
=== Gui ===
* New final versions of several important GUI screens (Quick bar, Train Schedule, Load/Save Game, Settings, Map Generator, Research, Mods)
** Other screens than the mentioned ones (more than 100) have inconsistencies and will be updated in future minor updates.
* The quickbar is no longer an inventory, instead it can only hold shortcuts it items in inventory or blueprint library.
** The quickbar now has 10 pages of shortcuts.
** Player inventory increased by 20 slots to compensate. Toolbelt research further increases the player inventory.
* In the map, station and tag selection is now visualized by the standard Factorio selection box graphics instead of highlighting.
* Added interface option: When selecting a buildable item from the quickbar or when using the pipette tool, if you have no items of that type, a ghost will be placed in the cursor instead.
* When something is not buildable (manual or blueprint building), the reason of why it isn't buildable is shown as flying text over the cursor when the build is attempted.
* Only compatible results of a furnace are manually placeable in the result slot. (Mainly to avoid confusion of new players)
=== Optimisations ===
* Modernized and optimized rendering backend. The game now uses DirectX 11 or OpenGL 3.3 Core and requires DirectX 10 class graphics card.
* DirectX backend doesn't keep backup of all sprites in RAM anymore.
* Added high quality texture compression to reduce amount of video memory consumed by the game and increase overall rendering performance.
* Added texture streaming so that adding more sprites does not necessarily increase GPU requirements.
* Improved game startup performance when using a large amount of technologies with deep dependency trees (it's now 67,000 times faster).
* Optimized rendering of logistic overlay when zoomed in to map. ([https://forums.factorio.com/60659 more])
* Optimized rendering of turret ranges when zoomed in to map. ([https://forums.factorio.com/58991 more])
=== Changes ===
* Resource generation changed significantly:
** The starting area contains only iron, copper, coal and stone, in very predictable amounts. Uranium and oil are excluded from the starting area.
** Resource generation settings now have a much more dramatic effect. Increased the number of steps for each setting.
** Ore patches are slightly less frequent but richer.
** There will be a more balanced amount of resources within a large enough region.
** Many other small tweaks.
* Biter generation changed significantly:
** Biter richness slider removed, biter placement is only configured by size and frequency settings.
** Biter generation settings now have a much more dramatic effect. Increased the number of steps for each setting.
** Biter bases will increase in size, frequency and number of worms depending on the distance from player spawn.
** Worm size increases depending on the distance from player spawn.
** Small biter bases are now closer to the player spawn.
** At large distances from player spawn, biter base frequency is lower than before but biter bases are larger.
** Other small tweaks.
* Terrain generation changed significantly:
** Water is generated as large lakes instead of swamps.

* Added rotation smoothing to biters.
* Chests and wooden power poles are no longer usable as fuel.
* Burner efficiency is set to 100% for all entities and fuel value is halved to simplify calculations. This should not change game balance.

* Manual mining speed times of various entities will differ a bit, but probably not in a noticeable way.
* Stone and other ore mining speed has been unified to be 1 (apart uranium ore, which is 2 and shown as 200% mining time)
* Mining drill speed is now shown in the form of <x>/s (0.25/s for burner mining drill, 0.5/s for electric mining drill), the relative mining speeds of the mining machines have been decreased a little so the numbers are rounded nicely (0.28 -> 0.25 and 0.525 -> 0.5).
* Renamed the whitelist and banlist to server-whitelist and server-banlist.
* Added server-adminlist that's used to determine which people are admins when hosting any multiplayer game. This is synced both ways when hosting any game.
* Removed "admins" from the multiplayer server-settings file - they're now handled through server-adminlist.
* "Z" (drop item) will drop single items into what ever entity is selected instead of only dropping on the ground.
* Stickers can by applied onto cars and tanks now.
* Changed the chat gray-out mechanism. It always greyed-out after 5 seconds to 70% alpha, and then stayed depending on the setting. Now it stays 100% and only greys out away in the last 2 seconds.
* Placing entities or paths removes tree stumps and biter corpses.
* Removed New Hope campaign.

Laser turret

2019-03-01T13:48:51Z

Khaylain: /* History */ Added graphical changes from 0.17.0 to history segment

{{Languages}}
{{:Infobox:Laser turret}}

Laser turrets are an advanced defense building with a longer range, infinite ammo, good damage and use [[Electric system|electricity]] to operate (and a smaller amount of energy when idle). By dealing '''laser damage''', they don't face any resistances ([[enemies]] receive full damage) but have a lower rate of fire than gun turrets. Each shot costs 800kJ of energy; as the shooting speed increases through upgrades, so too does the power required to keep firing.

Using laser turrets to ward off attacks can cause electricity usage spikes, these can be offset by using [[accumulator]]s (or [[Storage_tank#Usage_as_.22Energy-tank.22|steam storage]] and excess [[steam turbine]]s).

== 0.17.0 ==
Date: 26. 02. 2019
=== Major Features ===
* New quickbar (more in Gui section)
* Added shortcut bar that allows quick access to certain game features, such as toggling alt mode, creating blueprints, or turning off personal roboport
* New gui style with final version of some parts of the GUI (More in Gui section)
* Added clipboard functionality. (Control + C, Control + X, Control + V activate appropriate tools) Shift + mouse wheel allows to cycle the clipboard history.
* Added undo functionality (Control + Z). Supports manual entity building and by blueprints and manual mining and usage of deconstruction planner.
* Reworked the Map Editor so it's now part of the standard game and can be toggled at will using the '/editor' command.
* Support for mod synchronisation when joining multiplayer game. Works as long as the used mods are on the mod portal.
* Fight changes. Enemy projectiles are dodgeable and slowdown/damage the target over time. They also leave splashes on ground that have the same effect.
* Rich text tags. These tags can be used almost anywhere: Chat, station names, save names, custom ui and probably a few places we didn't think of.
** They allow changing color, font, images and location/blueprint/armor/station/locomotive linking through chat. (More in features)
* Fluid mixing prevention. Actions that fail as they would lead to fluid mixing (like building a pipe, changing recipe, rotating etc.) produce an error message as flying text.
* Replaced First steps campaign with Introduction campaign, available from the Start campaign menu.
=== Features ===
* Trains can be blueprinted and deconstructed.
* Trains can be given temporary stations (by Control+clicking the map). Temporary station is automatically removed once the train departures from it.
* Train stops without conditions work as waypoints. (the train doesn't stop at those)
* Added Passenger present and Passenger not present wait condition to the train conditions.
* If building of entity/blueprint fails, the reason of it is pinged as flying text.
* Map pings. Ctrl+Alt+click on the map to show a ping in all players maps at that location.
* Basic image tags format is [img=<image path>] where image path can use item, entity, technology, recipe, item-group, fluid tile, virtual signal achievement or utility icon.
** For example [img=item/iron-plate] or [img=item.iron-plate]. The "." instead of "/" usage is to make it usable in save names.
** Additionally, items/entities/technologies/recipe/item-group/fluid/tile/virtual signal or achievement can be linked directly by [item=iron-plate], [recipe=iron-plate], or [entity=small-biter] to provide tooltip for the appropriate object.
* Blueprint/special item tags.
** Shift clicking the icon in chat will create an item and place it in the cursor.
** Format is [special-item=blueprint string], eg: [special-item=0eNp1jtEKwjAMRX9l5rnCxkShvyIi3YxboU1Lm4lj9N9N54sv5iFwL/eeZIPBLRiTJQa9gR0DZdDXDbKdyLjq8RoRNFhGDwrI+Ko4GcoxJD4O6BiKAksPfIPuyk0BElu2+CXtYr3T4gdMEvjHUBBDllqgelVQrYJVdqnE/br+eVaBM1ITb0bnQvNMwTc8YzPOhiZ0YTpI5oUp78BL33YnmbY/l/IBb4pSQQ==].
** These tags also work with deconstruction and upgrade planners.
* Map ping tags: Created by shift-clicking the ground/map when the chat is open. Format is [gps=x,y], eg [gps=10,30] will show a map ping in all players maps at location 10,30.
** Clicking the icon in chat will open the map on the specified location.
* Font tags: Format is [font=debug-mono]mono text[/font].
* Color tags: Format is [color=1,0,0]red text[/font]
* Fast replacing pipes by pipes to ground similar to underground belts.
* When multiple versions of the same mod are installed you can select which version you want to use.
* The sync mods with save/multiplayer game feature can now sync mod startup settings as well as mods.
* Added support to import and export permissions.
* Closing opened items (blueprint books/armor) now remembers what GUI you previously had open.
* Filter inserters can be set to whitelist or blacklist filters.
* Added belt immunity equipment.
* Added upgrade planner.
* Added steam networking support for steam users.
* Added RGB support for Logitech hardware.
* Robots can blow up cliffs.
* Wave defense scenario has been reworked to support multiple rounds and a procedurally generated map.
* Added a research queue that becomes available after the player has finished the game by launching a rocket with satellite.
=== Minor Features ===
* Warning icon for automated trains that are out of fuel.
* Added 250 and 1000 hours precision intervals into statistics.
* Using deconstruction planner is incorporated in the latency hiding.
* Changed personal roboports so they won't send construction robots if you're driving in a vehicle that they can't keep up with or if in a train in automatic mode.
* Added an option to ignore mouse events when using accessibility zoom feature on macOS.
* Added support to change multiplayer config settings runtime.
* Added support to edit the whitelist, banlist, and admin list when hosting a multiplayer game.
* Added the Admin GUI (openable through /admin in the console) to manage multiplayer players.
* Landfill can be built by robots and be included in blueprints.
* Blueprint items taken from blueprint library will not move to player inventory when Q is pressed, but can be moved to any slot explicitly. (Same as with clipboard items)
* When selecting any item to the cursor from some of the player inventories. As long as the item is being held, hand icon is shown on the slot it was taken from. The hand prevents any other item to be inserted into the slot as long as the player cursor isn't cleared.
* When holding radar in cursor, area covered by existing radars is also highlighted on minimap.
* Configurable (in gui), the count of rolling stocks shown in the train visualization.
* Added two levels of shallow water tiles (only placed by map editor, not generated). Enemies and vehicles can travel over shallow water.
=== Graphics ===
* New graphics for:
** accumulator
** biters, spitters, worms, spawners
** chests
** electric poles and substation
** map edge transitions
** rocket silo
** transport belts, underground belts, splitters and transport belt circuit connector
** trees
** turrets (gun, flamethrower and laser)
** walls and gates
* laser turrets, personal laser defense and distractor robots now use new laser beams.
* Highlighting inserters that would interact with selected/previewed entity.
* Showing shield bars above health bar for relevant entities.
* Single vertical pipe is shorter.
=== Gui ===
* New final versions of several important GUI screens (Quick bar, Train Schedule, Load/Save Game, Settings, Map Generator, Research, Mods)
** Other screens than the mentioned ones (more than 100) have inconsistencies and will be updated in future minor updates.
* The quickbar is no longer an inventory, instead it can only hold shortcuts it items in inventory or blueprint library.
** The quickbar now has 10 pages of shortcuts.
** Player inventory increased by 20 slots to compensate. Toolbelt research further increases the player inventory.
* In the map, station and tag selection is now visualized by the standard Factorio selection box graphics instead of highlighting.
* Added interface option: When selecting a buildable item from the quickbar or when using the pipette tool, if you have no items of that type, a ghost will be placed in the cursor instead.
* When something is not buildable (manual or blueprint building), the reason of why it isn't buildable is shown as flying text over the cursor when the build is attempted.
* Only compatible results of a furnace are manually placeable in the result slot. (Mainly to avoid confusion of new players)
=== Optimisations ===
* Modernized and optimized rendering backend. The game now uses DirectX 11 or OpenGL 3.3 Core and requires DirectX 10 class graphics card.
* DirectX backend doesn't keep backup of all sprites in RAM anymore.
* Added high quality texture compression to reduce amount of video memory consumed by the game and increase overall rendering performance.
* Added texture streaming so that adding more sprites does not necessarily increase GPU requirements.
* Improved game startup performance when using a large amount of technologies with deep dependency trees (it's now 67,000 times faster).
* Optimized rendering of logistic overlay when zoomed in to map. ([https://forums.factorio.com/60659 more])
* Optimized rendering of turret ranges when zoomed in to map. ([https://forums.factorio.com/58991 more])
=== Changes ===
* Resource generation changed significantly:
** The starting area contains only iron, copper, coal and stone, in very predictable amounts. Uranium and oil are excluded from the starting area.
** Resource generation settings now have a much more dramatic effect. Increased the number of steps for each setting.
** Ore patches are slightly less frequent but richer.
** There will be a more balanced amount of resources within a large enough region.
** Many other small tweaks.
* Biter generation changed significantly:
** Biter richness slider removed, biter placement is only configured by size and frequency settings.
** Biter generation settings now have a much more dramatic effect. Increased the number of steps for each setting.
** Biter bases will increase in size, frequency and number of worms depending on the distance from player spawn.
** Worm size increases depending on the distance from player spawn.
** Small biter bases are now closer to the player spawn.
** At large distances from player spawn, biter base frequency is lower than before but biter bases are larger.
** Other small tweaks.
* Terrain generation changed significantly:
** Water is generated as large lakes instead of swamps.
** Tile generation improved. Tile placement respects biomes better.
** More predictable cliff placement.
** Better controls in the map generator GUI for water, tiles and cliffs.
* New map terrain type selectable: Island. Launch the rocket with only a limited amount of resources available on the map.
* Default resolution of the game is now 1920x1080.
* Increased player reach from 6 to 10.
* Inserters are putting science packs to the lab even when there is no research in progress or when the research doesn't need that particular pack.
* Default_request_amount removed in all places where it was used. Default logistic request is 1 stack, unless changed by the setting "Default request is 1".
* All personal equipment stack sizes changed to 20.
* Placing a tile will now clear any tile ghosts at that position. ([https://forums.factorio.com/59721 more])
* It is allowed to use unicode characters in save names.
* Recipes that have more ingredients than the assembling machine allows are now shown as red instead of not present when selecting the recipe.
* When the "Made in" row is shown in the recipe tooltip, player icon is added to the list when it is craftable by player.
* Increased ghost time to live of ghosts from 1 hour to 1 week.
* Since the catalysts have been tweaked, the kovarex enrichment process can now be used together with productivity module.
* Tile construction jobs are being handled by robots separately from entity building jobs, to prevent entity ghosts not being built due to large number of tile ghosts.
* Switched key bindings from key codes to scan codes. This solves an issue with bad default key bindings on layouts that are not similar to US QWERTY (ie. AZERTY).
* Armor no longer uses durability and all armor now has a stack size of 1.
* Manually putting modules into machines that are requesting modules from the logistic network will reduce the modules requested.
* Increased maximum train stop length from 50 to 100 characters so it can fit at least 3 tags in most cases.
* Items consumed by hand crafting are counted in item production statistics.
* Added --disable-migration-window command-line option to disable the "migrated content" gui.
* Removed tile properties debug overlay.
* Command-line map preview generator now shows biter nests.
* Items sent in a rocket are counted in item production statistics. ([https://forums.factorio.com/62606 more])
* Removed pickaxes and replaced them with research effects.
* Removed Wood from the game (And raw wood renamed to Wood).
* Added rotation smoothing to biters.
* Chests and wooden power poles are no longer usable as fuel.
* Burner efficiency is set to 100% for all entities and fuel value is halved to simplify calculations. This should not change game balance.
* Removed the hardness/mining power mechanics, we just have a mining speed and mining time now.
* Manual mining speed times of various entities will differ a bit, but probably not in a noticeable way.

== 0.17.0 ==
Date: 26. 02. 2019
=== Major Features ===
* New quickbar (more in Gui section)
* Added shortcut bar that allows quick access to certain game features, such as toggling alt mode, creating blueprints, or turning off personal roboport
* New gui style with final version of some parts of the GUI (More in Gui section)
* Added clipboard functionality. (Control + C, Control + X, Control + V activate appropriate tools) Shift + mouse wheel allows to cycle the clipboard history.
* Added undo functionality (Control + Z). Supports manual entity building and by blueprints and manual mining and usage of deconstruction planner.
* Reworked the Map Editor so it's now part of the standard game and can be toggled at will using the '/editor' command.
* Support for mod synchronisation when joining multiplayer game. Works as long as the used mods are on the mod portal.
* Fight changes. Enemy projectiles are dodgeable and slowdown/damage the target over time. They also leave splashes on ground that have the same effect.
* Rich text tags. These tags can be used almost anywhere: Chat, station names, save names, custom ui and probably a few places we didn't think of.
** They allow changing color, font, images and location/blueprint/armor/station/locomotive linking through chat. (More in features)
* Fluid mixing prevention. Actions that fail as they would lead to fluid mixing (like building a pipe, changing recipe, rotating etc.) produce an error message as flying text.
* Replaced First steps campaign with Introduction campaign, available from the Start campaign menu.
=== Features ===
* Trains can be blueprinted and deconstructed.
* Trains can be given temporary stations (by Control+clicking the map). Temporary station is automatically removed once the train departures from it.
* Train stops without conditions work as waypoints. (the train doesn't stop at those)
* Added Passenger present and Passenger not present wait condition to the train conditions.
* If building of entity/blueprint fails, the reason of it is pinged as flying text.
* Map pings. Ctrl+Alt+click on the map to show a ping in all players maps at that location.
* Basic image tags format is [img=<image path>] where image path can use item, entity, technology, recipe, item-group, fluid tile, virtual signal achievement or utility icon.
** For example [img=item/iron-plate] or [img=item.iron-plate]. The "." instead of "/" usage is to make it usable in save names.
** Additionally, items/entities/technologies/recipe/item-group/fluid/tile/virtual signal or achievement can be linked directly by [item=iron-plate], [recipe=iron-plate], or [entity=small-biter] to provide tooltip for the appropriate object.
* Blueprint/special item tags.
** Shift clicking the icon in chat will create an item and place it in the cursor.
** Format is [special-item=blueprint string], eg: [special-item=0eNp1jtEKwjAMRX9l5rnCxkShvyIi3YxboU1Lm4lj9N9N54sv5iFwL/eeZIPBLRiTJQa9gR0DZdDXDbKdyLjq8RoRNFhGDwrI+Ko4GcoxJD4O6BiKAksPfIPuyk0BElu2+CXtYr3T4gdMEvjHUBBDllqgelVQrYJVdqnE/br+eVaBM1ITb0bnQvNMwTc8YzPOhiZ0YTpI5oUp78BL33YnmbY/l/IBb4pSQQ==].
** These tags also work with deconstruction and upgrade planners.
* Map ping tags: Created by shift-clicking the ground/map when the chat is open. Format is [gps=x,y], eg [gps=10,30] will show a map ping in all players maps at location 10,30.
** Clicking the icon in chat will open the map on the specified location.
* Font tags: Format is [font=debug-mono]mono text[/font].
* Color tags: Format is [color=1,0,0]red text[/font]
* Fast replacing pipes by pipes to ground similar to underground belts.
* When multiple versions of the same mod are installed you can select which version you want to use.
* The sync mods with save/multiplayer game feature can now sync mod startup settings as well as mods.
* Added support to import and export permissions.
* Closing opened items (blueprint books/armor) now remembers what GUI you previously had open.
* Filter inserters can be set to whitelist or blacklist filters.
* Added belt immunity equipment.
* Added upgrade planner.
* Added steam networking support for steam users.
* Added RGB support for Logitech hardware.
* Robots can blow up cliffs.
* Wave defense scenario has been reworked to support multiple rounds and a procedurally generated map.
* Added a research queue that becomes available after the player has finished the game by launching a rocket with satellite.
=== Minor Features ===
* Warning icon for automated trains that are out of fuel.
* Added 250 and 1000 hours precision intervals into statistics.
* Using deconstruction planner is incorporated in the latency hiding.
* Changed personal roboports so they won't send construction robots if you're driving in a vehicle that they can't keep up with or if in a train in automatic mode.
* Added an option to ignore mouse events when using accessibility zoom feature on macOS.
* Added support to change multiplayer config settings runtime.
* Added support to edit the whitelist, banlist, and admin list when hosting a multiplayer game.

* Blueprint items taken from blueprint library will not move to player inventory when Q is pressed, but can be moved to any slot explicitly. (Same as with clipboard items)
* When selecting any item to the cursor from some of the player inventories. As long as the item is being held, hand icon is shown on the slot it was taken from. The hand prevents any other item to be inserted into the slot as long as the player cursor isn't cleared.
* When holding radar in cursor, area covered by existing radars is also highlighted on minimap.
* Configurable (in gui), the count of rolling stocks shown in the train visualization.
* Added two levels of shallow water tiles (only placed by map editor, not generated). Enemies and vehicles can travel over shallow water.
=== Graphics ===

** accumulator
** biters, spitters, worms, spawners
** chests
** electric poles and substation
** map edge transitions
** rocket silo
** transport belts, underground belts, splitters and transport belt circuit connector
** trees
** turrets (gun, flamethrower and laser)
** walls and gates
* laser turrets, personal laser defense and distractor robots now use new laser beams.
* Highlighting inserters that would interact with selected/previewed entity.
* Showing shield bars above health bar for relevant entities.
* Single vertical pipe is shorter.
=== Gui ===
* New final versions of several important GUI screens (Quick bar, Train Schedule, Load/Save Game, Settings, Map Generator, Research, Mods)
** Other screens than the mentioned ones (more than 100) have inconsistencies and will be updated in future minor updates.
* The quickbar is no longer an inventory, instead it can only hold shortcuts it items in inventory or blueprint library.
** The quickbar now has 10 pages of shortcuts.
** Player inventory increased by 20 slots to compensate. Toolbelt research further increases the player inventory.
* In the map, station and tag selection is now visualized by the standard Factorio selection box graphics instead of highlighting.
* Added interface option: When selecting a buildable item from the quickbar or when using the pipette tool, if you have no items of that type, a ghost will be placed in the cursor instead.
* When something is not buildable (manual or blueprint building), the reason of why it isn't buildable is shown as flying text over the cursor when the build is attempted.
* Only compatible results of a furnace are manually placeable in the result slot. (Mainly to avoid confusion of new players)
=== Optimisations ===
* Modernized and optimized rendering backend. The game now uses DirectX 11 or OpenGL 3.3 Core and requires DirectX 10 class graphics card.
* DirectX backend doesn't keep backup of all sprites in RAM anymore.
* Added high quality texture compression to reduce amount of video memory consumed by the game and increase overall rendering performance.
* Added texture streaming so that adding more sprites does not necessarily increase GPU requirements.
* Improved game startup performance when using a large amount of technologies with deep dependency trees (it's now 67,000 times faster).
* Optimized rendering of logistic overlay when zoomed in to map. ([https://forums.factorio.com/60659 more])
* Optimized rendering of turret ranges when zoomed in to map. ([https://forums.factorio.com/58991 more])
=== Changes ===

** Resource generation settings now have a much more dramatic effect. Increased the number of steps for each setting.
** Ore patches are slightly less frequent but richer.
** There will be a more balanced amount of resources within a large enough region.
** Many other small tweaks.
* Biter generation changed significantly:
** Biter richness slider removed, biter placement is only configured by size and frequency settings.
** Biter generation settings now have a much more dramatic effect. Increased the number of steps for each setting.
** Biter bases will increase in size, frequency and number of worms depending on the distance from player spawn.
** Worm size increases depending on the distance from player spawn.
** Small biter bases are now closer to the player spawn.
** At large distances from player spawn, biter base frequency is lower than before but biter bases are larger.
** Other small tweaks.
* Terrain generation changed significantly:
** Water is generated as large lakes instead of swamps.
** Tile generation improved. Tile placement respects biomes better.
** More predictable cliff placement.
** Better controls in the map generator GUI for water, tiles and cliffs.
* New map terrain type selectable: Island. Launch the rocket with only a limited amount of resources available on the map.
* Default resolution of the game is now 1920x1080.
* Increased player reach from 6 to 10.
* Inserters are putting science packs to the lab even when there is no research in progress or when the research doesn't need that particular pack.
* Default_request_amount removed in all places where it was used. Default logistic request is 1 stack, unless changed by the setting "Default request is 1".

* Placing a tile will now clear any tile ghosts at that position. ([https://forums.factorio.com/59721 more])
* It is allowed to use unicode characters in save names.
* Recipes that have more ingredients than the assembling machine allows are now shown as red instead of not present when selecting the recipe.
* When the "Made in" row is shown in the recipe tooltip, player icon is added to the list when it is craftable by player.
* Increased ghost time to live of ghosts from 1 hour to 1 week.
* Since the catalysts have been tweaked, the kovarex enrichment process can now be used together with productivity module.
* Tile construction jobs are being handled by robots separately from entity building jobs, to prevent entity ghosts not being built due to large number of tile ghosts.
* Switched key bindings from key codes to scan codes. This solves an issue with bad default key bindings on layouts that are not similar to US QWERTY (ie. AZERTY).
* Armor no longer uses durability and all armor now has a stack size of 1.
* Manually putting modules into machines that are requesting modules from the logistic network will reduce the modules requested.
* Increased maximum train stop length from 50 to 100 characters so it can fit at least 3 tags in most cases.
* Items consumed by hand crafting are counted in item production statistics.
* Added --disable-migration-window command-line option to disable the "migrated content" gui.
* Removed tile properties debug overlay.
* Command-line map preview generator now shows biter nests.
* Items sent in a rocket are counted in item production statistics. ([https://forums.factorio.com/62606 more])
* Removed pickaxes and replaced them with research effects.
* Removed Wood from the game (And raw wood renamed to Wood).
* Added rotation smoothing to biters.
* Chests and wooden power poles are no longer usable as fuel.
* Burner efficiency is set to 100% for all entities and fuel value is halved to simplify calculations. This should not change game balance.
* Removed the hardness/mining power mechanics, we just have a mining speed and mining time now.
* Manual mining speed times of various entities will differ a bit, but probably not in a noticeable way.
* Stone and other ore mining speed has been unified to be 1 (apart uranium ore, which is 2 and shown as 200% mining time)
* Mining drill speed is now shown in the form of <x>/s (0.25/s for burner mining drill, 0.5/s for electric mining drill), the relative mining speeds of the mining machines have been decreased a little so the numbers are rounded nicely (0.28 -> 0.25 and 0.525 -> 0.5).
* Renamed the whitelist and banlist to server-whitelist and server-banlist.
* Added server-adminlist that's used to determine which people are admins when hosting any multiplayer game. This is synced both ways when hosting any game.
* Removed "admins" from the multiplayer server-settings file - they're now handled through server-adminlist.
* "Z" (drop item) will drop single items into what ever entity is selected instead of only dropping on the ground.
* Stickers can by applied onto cars and tanks now.
* Changed the chat gray-out mechanism. It always greyed-out after 5 seconds to 70% alpha, and then stayed depending on the setting. Now it stays 100% and only greys out away in the last 2 seconds.
* Placing entities or paths removes tree stumps and biter corpses.
* Removed New Hope campaign.

== 0.17.0 ==
Date: 26. 02. 2019
=== Major Features ===
* New quickbar (more in Gui section)
* Added shortcut bar that allows quick access to certain game features, such as toggling alt mode, creating blueprints, or turning off personal roboport
* New gui style with final version of some parts of the GUI (More in Gui section)
* Added clipboard functionality. (Control + C, Control + X, Control + V activate appropriate tools) Shift + mouse wheel allows to cycle the clipboard history.
* Added undo functionality (Control + Z). Supports manual entity building and by blueprints and manual mining and usage of deconstruction planner.
* Reworked the Map Editor so it's now part of the standard game and can be toggled at will using the '/editor' command.
* Support for mod synchronisation when joining multiplayer game. Works as long as the used mods are on the mod portal.
* Fight changes. Enemy projectiles are dodgeable and slowdown/damage the target over time. They also leave splashes on ground that have the same effect.
* Rich text tags. These tags can be used almost anywhere: Chat, station names, save names, custom ui and probably a few places we didn't think of.
** They allow changing color, font, images and location/blueprint/armor/station/locomotive linking through chat. (More in features)
* Fluid mixing prevention. Actions that fail as they would lead to fluid mixing (like building a pipe, changing recipe, rotating etc.) produce an error message as flying text.
* Replaced First steps campaign with Introduction campaign, available from the Start campaign menu.
=== Features ===
* Trains can be blueprinted and deconstructed.
* Trains can be given temporary stations (by Control+clicking the map). Temporary station is automatically removed once the train departures from it.
* Train stops without conditions work as waypoints. (the train doesn't stop at those)
* Added Passenger present and Passenger not present wait condition to the train conditions.
* If building of entity/blueprint fails, the reason of it is pinged as flying text.
* Map pings. Ctrl+Alt+click on the map to show a ping in all players maps at that location.
* Basic image tags format is [img=<image path>] where image path can use item, entity, technology, recipe, item-group, fluid tile, virtual signal achievement or utility icon.
** For example [img=item/iron-plate] or [img=item.iron-plate]. The "." instead of "/" usage is to make it usable in save names.
** Additionally, items/entities/technologies/recipe/item-group/fluid/tile/virtual signal or achievement can be linked directly by [item=iron-plate], [recipe=iron-plate], or [entity=small-biter] to provide tooltip for the appropriate object.
* Blueprint/special item tags.
** Shift clicking the icon in chat will create an item and place it in the cursor.
** Format is [special-item=blueprint string], eg: [special-item=0eNp1jtEKwjAMRX9l5rnCxkShvyIi3YxboU1Lm4lj9N9N54sv5iFwL/eeZIPBLRiTJQa9gR0DZdDXDbKdyLjq8RoRNFhGDwrI+Ko4GcoxJD4O6BiKAksPfIPuyk0BElu2+CXtYr3T4gdMEvjHUBBDllqgelVQrYJVdqnE/br+eVaBM1ITb0bnQvNMwTc8YzPOhiZ0YTpI5oUp78BL33YnmbY/l/IBb4pSQQ==].
** These tags also work with deconstruction and upgrade planners.
* Map ping tags: Created by shift-clicking the ground/map when the chat is open. Format is [gps=x,y], eg [gps=10,30] will show a map ping in all players maps at location 10,30.
** Clicking the icon in chat will open the map on the specified location.
* Font tags: Format is [font=debug-mono]mono text[/font].
* Color tags: Format is [color=1,0,0]red text[/font]
* Fast replacing pipes by pipes to ground similar to underground belts.
* When multiple versions of the same mod are installed you can select which version you want to use.
* The sync mods with save/multiplayer game feature can now sync mod startup settings as well as mods.
* Added support to import and export permissions.
* Closing opened items (blueprint books/armor) now remembers what GUI you previously had open.
* Filter inserters can be set to whitelist or blacklist filters.
* Added belt immunity equipment.
* Added upgrade planner.
* Added steam networking support for steam users.
* Added RGB support for Logitech hardware.
* Robots can blow up cliffs.
* Wave defense scenario has been reworked to support multiple rounds and a procedurally generated map.
* Added a research queue that becomes available after the player has finished the game by launching a rocket with satellite.
=== Minor Features ===
* Warning icon for automated trains that are out of fuel.
* Added 250 and 1000 hours precision intervals into statistics.
* Using deconstruction planner is incorporated in the latency hiding.
* Changed personal roboports so they won't send construction robots if you're driving in a vehicle that they can't keep up with or if in a train in automatic mode.
* Added an option to ignore mouse events when using accessibility zoom feature on macOS.
* Added support to change multiplayer config settings runtime.
* Added support to edit the whitelist, banlist, and admin list when hosting a multiplayer game.
* Added the Admin GUI (openable through /admin in the console) to manage multiplayer players.
* Landfill can be built by robots and be included in blueprints.
* Blueprint items taken from blueprint library will not move to player inventory when Q is pressed, but can be moved to any slot explicitly. (Same as with clipboard items)
* When selecting any item to the cursor from some of the player inventories. As long as the item is being held, hand icon is shown on the slot it was taken from. The hand prevents any other item to be inserted into the slot as long as the player cursor isn't cleared.
* When holding radar in cursor, area covered by existing radars is also highlighted on minimap.
* Configurable (in gui), the count of rolling stocks shown in the train visualization.
* Added two levels of shallow water tiles (only placed by map editor, not generated). Enemies and vehicles can travel over shallow water.
=== Graphics ===

** chests
** electric poles and substation
** map edge transitions
** rocket silo
** transport belts, underground belts, splitters and transport belt circuit connector
** trees
** turrets (gun, flamethrower and laser)
** walls and gates
* laser turrets, personal laser defense and distractor robots now use new laser beams.
* Highlighting inserters that would interact with selected/previewed entity.
* Showing shield bars above health bar for relevant entities.
* Single vertical pipe is shorter.
=== Gui ===
* New final versions of several important GUI screens (Quick bar, Train Schedule, Load/Save Game, Settings, Map Generator, Research, Mods)
** Other screens than the mentioned ones (more than 100) have inconsistencies and will be updated in future minor updates.
* The quickbar is no longer an inventory, instead it can only hold shortcuts it items in inventory or blueprint library.
** The quickbar now has 10 pages of shortcuts.
** Player inventory increased by 20 slots to compensate. Toolbelt research further increases the player inventory.
* In the map, station and tag selection is now visualized by the standard Factorio selection box graphics instead of highlighting.
* Added interface option: When selecting a buildable item from the quickbar or when using the pipette tool, if you have no items of that type, a ghost will be placed in the cursor instead.
* When something is not buildable (manual or blueprint building), the reason of why it isn't buildable is shown as flying text over the cursor when the build is attempted.
* Only compatible results of a furnace are manually placeable in the result slot. (Mainly to avoid confusion of new players)
=== Optimisations ===
* Modernized and optimized rendering backend. The game now uses DirectX 11 or OpenGL 3.3 Core and requires DirectX 10 class graphics card.
* DirectX backend doesn't keep backup of all sprites in RAM anymore.
* Added high quality texture compression to reduce amount of video memory consumed by the game and increase overall rendering performance.
* Added texture streaming so that adding more sprites does not necessarily increase GPU requirements.
* Improved game startup performance when using a large amount of technologies with deep dependency trees (it's now 67,000 times faster).
* Optimized rendering of logistic overlay when zoomed in to map. ([https://forums.factorio.com/60659 more])
* Optimized rendering of turret ranges when zoomed in to map. ([https://forums.factorio.com/58991 more])
=== Changes ===

** Biter bases will increase in size, frequency and number of worms depending on the distance from player spawn.
** Worm size increases depending on the distance from player spawn.
** Small biter bases are now closer to the player spawn.
** At large distances from player spawn, biter base frequency is lower than before but biter bases are larger.
** Other small tweaks.
* Terrain generation changed significantly:
** Water is generated as large lakes instead of swamps.
** Tile generation improved. Tile placement respects biomes better.
** More predictable cliff placement.
** Better controls in the map generator GUI for water, tiles and cliffs.

* When the "Made in" row is shown in the recipe tooltip, player icon is added to the list when it is craftable by player.
* Increased ghost time to live of ghosts from 1 hour to 1 week.
* Since the catalysts have been tweaked, the kovarex enrichment process can now be used together with productivity module.
* Tile construction jobs are being handled by robots separately from entity building jobs, to prevent entity ghosts not being built due to large number of tile ghosts.
* Switched key bindings from key codes to scan codes. This solves an issue with bad default key bindings on layouts that are not similar to US QWERTY (ie. AZERTY).
* Armor no longer uses durability and all armor now has a stack size of 1.
* Manually putting modules into machines that are requesting modules from the logistic network will reduce the modules requested.
* Increased maximum train stop length from 50 to 100 characters so it can fit at least 3 tags in most cases.
* Items consumed by hand crafting are counted in item production statistics.
* Added --disable-migration-window command-line option to disable the "migrated content" gui.

* Removed Wood from the game (And raw wood renamed to Wood).
* Added rotation smoothing to biters.
* Chests and wooden power poles are no longer usable as fuel.
* Burner efficiency is set to 100% for all entities and fuel value is halved to simplify calculations. This should not change game balance.
* Removed the hardness/mining power mechanics, we just have a mining speed and mining time now.
* Manual mining speed times of various entities will differ a bit, but probably not in a noticeable way.
* Stone and other ore mining speed has been unified to be 1 (apart uranium ore, which is 2 and shown as 200% mining time)
* Mining drill speed is now shown in the form of <x>/s (0.25/s for burner mining drill, 0.5/s for electric mining drill), the relative mining speeds of the mining machines have been decreased a little so the numbers are rounded nicely (0.28 -> 0.25 and 0.525 -> 0.5).
* Renamed the whitelist and banlist to server-whitelist and server-banlist.
* Added server-adminlist that's used to determine which people are admins when hosting any multiplayer game. This is synced both ways when hosting any game.
* Removed "admins" from the multiplayer server-settings file - they're now handled through server-adminlist.
* "Z" (drop item) will drop single items into what ever entity is selected instead of only dropping on the ground.
* Stickers can by applied onto cars and tanks now.
* Changed the chat gray-out mechanism. It always greyed-out after 5 seconds to 70% alpha, and then stayed depending on the setting. Now it stays 100% and only greys out away in the last 2 seconds.
* Placing entities or paths removes tree stumps and biter corpses.
* Removed New Hope campaign.

== 0.17.0 ==
Date: 26. 02. 2019
=== Major Features ===
* New quickbar (more in Gui section)
* Added shortcut bar that allows quick access to certain game features, such as toggling alt mode, creating blueprints, or turning off personal roboport
* New gui style with final version of some parts of the GUI (More in Gui section)
* Added clipboard functionality. (Control + C, Control + X, Control + V activate appropriate tools) Shift + mouse wheel allows to cycle the clipboard history.
* Added undo functionality (Control + Z). Supports manual entity building and by blueprints and manual mining and usage of deconstruction planner.
* Reworked the Map Editor so it's now part of the standard game and can be toggled at will using the '/editor' command.
* Support for mod synchronisation when joining multiplayer game. Works as long as the used mods are on the mod portal.
* Fight changes. Enemy projectiles are dodgeable and slowdown/damage the target over time. They also leave splashes on ground that have the same effect.
* Rich text tags. These tags can be used almost anywhere: Chat, station names, save names, custom ui and probably a few places we didn't think of.
** They allow changing color, font, images and location/blueprint/armor/station/locomotive linking through chat. (More in features)
* Fluid mixing prevention. Actions that fail as they would lead to fluid mixing (like building a pipe, changing recipe, rotating etc.) produce an error message as flying text.
* Replaced First steps campaign with Introduction campaign, available from the Start campaign menu.
=== Features ===
* Trains can be blueprinted and deconstructed.
* Trains can be given temporary stations (by Control+clicking the map). Temporary station is automatically removed once the train departures from it.
* Train stops without conditions work as waypoints. (the train doesn't stop at those)
* Added Passenger present and Passenger not present wait condition to the train conditions.
* If building of entity/blueprint fails, the reason of it is pinged as flying text.
* Map pings. Ctrl+Alt+click on the map to show a ping in all players maps at that location.
* Basic image tags format is [img=<image path>] where image path can use item, entity, technology, recipe, item-group, fluid tile, virtual signal achievement or utility icon.
** For example [img=item/iron-plate] or [img=item.iron-plate]. The "." instead of "/" usage is to make it usable in save names.
** Additionally, items/entities/technologies/recipe/item-group/fluid/tile/virtual signal or achievement can be linked directly by [item=iron-plate], [recipe=iron-plate], or [entity=small-biter] to provide tooltip for the appropriate object.
* Blueprint/special item tags.
** Shift clicking the icon in chat will create an item and place it in the cursor.
** Format is [special-item=blueprint string], eg: [special-item=0eNp1jtEKwjAMRX9l5rnCxkShvyIi3YxboU1Lm4lj9N9N54sv5iFwL/eeZIPBLRiTJQa9gR0DZdDXDbKdyLjq8RoRNFhGDwrI+Ko4GcoxJD4O6BiKAksPfIPuyk0BElu2+CXtYr3T4gdMEvjHUBBDllqgelVQrYJVdqnE/br+eVaBM1ITb0bnQvNMwTc8YzPOhiZ0YTpI5oUp78BL33YnmbY/l/IBb4pSQQ==].
** These tags also work with deconstruction and upgrade planners.
* Map ping tags: Created by shift-clicking the ground/map when the chat is open. Format is [gps=x,y], eg [gps=10,30] will show a map ping in all players maps at location 10,30.
** Clicking the icon in chat will open the map on the specified location.
* Font tags: Format is [font=debug-mono]mono text[/font].
* Color tags: Format is [color=1,0,0]red text[/font]
* Fast replacing pipes by pipes to ground similar to underground belts.
* When multiple versions of the same mod are installed you can select which version you want to use.
* The sync mods with save/multiplayer game feature can now sync mod startup settings as well as mods.
* Added support to import and export permissions.
* Closing opened items (blueprint books/armor) now remembers what GUI you previously had open.
* Filter inserters can be set to whitelist or blacklist filters.
* Added belt immunity equipment.
* Added upgrade planner.
* Added steam networking support for steam users.
* Added RGB support for Logitech hardware.
* Robots can blow up cliffs.
* Wave defense scenario has been reworked to support multiple rounds and a procedurally generated map.
* Added a research queue that becomes available after the player has finished the game by launching a rocket with satellite.
=== Minor Features ===
* Warning icon for automated trains that are out of fuel.
* Added 250 and 1000 hours precision intervals into statistics.
* Using deconstruction planner is incorporated in the latency hiding.
* Changed personal roboports so they won't send construction robots if you're driving in a vehicle that they can't keep up with or if in a train in automatic mode.
* Added an option to ignore mouse events when using accessibility zoom feature on macOS.
* Added support to change multiplayer config settings runtime.
* Added support to edit the whitelist, banlist, and admin list when hosting a multiplayer game.
* Added the Admin GUI (openable through /admin in the console) to manage multiplayer players.
* Landfill can be built by robots and be included in blueprints.
* Blueprint items taken from blueprint library will not move to player inventory when Q is pressed, but can be moved to any slot explicitly. (Same as with clipboard items)
* When selecting any item to the cursor from some of the player inventories. As long as the item is being held, hand icon is shown on the slot it was taken from. The hand prevents any other item to be inserted into the slot as long as the player cursor isn't cleared.
* When holding radar in cursor, area covered by existing radars is also highlighted on minimap.
* Configurable (in gui), the count of rolling stocks shown in the train visualization.
* Added two levels of shallow water tiles (only placed by map editor, not generated). Enemies and vehicles can travel over shallow water.
=== Graphics ===
* New graphics for:
** accumulator
** biters, spitters, worms, spawners
** chests
** electric poles and substation
** map edge transitions
** rocket silo
** transport belts, underground belts, splitters and transport belt circuit connector
** trees
** turrets (gun, flamethrower and laser)
** walls and gates
* laser turrets, personal laser defense and distractor robots now use new laser beams.
* Highlighting inserters that would interact with selected/previewed entity.
* Showing shield bars above health bar for relevant entities.
* Single vertical pipe is shorter.
=== Gui ===
* New final versions of several important GUI screens (Quick bar, Train Schedule, Load/Save Game, Settings, Map Generator, Research, Mods)
** Other screens than the mentioned ones (more than 100) have inconsistencies and will be updated in future minor updates.
* The quickbar is no longer an inventory, instead it can only hold shortcuts it items in inventory or blueprint library.
** The quickbar now has 10 pages of shortcuts.
** Player inventory increased by 20 slots to compensate. Toolbelt research further increases the player inventory.
* In the map, station and tag selection is now visualized by the standard Factorio selection box graphics instead of highlighting.
* Added interface option: When selecting a buildable item from the quickbar or when using the pipette tool, if you have no items of that type, a ghost will be placed in the cursor instead.
* When something is not buildable (manual or blueprint building), the reason of why it isn't buildable is shown as flying text over the cursor when the build is attempted.
* Only compatible results of a furnace are manually placeable in the result slot. (Mainly to avoid confusion of new players)
=== Optimisations ===
* Modernized and optimized rendering backend. The game now uses DirectX 11 or OpenGL 3.3 Core and requires DirectX 10 class graphics card.
* DirectX backend doesn't keep backup of all sprites in RAM anymore.
* Added high quality texture compression to reduce amount of video memory consumed by the game and increase overall rendering performance.
* Added texture streaming so that adding more sprites does not necessarily increase GPU requirements.
* Improved game startup performance when using a large amount of technologies with deep dependency trees (it's now 67,000 times faster).
* Optimized rendering of logistic overlay when zoomed in to map. ([https://forums.factorio.com/60659 more])
* Optimized rendering of turret ranges when zoomed in to map. ([https://forums.factorio.com/58991 more])
=== Changes ===
* Resource generation changed significantly:
** The starting area contains only iron, copper, coal and stone, in very predictable amounts. Uranium and oil are excluded from the starting area.
** Resource generation settings now have a much more dramatic effect. Increased the number of steps for each setting.
** Ore patches are slightly less frequent but richer.
** There will be a more balanced amount of resources within a large enough region.
** Many other small tweaks.
* Biter generation changed significantly:
** Biter richness slider removed, biter placement is only configured by size and frequency settings.
** Biter generation settings now have a much more dramatic effect. Increased the number of steps for each setting.
** Biter bases will increase in size, frequency and number of worms depending on the distance from player spawn.
** Worm size increases depending on the distance from player spawn.
** Small biter bases are now closer to the player spawn.
** At large distances from player spawn, biter base frequency is lower than before but biter bases are larger.
** Other small tweaks.
* Terrain generation changed significantly:
** Water is generated as large lakes instead of swamps.
** Tile generation improved. Tile placement respects biomes better.
** More predictable cliff placement.
** Better controls in the map generator GUI for water, tiles and cliffs.
* New map terrain type selectable: Island. Launch the rocket with only a limited amount of resources available on the map.
* Default resolution of the game is now 1920x1080.
* Increased player reach from 6 to 10.
* Inserters are putting science packs to the lab even when there is no research in progress or when the research doesn't need that particular pack.
* Default_request_amount removed in all places where it was used. Default logistic request is 1 stack, unless changed by the setting "Default request is 1".
* All personal equipment stack sizes changed to 20.
* Placing a tile will now clear any tile ghosts at that position. ([https://forums.factorio.com/59721 more])
* It is allowed to use unicode characters in save names.
* Recipes that have more ingredients than the assembling machine allows are now shown as red instead of not present when selecting the recipe.
* When the "Made in" row is shown in the recipe tooltip, player icon is added to the list when it is craftable by player.
* Increased ghost time to live of ghosts from 1 hour to 1 week.
* Since the catalysts have been tweaked, the kovarex enrichment process can now be used together with productivity module.
* Tile construction jobs are being handled by robots separately from entity building jobs, to prevent entity ghosts not being built due to large number of tile ghosts.
* Switched key bindings from key codes to scan codes. This solves an issue with bad default key bindings on layouts that are not similar to US QWERTY (ie. AZERTY).
* Armor no longer uses durability and all armor now has a stack size of 1.
* Manually putting modules into machines that are requesting modules from the logistic network will reduce the modules requested.
* Increased maximum train stop length from 50 to 100 characters so it can fit at least 3 tags in most cases.
* Items consumed by hand crafting are counted in item production statistics.
* Added --disable-migration-window command-line option to disable the "migrated content" gui.

* Removed Wood from the game (And raw wood renamed to Wood).
* Added rotation smoothing to biters.
* Chests and wooden power poles are no longer usable as fuel.
* Burner efficiency is set to 100% for all entities and fuel value is halved to simplify calculations. This should not change game balance.
* Removed the hardness/mining power mechanics, we just have a mining speed and mining time now.
* Manual mining speed times of various entities will differ a bit, but probably not in a noticeable way.
* Stone and other ore mining speed has been unified to be 1 (apart uranium ore, which is 2 and shown as 200% mining time)
* Mining drill speed is now shown in the form of <x>/s (0.25/s for burner mining drill, 0.5/s for electric mining drill), the relative mining speeds of the mining machines have been decreased a little so the numbers are rounded nicely (0.28 -> 0.25 and 0.525 -> 0.5).
* Renamed the whitelist and banlist to server-whitelist and server-banlist.
* Added server-adminlist that's used to determine which people are admins when hosting any multiplayer game. This is synced both ways when hosting any game.
* Removed "admins" from the multiplayer server-settings file - they're now handled through server-adminlist.
* "Z" (drop item) will drop single items into what ever entity is selected instead of only dropping on the ground.
* Stickers can by applied onto cars and tanks now.
* Changed the chat gray-out mechanism. It always greyed-out after 5 seconds to 70% alpha, and then stayed depending on the setting. Now it stays 100% and only greys out away in the last 2 seconds.
* Placing entities or paths removes tree stumps and biter corpses.
* Removed New Hope campaign.
