The on_init and on_configuration_changed still retain the access to the game API.
• on_configuration_changed is fired when the map version changes, a mod version changes, a mod is added, or a mod is removed and passes "data": Pushes old_version="x.x.x", new_version="x.x.x" when loading map versions other than the current version When a mod version is changed it appears as a table of mod Changes {["Mod name"] = {old_version="x.x.x", new_version="x.x.x"}, ...} When a mod is added it appears as: ["Mod name"] = {old_version=nil, new_version="x.x.x"} When a mod is removed it appears as: ["Mod name"] = {old_version="x.x.x", new_version=nil}

• Added personal roboport as modular armor equipment. Once it is active, it uses the materials and robots in the players inventory. It supports all the tasks construction robots can do like building blueprints, repairing structures, deconstruction etc.
• Added logistic trash fields to the character GUI. They supply items into the logistic system in the same way active provider chests do.
• Added combinators (Arithmetic Combinator, Decider Combinator and Constant combinator). These allow more advanced manipulation with the circuit network logic (more)
• The Lamp, Storage Tank, Small Pump and Offshore Pump can be connected to the circuit network.
• Multiplayer latency hiding (gives impression that some common tasks are performed immediately) Applies to character movement, mining buildings, building, fast replacing, opening guis, etc.
• Stone brick can be used to build stone path. (30% walking speed increase).
• Concrete can be created. The concrete can be used to build concrete floors (40% walking speed increase).
• Terrain modifies vehicle friction force (sand: 1.8, grass: 1.6, dirt: 1.4, stone path: 1.1, concrete: 0.8).
• Trees degenerate slowly when there high pollution levels.
• Lab research is now continuous. Science packs have progress bars of usage. This means that 20 labs doing research with 10 units will still be faster than 10 labs and the science packs aren't wasted.
• Assembling machine input slot can contain more than the usual stack size when the recipe requirement demands it (3 X recipe demand). Example: The rocket silo requires 1000 steel, while the stack size is 100, but the input stack can hold enough.
• Added / updated sounds for biters, spitters, worm, spawner, flamethrower, tank, lasers, etc.
• New ambient soundtrack added. Added mechanism that prevents playing track that was played recently. The ambient player alternates between neutral wind/environment sounds and soundtrack songs.
• Mousing over a train will show you its current path and blocks it can't enter.
• Locomotives now show the contents of attached cargo wagons in their tooltip.
• Trees regenerate health slowly.
• Added support for transferring contents/settings when fast-replacing all entity types.
• Added modules to the alt-view for entities that support modules.
• Factorio can run as a dedicated server without Graphics (more).
• Basic PvP: New forces can now be created and merged back together; a cease-fire can be agreed upon between forces
• IPv6 support for multiplayer.
• DNS names can be used when connecting to multiplayer game.
• Enabled mining trees/ghosts while holding blueprints to be built.
• Added explosive cannon shells.
• Building blueprints over existing ghosts restores the ghost time to live to full.

Changes

• Disabled loading of saves before 0.9.0 version (You can use 0.9.8 to load older saves and re-save them).
• Removed rocket defense entity.
• Items on transport belts don't go off the belt at the end, so the transport belt has to go directly in front of the required inserter.
• Reduced number of rendered Roboport connections.
• The trade in the marketplace only happens if the player can accept the trade items.
• Inserters can now extract from Roboports and Beacons.
• Inserters now take items from right behind them, not from the center of the pickup target entity.
• Copy entity settings mechanism now remembers only the last entity copied from. Also mechanism allows copy/paste across different entities of the same type (i.e. assembling machine 1 -> assembling machine 2) and from assembling machines to requester chests (sets filters to 2 x requirements of the assembling machine).
• Trees have generally smaller bounding boxes, so it is easier to walk through forest.
• Power armor modules generate and consume 100 times more power in order to be able to charge construction robots.
• The construction robots don't build gate in the gap between the rolling stock vehicles. They wait for the train to get away.
• Player's logistic filters are now remembered after respawn in multiplayer
• All turrets are now 2x2 (incorrectly stated as 4x4); laser turrets are 4x more expensive and powerful, gun turrets are 2x more expensive
• Roboport tooltip now shows correct numbers of construction and logistic robots separately.
• When a train loses a path and cannot find a new one, it stops immediately. This prevents it from riding into parts of the rail network, from where it can't find a path.
• Improvements to circuit network wire connection. You can connect multiple wires of the same color to the same entity.
• The autosave dialog no longer cancels an active blueprint or deconstruction planner selection if the mouse button is still held after the autosave finishes
• Number of autosave slots is now configurable through config.ini (no GUI).

Optimizations

• Overall optimization of train + belt heavy factories is roughly 66% compared to 0.11, this means that the game runs 3 times faster.
• Optimised the transport belt movement.
• Optimised the rotated bounding box collisions checks (trains).
• Optimised the smoke update.
• Optimised the solar panel, all the solar panel input is merged, so the count doesn't matter.
• Optimised the accumulators by merging then into groups, where typical factory has 1 group per network.
• Optimised the land mine activation mechanism.
• Smaller multiplayer heartbeat packet size.
• Optimised adding/removing of roboport, robots keep their tasks if they can.
• Path finder will terminate when search is too long. This avoids save explosions (see more).
• Optimised rendering for large logistic networks.
• Fixed that the Graphics were saved twice in the RAM memory.

Graphics

• New Graphics of the combat robots.
• New Graphics of the laser/gun turrets, their color is now player/force dependent.
• New Graphics of muzzle flash for player, car, tank and turrets.
• New tree Graphics. Trees have 4 levels of leaves and the leafs are color-able.
• Trees emit leaves (based on the tree color) when being mined and destroyed.
• Trees emit branches when mined or destroyed.
• Storage tank has a small window showing the liquid inside.
• Combat robots attack beam (more)
• New GUI icons: Weapons, ammo, status icons such as out-of-ammo or out-of-electricity

• Fixed that control-clicking entire inventory into a machine installed modules.
• Fixed another instance of the "Trying to make chunk at unreasonable position" bug (more).
• Requester chests no longer request more than they can store. E.g. if a requester chest only has one free slot and the requester slider is set to request 20000 iron ore, the chest will only request one stack from the network (more)
• Console no longer loses focus after an autosave (more)
• Fixed wrong highlight when crafting ammo in vehicles (more)
