Features:
Added --no-auto-pause: When running as a server, --no-auto-pause will prevent stopping the game when no players are connected.
Optimisations:
Optimised the particle performance. Helps during heavy fights.
Changes:
Showing the log file location when the game crashes, so it is eaiser to find when reporting the bug.
The "graphics.force-opengl" option default value is true when AMD graphics card is present.
Bugfixes:
Fixed that multiple electric networks connected to a solar panel could be exploited to generate more energy. (viewtopic.php?t=16778) The energy of the solar panel is now fractioned between all the networks it is connected to.
Fixed character entities disconnected from players not working correctly when in vehicles. (viewtopic.php?t=16812)

Removed one possible logical deadlock in the tutorial. (viewtopic.php?t=16980)
Fixed that remove_item didn't remove from player ammo, gun, tool and armor slots. (viewtopic.php?t=16960)
Scripting:
Changed LuaSurface::set_multi_command signature. Now the function takes a table with following keys: command(required), unit_count(required), force(optional), unit_search_distance(optional) This solves issue with not finding any enemies to attack: viewtopic.php?f=7&t=16541
Removed game.on_save function. There should be no need for it and it was causing too many problems.
Lua on_load function is not called when saving the game anymore. It is called only on actual load now.
Lua API calls on_load, on_init, on_configuration_changed, on_event and generate_event_name have been moved to a new namespace called script (so from now use script.on_load(...)). This will break many mods! The callback registered in on_load function doesn't have access to the game API. This is to avoid common desyncs. 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}
Changed LuaGameScript::makefile to LuaGameScript::write_file and added an optional third parameter bool to append.
Modding:
Replaced entity type "rail" with types "straight-rail" and "curved-rail". Property "bending_type" is optional for rail entities, but is still mandatory for rail remnants.

Entries in the mod list GUI are highlighted in red only when enabled and invalid at the same time.
Added natural case-insensitive string ordering for the mod list GUI.
There is now only one spawn position per each force and per each surface. This means that only one spawn position can be defined in the map editor as it currently supports only the default surface and the "player" force.
Added force-opengl value in config (under graphics). When set to true, it forces to use opengl on windows instead of D3D.
Map scrolling speed now changes with zoom level.
Bugfixes:
Inserters take items from correct line when the input transport belt is rotated
Solved the "A blocking operation was interrupted by a call to WSACancelBlockingCall" error (hopefully as we can't reproduce it).

Fixed desync issue related to inventory sorting and blueprints.
Fixed that amount_max in recipe specification actually worked as amount_max -1.
Fixed that mining tiles did actually create mining particles+sound on the lastly mined entity.

Added LuaEntity::revive() - usable on ghost entities to revive them back to normal.
Fixed that that the resource amount while creating the entity accepted non-positive values.
Added LuaForce::set_spawn_position(surface, position) and LuaForce::get_spawn_position(surface)
Fixed that the event queue was never cleared when scripting error occurs while processing it. This lead to processing the same event every update once the game was stopped when error happened.

This will reset everyone's multisampling setting to 0.
Construction robots take things primary from the main inventory, then quickbar.
Reverted the order of inserter slot selection.
Added Alt-mode (showing entity info) to the latency hiding.
Trains now try to recalculate their path, when waiting over 5 seconds on a signal (only if needed).
The recalculation is forced when waiting over 30 seconds.

Fixed ghost inserter arrows being displayed incorrectly
Zooming works comfortably also when mapped on buttons, as holding the button continuously zooms in/out instead of doing just one small zoom step.
Proper direction filtering (8 way versus 4 way) when building ghosts from script. The direction is now dependent on the ghost inner entity limitation.
Fixed that the new lamp entity was off-center.
Fixed behemoth biter resistance specification.

New in Factorio Demo 0.12.0 Experimental (Jul 21, 2015)

Features:
The game is now finished by launching the rocket with satellite.
Added chain signals, they can be used to make more complicated junctions and stations without deadlocks.
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 (https://www.factorio.com/blog/post/fff-88)
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 (http://www.factorioforums.com/wiki/inde ... ess_server).
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 4x4; laser turrets are 4x more expensive and powerful, gun turrets are 2x more expensive
Roboport tooltip now shows correct numbers of contruction 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).
Optimisations:
Overall optimisation 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 viewtopic.php?f=7&t=12580).
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 leafes and the leafs are colorable.
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 (https://www.factorio.com/blog/post/fff-84)

Fixed that control-clicking entire inventory into a machine installed modules.
Fixed another instance of the "Trying to make chunk at unreasonable position" bug (viewtopic.php?f=7&t=13399).
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 (viewtopic.php?f=30&t=4604)
Console no longer loses focus after an autosave (viewtopic.php?f=30&t=10025)
Fixed wrong highlight when crafting ammo in vehicles (viewtopic.php?f=30&t=9620)

Added several new options to LuaEntityPrototype: mineable_properties, items_to_place_this, collision_box, selection_box, order, group, subgroup, healing_per_tick, emissions_per_tick, corpses, selectable_in_game, weight, resistances, fast_replaceable_group, loot, repair_speed_modifier
LuaItemPrototype::group now returns the new LuaGroup object.
Added LuaEntity::is_crafting() - returns true/false if the assembling machine or furnace is currently crafting a recipe.
Added LuaEntity::crafting_progress/bonus_progress - a percent of 1: the current crafting progress or bonus progress.
Added the ability to compare LuaObjects using "==" as in: "if game.player == game.players[1]" for all LuaObjects.
Removed all LuaObject::equals(): the == operator can be used in its place.
Added new blend modes for sprites using "blend_mode" property. Possible values: "normal", "additive", "multiplicative".

Changed LuaEntity::neighbours:
For electric poles: the wire connections: {copper={}, red={}, green={}}
For transport-belt-to-ground: the input/output entity it's connected to (or none)
For entities with fluid - the entities the fluid connections connect to indexed by the fluid connection

New in Factorio Demo 0.12.0 Demo (Jul 21, 2015)

Features:
The game is now finished by launching the rocket with satellite.
Added chain signals, they can be used to make more complicated junctions and stations without deadlocks.
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 (https://www.factorio.com/blog/post/fff-88)
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 (http://www.factorioforums.com/wiki/inde ... ess_server).
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 4x4; laser turrets are 4x more expensive and powerful, gun turrets are 2x more expensive
Roboport tooltip now shows correct numbers of contruction 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).
Optimisations:
Overall optimisation 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 viewtopic.php?f=7&t=12580).
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 leafes and the leafs are colorable.
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 (https://www.factorio.com/blog/post/fff-84)
New GUI icons: Weapons, ammo, status icons such as out-of-ammo or out-of-electricity
Bugfixes:
Fixed wrong item count in the logistic system when handling partially-filled magazines, repair packs or other items with durability
Fixed the choppy (not smooth) movement when using the exoskeleton equipment.
item-description localization now displays correctly when previewing recipes.
entity-description localization now displays on entities.
Proper blueprint centering. It is based on the included entities rather then the selection rectangle when the blueprint is created.
Very big entities no longer disappear at the edge of the screen
When putting things on ground, the first item was never put exactly under the cursor even when the place was empty.
Fixed that it wasn't possible to swap stacks of the same items with different health.
Fixed strange behavior of tank/car entering sound.
Fixed LuaFluidBox crashing the game when attempting to read fluid from an entity that previously had fluidboxes.
Car / Tank ammo inventory is refilled from the trunk / player inventory when exhausted.
Fixed writing invalid LuaEntity::selected_gun_index crashing the game.
Fixed the power armor battery level indicator getting drawn on top of everything else (viewtopic.php?f=48&t=8206).
Fixed that following robots created through trigger crashed the game.
Fixed the train pathfinding issue when the train crashes to something while stopping for signal or station in front of a junction.
Fixed that crashing to something while in manual mode in train could switch it to automatic mode.
Fixed crashing when setting modded GUI styles in Multiplayer.
Fixed crash when trying to read LuaPlayer::opened on a dead player.
Fixed crash when canceling deconstruction of a logistic container that was marked for deconstruction after the logistic network it was in lost power and then regained power (viewtopic.php?f=7&t=10143).
Fixed LuaSurface::can_place_entity returning true when checking item-on-ground against item-on-ground (viewtopic.php?f=7&t=9247).
Turrets can now be modded to use shotgun (and other not guided) ammo.
Fixed research window appearing behind the selection/minimap pane when shown from research completion (viewtopic.php?f=7&t=13235).
Fix inability to bind some OEM keys on Windows. Added the ability to bind more keys including multimedia keys. (viewtopic.php?t=10027)
Fixed marking a ton of entities for deconstruction outside the construction range of roboports slowing down normal deconstruction rates.
Fixed crash when removing electric poles from electric networks or circuit networks with large amounts of poles (viewtopic.php?f=7&t=13368).
Fixed video-memory-usage option on Windows. It is possible to run Factorio on configurations with low VRAM (less then 512MB). Other platforms don't have this issue.
Fixed that control-clicking entire inventory into a machine installed modules.
Fixed another instance of the "Trying to make chunk at unreasonable position" bug (viewtopic.php?f=7&t=13399).
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 (viewtopic.php?f=30&t=4604)
Console no longer loses focus after an autosave (viewtopic.php?f=30&t=10025)
Fixed wrong highlight when crafting ammo in vehicles (viewtopic.php?f=30&t=9620)
