Modding

• Added UnitPrototype::light.
• Removed the "particle" prototype type.
• Added the "optimized-particle" prototype type.
• Added the "burner-generator" prototype type.
• Removed GeneratorPrototype::burner.
• Added the "pass_through_mouse" option to speech bubble styles. This lets mouse interactions fall through to interact with the world behind.
• Added optional "radius_color" property to capsule prototype.
• Removed EntityPrototype::emissions_per_tick, it is replaced by emissions_per_second.
• Removed EnergySourcePrototype::emissions_per_second_per_watt and emissions, they are replaced by emissions_per_minute.
• Removed TilePrototype::ageing, it is replaced by pollution_absorption_per_second.
• Removed ItemPrototype::stackable, primary_place_result_item and can_be_mod_opened, they were replaced by ItemPrototypeFlags "not-stackable", "primary-place-result" and "mod-openable".
• Added "probability" to trigger items and trigger effect items.
• Added "script" trigger effect item. It will call the "on_script_trigger_effect" when triggered.
• Added AttackParameters::rotate_penalty and AttackParameters::health_penalty.
• Added generic support for rendering radius visualisations on entities through radius_visualisation_specification.
• Changed construction robots and logistic robots sprites to be optional.
• Changed the loader prototype type so it has a fixed belt_distance of 0.5.
• Added the prototype type "loader-1x1" that has a fixed belt_distance of 0.
• Changed render layer of belt structures (underground belt, splitter, circuit connector) to object layer. They now have special sorting logic, so they are not rendered over player or cars.
• Horizontal directions of splitter sprites were separated to two sprites (for purposes of the special sorting logic).
• Added AttackParameters::ammo_categories.
• Added optional artillery projectile property "rotatable".
• Scenarios can now contain a description.json file. In the file "order" determines the sorting in the New Game gui; "multiplayer-compatible" determines weather the scenario is shown for multiplayer games.
• Added "multiplayer-compatible" to description.json file of campaigns also.

Scripting

• Added on_unit_group_finished_gathering and on_build_base_arrived events.
• Added LuaRendering::bring_to_front().
• Changed LuaGameScript::particle_prototypes to reference the optimized-particle type.
• Added LuaGuiElement::scroll_to_item() function.
• Renamed LuaInventory::hasbar(), getbar() and setbar() to supports_bar(), get_bar() and set_bar().
• Added LuaEquipmentPrototype::attack_parameters read.
• Added on_script_trigger_effect event.
• Set lower limit of zoom parameter of LuaGameScript::take_screenshot to be 0.0315 (1 pixel per tile) instead of allowing any value greater than 0.
• Added LuaPlayer::get_infinity_inventory_filter(), set_infinity_inventory_filter() functions.
• Added LuaPlayer::remove_unfiltered_items, infinity_inventory_filters read/write.
• Added LuaSurface::get_entities_with_force().
• Added optional "dealer" parameter to LuaEntity::damage().
• Added "force" filters to the on_built_entity and on_robot_built_entity event filters.
• LuaSurface::min_brightness doesn't have any effect on rendering as brightness of night depends only on color LUT of night.
