    • Adjusted default music volume.

    Bugfixes

    • Addressed that if biters took damage from a forest fire, they would path toward the player who started it, no matter the distance.
    • Addressed that replacing a tile between a colliding hidden tile (with check_collision_with_entities set to true) and an entity would not yield an item.

    • Addressed a scenario could be created with temporary-state trains which were not properly deleted.
    • Addressed a crash when using –map-settings while loading a multiplayer map.
    • Addressed that trying to manually mine a resource that needs a mining fluid would sometimes produce sound of mining.
    • Addressed script rendered arcs could be considered invisible when they were visible.
    • Addressed that LuaEntity::belt_neighbours would return LuaEntity based on EntityGhost’s inner entity, not the EntityGhost itself.
    • Addressed fish preventing tiles building with check_collision_with_entities enabled.
    • Addressed that trains would not account for the train stop snap distance when already at the train stop with the back of a train.
    • Addressed the intro music volume being set incorrectly.
    • Addressed that –start-server-load-latest when given an empty saves folder wouldn’t work correctly.
    • Addressed missing efficiency tooltip and incorrect fuel consumption tooltip value in generator equipment with burner energy source.

    Modding

    • Added EntityPrototype::protected_from_tile_building, true by default. If set to false – entity won’t block tile mining/building (with `TilePrototype::check_collision_with_entities` enabled).
    • Added LandMinePrototype::trigger_collision_mask.
    • Added EntityWithOwnerPrototype.
    • Added EntityWithOwnerPrototype::is_military_target and allow_run_time_change_of_is_military_target.
    • SimpleEntityWithForce now inherits from SimpleEntityWithOwner.
    • SpiderEnginePrototype::military_target is no longer used. If anything is provided it will make related SpiderVehiclePrototype to become a military target instead.

    Scripting

    • Added LuaEntityPrototype::trigger_collision_mask read.
    • Added LuaEntity::is_military_target read. This deprecates LuaEntity::is_entity_with_force.
    • Added LuaEntityPrototype::is_entity_with_owner, is_military_target and allow_run_time_change_of_is_military_target read.
    • Added LuaEntity::get_spider_legs().
    • Added LuaEntity::neighbours read for cliffs.
