  • When using /swap-players undo queues are now also swapped.
  • Improve performance of querying if an entity is registered for deconstruction from O(N) to O(1).
  • Adjusted default music volume.


  • Fixed that if biters took damage from a forest fire, they would path toward the player who started it, no matter the distance. more
  • Fixed 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.
  • Fixed that LuaGameScript::ban_player would incorrectly use reason as a player name when given player was never in game. more
  • Fixed that the saving progress bar and other popups were placed behind the transparent pause overlay. more
  • Fixed a scenario could be created with temporary-state trains which were not properly deleted. more
  • Fixed a crash when using --map-settings while loading a multiplayer map. more
  • Fixed that trying to manually mine a resource that needs a mining fluid would sometimes produce sound of mining. more
  • Fixed script rendered arcs could be considered invisible when they were visible. more
  • Fixed that LuaEntity::belt_neighbours would return LuaEntity based on EntityGhost's inner entity, not the EntityGhost itself. more
  • Fixed fish preventing tiles building with check_collision_with_entities enabled.
  • Fixed that trains would not account for the train stop snap distance when already at the train stop with the back of a train. more
  • Fixed the intro music volume being set incorrectly.
  • Fixed that --start-server-load-latest when given an empty saves folder wouldn't work correctly. more
  • Fixed missing efficiency tooltip and incorrect fuel consumption tooltip value in generator equipment with burner energy source.
  • Fixed ghost electric poles connecting to ghost electric poles of other forces. Neutral force is exempt from this change. more

  • 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.


  • Added LuaEntityPrototype::trigger_collision_mask read.
  • Added LuaEntity::is_military_target read. This deprecates LuaEntity::is_entity_with_force.
