Changes:
-Mod checksums are calculated when the game starts and are compared with other peers when joining a multiplayer game. This is to ensure everyone has exactly the same mod in order to prevent desyncs caused by local changes made to mod files.
Bufixes are:
-Fixed strange outer corner for rendering terrains with the same layer.
-Fixed Factorio timing out of a multiplayer game when closed by pressing the X button.
-Building things after quitting a multiplayer game is no longer possible and no longer crashes the game.
-Fixed memory leak with special signals in the circuit network.
-Fixed crash when killing the player in on_built_entity.
-Fixed crash when making blueprints of ghosts with some now-invalid circuit connections to other ghosts.
-Fixed target shooting is not updating properly when the target's force became friendly
-Fixed the documentation of CircuitCondition
-Fixed that the ignore_planner field of Command would expect an integer instead of a boolean.
-The Starting value of the progress bar is now properly set based on the input.
-Fixed crash when destroying the entity with empty corpse of the string.
-Fixed mining drills getting stuck when the built-in pointing at rails and then rotated.
-Fixed remote. call () within the same mod passing invalid data.
-Fixed the typo in the error "mulitplayer. cant-load-downloaded-map", the cause of the error wasn't displayed because of it.
-Fixed that the server could get desynced and in a state where he has no one to download from.
-Fixed that the train was showing the tooltip the current station as the next one when in the station.
-Fixed crash when a Lua function was used as a value in a table in data.raw.

so it is clear, it limits only the input, but not output.
-Fixed that cancelling a recipe in the crafting of the queue would reset the timer crafting unnecessarily.
-Fixed crash when a force other than player, enemy or neutral was used in autoplace specification.
