* Fix reversing a train inside a depot disrupting the PBS reservation of another train heading into the depot.
* Fix ships being drawn with the wrong image direction after rotating in place in some circumstances.
* Fix ships with images which depend on speed not being redrawn when the speed has changed.
* Fix signals on dual railtype tiles using wrong per-railtype custom signals.
* Fix conditional order loops on leaving a depot when a timetabled wait time is set.
* Signals on bridges/tunnels:
* Fix tunnel exit signal not being set to red when train exited.
* Fix signals on bridge middle parts not using per-railtype custom signals.
* The signal spacing distance is now fixed at signalling time, changing the company spacing setting now only affects newly signalled bridges/tunnels, not existing ones.
* The signal spacing distance is now automatically adjusted to fit the tunnel/bridge length. This is to avoid the last middle signal being too close to the exit signal.
* Routing restrictions:
* Add slot action: try to acquire (only on reserve).
* Fix last station visited not being set when the reservation ends at the target station, this could cause long-reserve conditionals to use the wrong last station visited value.
* Fix reverse behind signal pathfinding when there is no dead-end beyond the signal.
* The reverse behind signal pathfinder now takes into account the train length to avoid reversing sidings which are too short.
* NewGRF:
* Allow using NewGRF switches (Action 2/3) for general rail signal sprites, in the same way as per-railtype signal sprites.
* Enable recolouring of signal graphics.
* Add support for multi-aspect signal graphics (requires realistic braking).
* Realistic braking:
* Adjust braking constants to slightly increase train braking forces.
* Block signals into blocks with junctions now default to red with realistic braking.
* Template-based train replacement:
* Show refitted capacity when adding template vehicles with cargo filter.
* Show buy cost and running cost in template windows.
* Allow cloning trains directly from the template train list.
* Add new signal type: no-entry signal. (This is not shown by default).
* Add sort by number of vehicles calling to station list window.
* Add improved breakdowns speed reductions for ships.
* Train speed adaption: adjust look-ahead distances at lower speeds.
* Make remove and routing restriction buttons in the signal build window mutually exclusive.
* Add hotkey support to the signal build window.
* Add spectate menu item to company toolbar menu.
* Send back a message for rcon and settings_access failures.
* Show linear scaling value in settings window for cargo scaling settings.
* Add support for retrieving JGRPP-only content from the Bananas content service.
* Add Korean translations by TELK.
### v0.42.3 (2021-08-04)
* Fix multiplayer server crash when client joined during a threaded save or autosave.
* Fix station ratings tooltip in right click mode.
