- Fix: TTO savegames with any aircraft not in an hangar caused crashes during load (r22915)
- Fix: Windows 2000 and XP without service pack 3 must use the win9x binary/installer; the newer MSVC compiler of the compile farm does not support those versions of Windows anymore [FS#4749] (r22909)
- Fix: Some corrupted savegames could crash OpenTTD instead of showing the 'savegame corrupted' message [FS#4717] (r22737, r22736)
- Fix: Triggering NOT_REACHED when playing with a NewGRF that supplies genders/cases for a language that was not installed [FS#4718] (r22735)

- Fix: [NewGRF] The override managers were not reset in some cases like creating a new scenario [FS#4691] (r22693)
- Fix: [NewGRF] Aircrafts defined with IDs above the default aircrafts always defaulted to passenger cargo (r22690)
- Fix: [NewGRF] Implement variables 25 and 7F for railtypes (r22633)
- Fix: [NewGRF] Additional text in fund industry window is NewGRF supplied and thus should have a default colour (r22631)
- Fix: Also initialise _old_vds with newgame settings; TTD savegames do not contain these settings [FS#4622] (r22626)
- Fix: Do not zero the orders of disaster vehicles when converting savegames [FS#4642] (r22625)
- Fix: Callback result for airport layout name was incorrectly used (r22496)

- Fix: Engine IDs for coal and mail wagons were swapped in the TTO savegame conversion [FS#4622] (r22487)
- Fix: The caption of centered windows could be moved out of the main window and thus become inaccessible when resizing the main window (r22485, r22484)
- Fix: Only try to insert implicit orders for ground vehicles. Aircraft may reach unscheduled terminals when skipping orders etc [FS#4624] (r22492)
- Change: Automatic orders are better called implicit orders as no real order influencing path finding is added (r22474, r22473)
- Fix: Crash when clicking a removed company in the vehicle list dropdowns [FS#4592] (r22373)
- Fix: Make sure saving has completely and utterly finished before starting a new one. Otherwise you could start a save, which would be marked as done by the previous save stopping and then yet another save could be started... and that could create a deadlock [FS#4596] (r22371)
- Fix: When inserting automatic orders, do not create consecutive duplicate orders (r22333, r22332, r22331, r22330, r22329, r22328, r22327)

- Fix: Windows video driver crashed when it could not go to full screen at the resolution of the configuration file when starting OpenTTD [FS#4521] (r22149)

- Fix: Some valid keycodes were ignored along with the invalid ones (r22142)
- Fix: When commands need to invalidate windows, process these events asynchronously before the next redraw. Calling window code directly from command scope uses wrong _current_company and might issue nested DoCommands() which interfer with the running command [FS#4523] (r22141, r22140, r22135, r22134)
- Fix: [NewGRF] Skipping only the invalid part of an action14 failed, the rest of the action was skipped instead (r22138)
- Fix: When a NOT_REACHED in saveload can be reached due to an invalid savegame, use SlErrorCorrupt instead. In other words, do not crash but show an error message (r22122)
- Fix: In case of high frame_freq one could get commands executed after a new network game was started (r22121)

-Fix: Various other issues with automatic orders, e.g. vehicles getting stuck with "no orders" when there are automatic orders at the end of the order list.
