Software-update: OpenTTD 0.5.3

Het spel 'Open Transport Tycoon Deluxe' borduurt verder op het idee van Transport Tycoon Deluxe, een succesvol computerspel uit 1995 waarin de speler een transportbedrijf bestuurt en het moet opnemen tegen rivaliserende bedrijven in een strijd om het grootste transportimperium te worden. OpenTTD wordt onder de gpl-licentie uitgebracht en is voorzien van nieuwe en verbeterde features, waaronder grotere levels en de mogelijkheid om online tegen andere spelers te spelen. Hoewel OpenTTD opensource is, heeft het spel wel enkele bestanden nodig van een originele kopie van Transport Tycoon Deluxe. Die bestanden bevatten auteursrechtelijk materiaal en kunnen daardoor niet zomaar gebruikt worden in een opensourceprogramma. De ontwikkelaars hebben versie 0.5.3 uitgebracht met de volgende aankondiging en lijst van aanpassingen:

Today we have released 0.5.3 which contains lots of small bugfixes and a few major bugs that could lead to remotely triggered crashes of servers and/or clients. We therefor urge you to update to 0.5.3.

New Features:

• Feature: Make the client list window (for network games) stickyable
• Feature: console command to get the current game date

Bugfixes:

• Fix: Possible NULL pointer dereference that could be triggered remotely
• Fix: Removing CMD_AUTO from some commands could remotely trigger an assertion
• Fix: Underflow that caused overflows in the performance rating
• Fix: [Windows] MIDI does not stop when closing openttd
• Fix: Do not unconditionally assume that a tile has a depot
• Fix: Give a more correct error when building some things on tile 0
• Fix: Do not display income/expenses when they do not belong to a "valid" tile, like the money cheat and giving money
• Fix: One could not give money when (s)he had too much money
• Fix: Disallow buying/selling shares in your own company or a bankrupt company
• Fix: Crash when quiting the game in one of the end score windows
• Fix: Spectators are not allowed to issue commands
• Fix: Make the AI not crash when it has ships as the AI does not support them
• Fix: Trains would not get flooded when they are at the lower part of a tile that would become a coast tile after flooding
• Fix: Removing road with the road removal tool would also work with a negative bank account, making the bank account even more negative than it was
• Fix: Some isocodes were wrong, resulting in some NewGRF not working properly for the affected languages
• Fix: [Windows] Do not try to minimise or restore the window when closing OpenTTD
• Fix: Trains going over bridges would get the "going down hill" accelerate bonus, which causes trains to go faster on bridges than they would be going on level land
• Fix: Trains being split into two pieces when loading an old savegame
• Fix: [OS/2] Fix chdir problem with open/save dialog
• Fix: One could not remove locks that were build in a (very) old version of OpenTTD
• Fix: One cannot navigate using arrow keys in the game name text box
• Fix: Ship's maximum speed wrongly shown
• Fix: [OSX] Of the resolution is changed to something that is too high for the monitor, then it is reduced to fit the monitor size, solving several crashes and graphical glitches
• Fix: NPF was leaking memory each time it got initialized, except for the first time
• Fix: [YAPF] 'target_seen' flag that is set prematurely in some cases (1 tile long cached segment followed by target station) which caused asserts to trigger
• Fix: Visual glitches when a window is resized in the WE_CREATE callback
• Fix: [Windows] _wnd.has_focus was not properly set after using ALT-TAB
• Fix: Waypoints could be renamed when you are not the owner
• Fix: Smooth economy did not close primary industries and it allowed increasing of production of industries that should not have rising productions
• Fix: Acceleration for trains on slopes is not calculated properly
• Fix: The 'old' pathfinders (OPF and NPF) for road vehicles could not find a path when in a tunnel
• Fix: Only add the autoreplace menu when autoreplace actually knows about the group
• Fix: Signal state sometimes not properly set when the signal "pathfinder" reached the end of a line
• Fix: News messages were shown over the endgame/highscore windows
• Fix: Rail could be destroyed when building tunnels
• Fix: Flush the output of the dedicated server console
• Fix: The "pause" key did not work in the scenario editor
• Fix: Age non-front engines too (so when you move engines around in the depot they do not get age 0 when they are much older
• Fix: Do not make everyone spectator if 1 joining client failed to create new company
• Fix: Remove invalid characters (for the file system) from savegame names
• Fix: Some old savegames could have the wrong bits unset
• Fix: Do not look in every direction for tunnels when building one, one direction is enough
• Fix: [Windows] Do not mess desktop when using ALT-TAB
• Fix: Take the age of the front vehicle for station rating
• Fix: Terraforming wipes out canals. Now you always have to remove the canal before terraforming, instead of "just" removing the canal
• Fix: Only 2 trains could crash at one time as collision checking stopped on the first hit. This could technically cause desyncs in network games as the collision hash order is not guaranteed
• Fix: Land under foundations was terraform when it shouldn't be terraformed
• Fix: Do not make a 270 degree turn on the international airport when a 90 degree turn is enough
• Fix: Crash when trying to get the aircraft movement state of an aircraft going to a just deleted airport
• Fix: Airports did not flood when there are aircraft on the airport
• Fix: Some vehicles were not drawn when having a high resolution and a high zoom-out level
• Fix: Vehicles disappear when crossing certain tiles
• Fix: Train disconnects in some old TTD savegames
• Fix: OpenTTD assumes that the resolution is at least 1 by 1, so force the resolution to be always at least 1 by 1
• Fix: When you got a sufficiently small resolution, there is a possibility for a division by zero when a sound is played
• Fix: When removing a dock, a ship will always try to reach the old location of the dock even when it cannot anymore because it the old location of the dock is now land instead of water
• Fix: SetCurrentGrfLangID returned the wrong language ids for most languages
• Fix: Some NewGRFs use the same (unused in the "current" climate) sprite IDs. Normally this gives some artefacts, but when one NewGRF expects it to be a sprite and another NewGRF overwrites it with a non-sprite nasty things happen (drawing a non-sprite crashes OTTD)
• Fix: Multiple subsequent "give money" actions could result in duplicate messages that money has been transfered when it only happened once, or tell you paid money when you did not
• Fix: "Deactivate Electrified Railways" did not work
• Fix: Memory leaks in the networking code
• Fix: Coverage area highlight was still show when it was turned off for docks
• Fix: Do not use override engine type for articulated wagon parts
• Fix: Sprite resulting from '?' substitution was reloaded into the cache entry for SPR_IMG_QUERY instead of the original sprite cache entry. This resulted in unaccounted missing sprite cache memory, and was exacerbated because the original missing sprite was not cached, so it did it again and again and again. Slowdowns and boom
• Fix: One could build on (some) slopes when building on slopes was disabled
• Fix: When deleting the first engine of a train with multiple engines, only reopen the train window if the player had the original train window open. This fixes 'random' windows opening for multiple players of the same company
• Fix: When selling trains, if there were no wagons between multiheaded engines the rear part could be checked despite having already been deleted
