OpenTTD Changelog

What's new in OpenTTD 1.9.3

Oct 7, 2019

This release especially focuses on two issues hitting macOS users: Many have had really bad performance, with framerates below 10 on the title screen. The cause was identified to be colourspace conversions happening (big thanks to SoothedTau in issue #7644) and found a fix. There is a risk this causes incorrect colours, hopefully that’s an acceptable trade-off. Additionally, some misconfigured multiplayer servers have been sending out server names with invalid UTF-8 text, revealing a bug in text handling on macOS, causing crashes. This has also been fixed.
Apart from those two bugs, there are also some other improvements: UI scaling fixes, text fixes, file browser sorting, and it’s become a little easier to send vehicles to oil rigs and other water industries. For those playing city builder scenarios in particular, a certain playstyle was causing crashes when building road stops over one-way roads, this is also fixed.

[NewGRF] Make the properties for always/never refittable cargo types not behave incremental, but reset them on reassignment (r23960)

32bpp animated blitter was optimised a bit too far regarding not needing to update the colour mapping when (re)initialising the palette [FS#5056] (r23927)
[NoGo] Some news messages would cause an assertion to be triggered due to a missing proper location for the viewport of the news message, so only allow building when valid data for the viewport is provided or no viewport is used [FS#5054] (r23924)
Consider only the middle tile of a lock for lock-infrastructure costs. The other two tiles may be owned by other companies. Also do not count the middle tile of a lock as canal, independent of whether it is build on ground or river slope (r23920)
[NewGRF] When determining the first refittable cargotype according to CTT order, do not rely on the GRF assigning the refit_mask property. Also check for GRFs setting the default_cargo or refittable-cargo-classes or -types properties (r23916)
[NewGRF] Do not test validity of cargobits using a mask of cargoslots (r23914)

New features:
[NewGRF] Give NewGRF defined level crossings and rail depots access to the townzone (r23866)
[NewGRF] New algorithm (activated via an engine flag) to determine the capacity of vehicles.

Railtype overlays were drawn 'only transparent' on invisible bridges (r23864)
Inserting conditional orders for ships checked the wrong orders wrt. maximum distance (r23859)
Out of bounds read for slowdown parameter caused desync when railtype >= 4, vehicles were fast, and the original acceleration model was used [FS#5007] (r23855)
Infrastructure cache could get out of sync when overbuilding a drive through road stop (r23851)
When the network is lagging, you try to copy a vehicle's order but accidentally create a station order and then copy the vehicle's order (before the first command is executed) one could trigger an assertion from the pool [FS#5008] (r23849)
When removing road or tram from a tram+road stop, the owner of the road stop's cache was updated instead of the owner of the removed infrastructure (r23847)

If autorefit fails, count the vehicle capacity nevertheless, if it is already carrying the right thing (r23745)
[NewGRF] Check the version of the right GRF [FS#4923] (r23744)
[NewGRF] Call CB 15E for all vehicles before actually executing any refit [FS#4906] (r23743)
Cheating to different climates messes things even more up than changing NewGRFs in-game so it was removed [FS#4939] (r23733)

Infrastructure count of canals/locks/ship depots was not updated properly when a company went into bankruptcy or was taken over [FS#4921] (r23686)
When fitting another engine the cargo capacity of wagons could become lower, causing them to contain more than they should. This caused the cargo transfer from the replaced parts to put even more stuff in the already full wagon. Prevent this from happening by reducing the amount of cargo in the vehicle to the capacity when moving vehicles/wagons around, or when autoreplacing [FS#4912] (r23683)

Use the same forest-check for the vegetation-map colour as for nearby station names [FS#4810] (r23049)
Check that the selected font size is valid the font face in use and choose the nearest size to that selected if not. Font metrics should then just work (r23038)

When the last used server is deleted from the list also clear the last used server if it is the same [FS#4791] (r23011)
[NewGRF] Make sure temporary storage is cleared before test and exec runs for DoCommands so NewGRF callbacks cannot change the result between the runs (r22996)
[NewGRF] Tile was cleared before the object-placement callback was run, resulting in possible differences in test and exec run [FS#4775] (r22994)

[NewGRF] Properties for feature 0x05 were not zeroed for each NewGRF, thus waterfeatures could glitch when the properties were set by a previous NewGRF and the NewGRF assumed the properties to be unmodified (r22918)
Old TTO/TTD savegames could get non-stop via orders upon savegame loading, even when those orders did not exist back then. This 'conversion' feature is something for TTDPatch and old OpenTTD savegames [FS#4716] (r22914)
The icon would (almost) never be shown for SDL builds [FS#4617] (r22910)
The name of the heightmap glitches in the 'play heightmap' window (r22902)

[NewGRF] Only allow access (via hotkey and menu) to the bounding box visualisation when NewGRF developer tools are enabled (r22675)
Fixed:

Keep the previous owner of the upper and lower lock parts if they are built on existing water (r22638)
[NewGRF] Airports should not expose the tile specific random bits of the north tile. Only airport tiles should access those (r22636)

When closing down companies their shares in other companies must be sold even if share trading is disabled at that point of time (r22622)

Enforce refit orders to be 'always go to depot' orders; service-only and stop-in-depot orders make no sense with refitting [FS#4651] (r22620)
Consider the size of the vehicle sprite for the lineheight in the company GUI. This also makes the widget containing the sprite not skip drawing it, if the bounds of the widget are outside of the drawing area though the sprite actually needs drawing [FS#4662] (r22619)
When changing difficulty settings over the network, do not just reopen the difficulty window if any game options window is opened; instead invalidate them properly [FS#4653] (r22618, r22617)

Engine IDs for coal and mail wagons were swapped in the TTO savegame conversion [FS#4622] (r22487)
The caption of centered windows could be moved out of the main window and thus become inaccessible when resizing the main window (r22485, r22484)
No client error packet was sent to the admin bots [FS#4585] (r22384)

Some valid keycodes were ignored along with the invalid ones (r22142)
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)

Build-station-window showed wrong selection when reopening [FS#4530] (r22128)
Canals would get drawn as land in the smallmap when using the owner window (r22127)
The animation-ness of two goldmine tiles were swapped, causing the wheeltower to not work properly, and the bottom corner to show the wrong sprite [FS#4528] (r22125)
CommandQueue::Pop() did not update 'last'; popping the last item caused the queue to disconnect unless there was only one item [FS#4522] (r22123)
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)
In case of high frame_freq one could get commands executed after a new network game was started (r22121)
[NoAI] Prevent AIs from getting consistently over their allowed amount of operations by subtracting the amount they went over 'budget' from the budget for the next 'tick' (r22120)
The refit window was not correctly updated after selecting with Ctrl+Click [FS#4525] (r22118)

New features:
[NewGRF] Test all possible industry layouts during construction and prospecting [FS#4131] (r22012, r22010)
Wheel scrolling in the console (r21982)
Console command to reset the engine pool. It removes the traces of engines which are no longer associated to a NewGRF, and can be used to e.g. 'fix' scenarios which were screwed up by the author. You can only use it when there are no vehicles in the game though (r21975)
Add a setting to enable/disable funding local road reconstruction (r21974)
Introduce 'minimal' number of industries as a replacment for the old 'none' setting in the new game window (r21969)
Changes:
When loading old savegames with long trains set the maximum train length to the length of the longest train (r22061)
Always report mammoth trains are disabled to NewGRFs, and allow the maximum train length to be modified in multiplayer as well [FS#4471] (r22004)
Fixed:
Remove invalid keycodes when reading hotkeys.cfg [FS#4510] (r22094)
The server list did not get sorted with one item in it, so the 'position in the list' variable was never updated causing problems when using the keyboard shortcuts for scrolling [FS#4514] (r22093)
When deleting towns, only relocate objects during DC_EXEC (r22087)
[Windows] If fullscreen fails with current resolution, use desktop resolution [FS#4489] (r22081)
The owner view of the smallmap was not updated after a company colour change (r22079)
Maximum train length interfered with wagon replacement when wagon removal was turned on [FS#4499] (r22078)
NewGRFs with invalid multi-tile houses could cause a valid 1x1 house following it to be seen as multi-tile, causing crashes [FS#4501] (r22075)
Immediately update the train weight when you change the multiplier for train cargo weight (r22073)
Some hotkey names in hotkey.cfg for the scenario editor toolbar were completely bogus (r22071)
Crashes when disconnecting after requesting the map [FS#4503] (r22070)
Delete all savegame packets, not just the first one (r22069)
Return 'connection lost' instead of 'okay' when SendPackets closed the connection, so we do not try to do anything else with the closed socket (r22068)
Do not hold a mutex when sending packets and thus possibly closing the connection as that wants to acquire the mutex again (r22067)
Verify we can allocate an Order, OrderList, CargoPacket, CargoPayment, and others before we actually try to do so (all corner cases) [FS#4468] (r22066, r22057, r22047, r22042, r22040, r22033, r22031, r22026, r22025, r22024, r22023, r22022)
Crash when disconnecting and reconnecting while the server is still saving the savegame [FS#4497] (r22064)
Memory leak when saving with LZMA or zlib fails mid-way (r22062)
Make the send chat message window follow the position of the status bar (r22059)
Metric and imperial HP are not the same. As imperial HP are used internally, set a conversion rate for metric HP [FS#4408] (r22056)
[Squirrel] Some invalid squirrel code caused the squirrel compiler to crash [FS#4490] (r22055)
The land area information window was not updated after a language change (r22053)
Roads under road stops would get a wrong owner after overbuilding (r22051)
In ancient savegames, e.g. TTO savegames, non primary vehicles (wagons and such) could have unitnumbers or even orders. However, these orders would not be updated when a station is removed. As such some savegames have wagons with current orders to invalid stations which triggers trouble in the load conversion. So, trash any orders/unitnumbers a non-primary vehicle has [FS#4496] (r22050)
[NewGRF] Company 0 does not always exist, so put temporary vehicles in a valid company (r22048)
Make sure order indices stay in range when copying, sharing, unsharing or deleting all orders [FS#4487] (r22046)
Update the consist cache when a part of a train is flipped in the depot [FS#4493] (r22044)
Invalidate the right windows when a part of a train is flipped in the depot (r22043)
Tab completion in chat did not cycle through all possible options (r22038)
Crash when watching the vehicle view of a vehicle that has multiple sequential nearest depot orders (or consists of a single nearest depot order) when there is no depot with index 0 [FS#4488] (r22034)
The server list got not resorted/redrawn after NewGRFs were downloaded [FS#4482] (r22029)
When paused and having the allowed actions while paused setting on 'no actions' cheating money would fail [FS#4479] (r22016)
Only show one AI per unique ID instead of all versions in the output of 'openttd -h' (r22007)
Smoke/sparks of trains would be shown under bridges, or rather through bridges [FS#4480] (r22006)
When the difference between force and resistance is smaller than the mass(*4) there would be no acceleration anymore, even when at higher (or lower) speed the force and resistance balance out better [FS#4473] (r21997)
[YAPF] Under some circumstances vehicles could be lost [FS#4472] (r21996)
[NewGRF] Make computations of closest-land/water-distances handle waterish tiles more correctly (r21994)
When building a lock on dry land costs for clearing water were deducted rather than for building canals (r21993)
AIs trying to change the AIOF_GOTO_NEAREST_DEPOT flag for existing orders triggered an assert. Explicitly forbid this as precondition for SetOrderFlags [FS#4467] (r21992)
The share/copy-orders-cursor was not updated to refer to the new vehicle when it got autoreplaced/-renewed [FS#4466] (r21991)
Vehicle status bar glitches on speed changes (r21989)
Scrolling of the console in pages used wrong line height and scrolled too much (r21979)

Show the length of vehicles in tiles, instead of half tiles in the depot (r21960)
Replace longbridges settings with custom maximum bridge and tunnel length setting (r21959)
Randomize the vehicle a small UFO targets, do not use the one with lowest index (r21949)
Fixed:
Do not count the number of vehicles but the length of vehicles to (configurably) limit train length [FS#4461] (r21960)
[NewGRF] Reset the carry flag every 4 bytes in Action 6 when adding more than one variable (r21951)
Road vehicle was moved under the bridge when it was destroyed by an UFO while on a bridge (r21948)
Crash when converting a savegame with vehicles crashed in a tunnel entry, or with vehicles reversing there (r21947)
Funny behaviour when a road vehicle reverses while overtaking, so abort the overtake attempt when reversing the road vehicle [FS#4447] (r21946)
Not all vehicles should be tested to be inside a tunnel upon savegame load [FS#4460] (r21940)

Allow to overbuild road stops which are built over trams (r21935)
Automatic orders behave now stable wrt. service orders and are not added or removed depending on the need of servicing [FS#4440] (r21933)
The town window would not be invalidated in the scenario editor if the ground changed and thus the required cargos for town growth [FS#4554] (r21929)
Converting an expensive rail type to a cheap one could give more money than removing and rebuilding cost (r21919)
Languages improperly sorted in the 'start server' window [FS#4443] (r21918)
the minimum speed needed for (realistic) acceleration to work properly can sometimes be more than the (temporary) maximum speed causing Clamp to 'fail'. Make sure that the minimum speed always overrules the maximum speed [FS#4442] (r21916)
Include the capacity of non-refittable vehicles in the refitted-capacity, if their cargo matches (r21904)
Do not count articulated parts when passing the number of vehicles to refit to the command. That may exceed 8 bits (r21902)
[NoAI] Hide automatic orders from AIs as they have no way of dealing with them (r21900)
Do not show a vehicle selection in the RefitWindow for refit orders. You cannot select anything anyway (r21899)
Using a pointer-iterator and adding things (thus reallocating) to the iterated array caused OpenTTD to crash on invalid pointers [FS#4438] (r21898)
Only some scenarios from the main scenario folder and no heightmaps could be started in the 'start server' window [FS#4421] (r21892)
Crash when scrolling outside of the main window (with some video backends) [FS#4434] (r21889)
[NewGRF] String codes 0x80 and 0x81 were broken since the typechecking of string parameters [FS#4422] (r21885)
When a train after reversing ended at the last bit of a bridge ramp and directed outside the bridge, it could still have track set to TRACK_BIT_WORMHOLE (r21880)
When a single-vehicle train was reversed while on a slope, its GOINGUP/DOWN were not swapped (r21874)
Removed:
Settings for vehicle speed in the vehicle view, long date in status bar, drawing of bridge pillars, support for depot orders, time tabling and joining of stations upon building (r21958, r21957, r21956, r21955, r21954)
The non-uniform stations setting; it has been broken for over a year, and thus not used [FS#4456] (r21953)

New in OpenTTD 1.1.0 Beta 4 (Jan 24, 2011)

New features:
[NewGRF] Rail type property to influence sorting of rail types in the drop down list [FS#4394] (r21866)
[Network] Console command to change the password of other companies for servers [FS#4368] (r21855)
[NewGRF] Introduction dates/required types for rail types; e.g. introduce a particular rail type in 1960 (or when a vehicle using it is introduced), but also allow limiting its introduction to only happen when the required railtypes are available [FS#4393] (r21842)
Limit vehicle lateness to the length of a full timetable cycle, e.g. when a cycle takes 50 days and the vehicle is 65 days later reduce the lateness to 15 days (r21832)

Changes:
Allow LMB scrolling with the mouse outside of the extra viewport instead of canceling scrolling when going slightly over the edge (r21838)

Keep aqueducts and road/tram tunnels and bridges after removing a company (r21780)
Fixed:
Distant-join station would build at the wrong location when having persistent building turned on and selecting a 'second' location for the station tile [FS#4430] (r21864)
Slowing down of trains was done by reducing the speed by 10%, but also when you are just 1% too fast, so limit the slowdown till the new maximum speed [FS#4423] (r21847)
Left-mouse-button dragging would switch over to other viewports instead of staying locked to the viewport you started on [FS#4419] (r21837)
When a train was reversed while inside a tunnel/bridge, it would not have (re)set the GOINGUP/DOWN bits after leaving the tunnel/bridge (r21836)
Desync debug savegames might not be actually saved in case threading is enabled, which is enabled by default [FS#4427] (r21833)
Service orders for trains/aircraft would (sometimes) not get a time when autofilling [FS#4414] (r21831)
Crash with the small map window on big endian platforms [FS#4417] (r21830)
The expectations from the 'always build infrastructure' setting name/description did not match the behaviour [FS#4007] (r21826)
Allow dragging of combo signals (again) [FS#4378] (r21816)
[YAPF] Apply a pathfinder penalty for back of one-way path signals so those arenot preferred over other possibilities [FS#3908] (r21815)

Loading a TTO savegame failed after loading a TTDP savegame (r21799, r21798)
The size (in characters) of the string inputs was too small for loading some TTD savegames (r21797)
Drive through road stop state was not properly converted from TTDPatch savegames [FS#4398] (r21796)
Broken usage of GetTileOwner() caused wrong conversion of old savegames (r21793)
Terraforming limit was off-by-one when terraforming a single tile height [FS#4407] (r21791)
TTDPatch savegames can have train waypoints encoded as buoys [FS#4398] (r21790)
When the font misses the fallback character '?', use the sprite font's '?' instead [FS#4405] (r21789)
Crash due to invalid rail station width and height data stored in TTDPatch savegames [FS#4398] (r21786)
Crash when converting savegame with custom waypoint name (r21784)

Allow changing the AI configuration in the scenario editor / in game [FS#4362] (r21696)
Change:
Tune 'realistic' acceleration even more to make more trains reach their top speed, and make it behave more like TTDPatch (r21712)
Display the minimum height of the tile in the LandInfo window instead of the height of the northern corner. So it is more useful for NewGRF and AI developers, and maybe more transparent for players (r21711)
Fixed:
The diagonal iterator would iterate twice over some tiles [FS#4395] (r21747)
[NewGRF] Canal variable 83 accessed water random bits also for non-water tiles (e.g. watery industries or objects) (r21746)
[NewGRF] Canal variable 80 shall return consistent heights within a lock (r21745)
Allow Ctrl+Clicking automatic orders for scrolling to their destination (r21744)

[NewGRF] Report TTDPatch flag 4A (newobjects) as set (r21708)
The old ship pathfinder is too stupid to provide 'lost' notices; it would even get lost while following its own path [FS#4370] (r21706)
Do not perform any more checks after the connection is closed [FS#4374] (r21704)
Changing AI settings ingame was impossible when the difficulty level was other than custom (r21694)

New in OpenTTD 1.1.0 Beta 2 (Jan 2, 2011)

New features:
Command logging using the admin interface (r21668)
Concept of automatic station orders; add stub orders for intermediate stations and remove them when not visiting them anymore. This allows you to see what trains visit a station without actually having to order a vehicle to stop at all stations (r21642)
Added:
[NoAI] AIEventTownFounded (r21664)
[NoAI] AIRail::GetName() to get the name of a railtype (r21663)
[NoAI] AITown::IsCity() so AIs can find out which towns grow faster than others (r21654)
Changed:
Do not show price to build a bridge in the scenario editor as they are free to build there [FS#4358] (r21673)
Do not highlight tile when selecting a vehicle to clone or an order to skip to (r21616)
Fixed:
Estonia introduced the Euro in 2011 (r21670)
Autofill timetable had side effects in test mode, possibly causing desyncs in MP [FS#4354] (r21660)
Cargo payment graph was not properly invalidated when payment rate changed [FS#4351] (r21658)
Use a bool instead of uint8 to store a bool and use the dedicated accessor function when reading boolean settings [FS#4345] (r21656)
Infinite loop in the road pathfinder due to bouncing around in an 'one way' trap; two one ways pointing towards eachother making it impossible to leave [FS#4338] (r21651)
Make '[centre|main] view' consistent, and make '[main|global] view' consistent [FS#4339] (r21650)
Newly created skip-to order was created at wrong place (r21633)
Ships with the old pathfinder would easily show up as lost, even when it would eventually find a path. Now also the distance from the 'end' of the pathfinding run to the destination is compared to the current distance to the destination; if the distance to the destination at the end of the pathfinder run is less than the current distance from the destination the ship will not be marked as lost. This means that the ships with the old pathfinder will less likely get marked as lost, but due to the design of the old ship pathfinder there 'lostness' is merely a best guess. When you still get a lost message you need to build buoys to guide the ship pathfinder [FS#4325] (r21631)
Version detection of subversion branches and tags got broken (r21630)
Crash under certain circumstances when using autorail [FS#4327] (r21619)

Scroll to the inserted order [FS#4215] (r21457)
Building while paused always works in the scenario editor [FS#1521] (r21430)
Perform the compression of savegames to send to the client asynchronously.

[NewGRF] Add CB36 support for road vehicle properties 0x13 (Power), 0x14 (Weight) and 0x18 (Tractive effort) (r21058)
XZ/LZMA2 savegame support. New default reduces savegame size by 10 to 30% with slightly more CPU usage. With maximum settings it reduces savegame size by 20 to 30%, but that takes 7 to 14 times longer. Map saving + downloading takes, on average, 5% less (r21044)
Chat directly to the server or a bot/admin/IRC channel monitoring the server (r21000)

More user-friendly gui to change NewGRF parameters (r20258)
[NewGRF] Add support for static NewGRF information, i.e. Action 14 (r20250)
Display suppliers and customers of an industry or cargo (r20206)
Allow horizontal resizing for all vehicle lists [FS#3955] (r20174)

Hide all other industries when Ctrl+clicking an industry type in smallmap legend (r19770)
[NewGRF] Access to random bits of houses and industries from construction callbacks 17, 28 and 2F. That is: The random bits the house/industry will start with, if construction succeeds [FS#3477] (r19744)
A simple sprite alignment helper. It does not store the new offsets anywhere so as soon as the sprite is reloaded the offsets are gone (use a bigger sprite cache if this happens). Also anything that reloads NewGRFs (new games, loading games or (re)applying NewGRFs) clears the sprite cache and as such resets the offsets (r19723)
New base costs for building/clearing canals, building/clearing aqueducts and building/clearing locks (r19720)
Ctrl+click on a vehicle to start/stop it (r19714)
NewGRF debugging/inspecting of (primarily) enabled callbacks and values of variables (r19709)

Support for MSVC 2010 (r20032)
[NoAI] AIIndustry::GetIndustryID(TileIndex) (r19773)
Changed:
Make it possible to start actions that require selecting stuff (landscaping, vehicle cloning, etc) in the viewport while paused. As side-effect you will get an error message explaining the command cannot be executed because the game is paused instead of seemingly nothing happening when you click. Additional side effect of this is that you can make use of the measurement tooltip while paused [FS#4292] (r21480)
Make building aqueducts behave more like building tunnels. They cannot be built on flat (or foundationed) tiles, so there is at most one destination tile like there is only one for tunnels [FS#4153] (r21471)

Read some metadata from (official) source tarballs so you will more likely get the right version/revision out-of-the-box (r21351)
Be more explicit that the game state can get broken by changing NewGRFs (r21335)
Use the last red instead of last red exit penalty for making sure other waypoint entries are evaluated as well when they are occupied, e.g. when there are no signals before the waypoint but a train just beyond the waypoint is stopped (like for stations) (r21271)
Do not receive money for removing the rail of non-rail rail station tiles, i.e. rail station tiles for which the NewGRF has prevented trains to be routed through (r21266)
Show a different 'lag' message when a client is lagging because of connection trouble or lagging because the client is just slow (r21254)
Mention the OpenTTD version on the console/logs when starting an OpenTTD dedicated server like we mention it in the title bar for the GUI version (r21253)
Filter stations by cargo they have a rating for instead of having cargo waiting [FS#4206] (r21144)
Limit the number of exceptions in the refittable cargo list to 7 (r21083)
Reduce the chances to accidentally break savegames with NewGRFs by limiting loading of savegames that miss NewGRFs or change NewGRF settings in-game [FS#3012] (r21116)
Tuned realistic acceleration to be a bit more realistic in order to make acceleration 'slower', which highlights the differences between vehicle types more (r21106)
Do not make client reconnect waiting time depend on the company; in coop games that does not spread clients at all, and most companies have a low number causing it not to be spread out either. Use the ClientID instead. (r21008)
Add installing options or rather options to not install certain documentation, in a similar way to GRFCodec/catcodec (r20999)

[NewGRF] Adapt vehicle var FE bit 6 to new railtypes (r20175)
[NewGRF] Call callbacks 14A, 14B and 14C after all industry variables have been assigned, so more variables are valid during the callbacks (r19907)
[NoAI] Remove HasNext() from all lists/iterators and add IsEnd() instead (r19294)
Add the default installation directory of lzo/zlib for Mac OS X/MinGW to the paths where (the headers of) those libraries are searched [FS#3638] (r19285)
Fixed:
Crash due to cargo payments belonging to a non-existing company [FS#4324] (r21605)
Company league table used stats from two quarters ago instead of last quarter [FS#4323] (r21601)
The default visual effect only depends on properties of the Engine (wagon or not, tractiontype, ...), not whether it is used as articulated part, front engine or whatever in a specific consist [FS#4275] (r21598)
[OSX] A double mouse cursor was shown under certain circumstances [FS#2585] (r21578)
Show 'plant trees' button lowered on the terraform toolbar, like how other buttons are lowered when you selected a 'build' action [FS#4315] (r21539)
2CC recolour sprites were the same for DOS and WIN palette, thus 'dark green', 'brown', 'grey' and 'white' were wrong for DOS [FS#4312] (r21535)
Do not apply the last signal red pathfinder penalty when the signal is a path signal [FS#4302] (r21524)

[NewGRF] Ensure the parameter for house variable 60 is the id of an original house (r21456)
[NewGRF] A NewGRF with incomplete string codes at the end of a string could cause invalid memory reads (r21433)
The server did not check for the paused state when allowing to execute commands [FS#3771] (r21429)
Vehicles could be built while the game is paused. Now you can enable or disable that with a setting, which replaces the build-while-paused cheat [FS#4021] (r21428)
Purchase lists were not invalidated when using 'resetengines' (r21374)
Fields were not cleared under snow though they were intended to be [FS#4283] (r21367)

[NewGRF] Custom station foundations using the 'simple foundations'-method did not draw any sprite for WSE-slopes when there are foundations on both neighboured tiles in the north. As there must be at least one sprite to provide the correct offset for the groundsprite draw the (empty) default foundation sprite in that case [FS#4246] (r21262)
The main menu error messages would not show when you had an error message open in the game while whatever triggered you to go back to the main menu (r21255)
Rescanning AIs did not 'forget' removed AIs [FS#3952] (r21250)
Upon rescanning AIs the new AIs would (after some time) show up in the AI list but you could not select all (r21246)
[YAPF] Road vehicles not finding the nearest depot in some (corner) cases [FS#4130] (r21229)
[NewGRF] The specs' cargo strings and OpenTTD's use of the clashed. Provide properties so NewGRFs can provide cargo strings tailored for OpenTTD while retaining (some) backward compatibility [FS#4172] (r21224)

[OSX] Finding a fallback font failed when compiling for OSX 10.4 as it tried to match also OpenTTD-specific control characters [FS#4001] (r21197)
Use non-interactive randomness for townnames on map generation, so they are controlled by the generation seed as well [FS#4226] (r21192)

Do not use the maximum track speed where the maximum vehicle speed is meant (r21107)
Display the real maximum speed for aircraft instead of always using the engine value (r21096)
Aircraft speed would ignore callback 36 result when it is greater than the engine speed (r21094)

When using non-smooth or NewGRF-economy changing production rates does not work, so allow changing the production multiplier instead (r20901)
The station with the second highest rating was doubly penalised when distributing cargo. Now the penalty is completely removed and the granularity/precision of the distribution in increased by using fractional cargo. This should make competing stations less all-or-nothing [FS#3637] (r20857)
Make sure (gradual) loading is properly terminated for consists with multiple cargo types. Do not stop loading if the timetabled wait is not over yet [FS#2534] (r20843)
Place less trees at once when planting random trees at the scenario editor [FS#4094] (r20829)
Do not use new game settings when creating many random towns/industries at the scenario editor [FS#4094] (r20712, r20711)
Keep _current_company and _local_company in sync during GUI operation [FS#3804] (r19933)
When building a lock, do not add the cost of building canals if they are already built, pay for clearing the other tiles and do not add the first bridge type's cost to aqueducts (r19719, r19718, r19717)

Do not consider the text direction character when searching for missing glyphs (r21007)
Chat/console messages got sometimes messed up due to LTR names in RTL translations and vice-versa [FS#3746] (r21006, r21004)

No (proper) savegame conversion was done when _date_fract got a new value range (r20592)
Autoreplace failed while attaching non-replaced wagons to the new chain, if to-be-sold-engines would become front-engines and the unitnumber limit would be exceeded (r20583)
Autoreplace can trigger an assertion when at the vehicle limit [FS#4044] (r20582)
Go via station and go via waypoint behaved differently when a train went back to the same (unordered) station again [FS#4039] (r20580)

For docks 'facing' north, i.e. having the watery part a the northern side, the station joiner had an off-by-one to the north w.r.t. the station spread against the actual other (correct) building tools [FS#4022] (r20438)
Make snow on bridges depend on bridgeheight and make snowyness of bridgeheads depend on the tileheight at the entry [FS#3947] (r20424, r20423, r20422, r20421, r20420)

[NoAI] Clarify the documentation for AIBaseStation::GetLocation (r20238)
Refit costs from refit orders are subtracted from the vehicle yearly income [FS#3988] (r20234)
Road vehicles could be dead locked with one way roads. This allows one wayness to be removed if there are vehicles on a tile; it does not allow you to add one wayness to roads that have vehicles on them as it makes turning vehicles jump [FS#3961] (r20230)
'Service at nearest depot' behaved the same as 'Go to nearest depot' [FS#3986] (r20229)
Depot did not become unsnowy, when snowline rises [FS#3976] (r20224)

If after loading a savegame (including intro game) one tried to save a game (including autosave) and that failed (very) early on because it could not open the file for writing all pointers would be converted to NULLs which then causes corrupted game states [FS#3876, FS#3887, FS#3920, FS#3923] (r20087)
gitignore and hgignore had more missing/wrong entries (r20078, r20033, r20031)

Feature:
Translated desktop shortcut comments (r19884)
Change:
Name invalid engines, cargos and industries 'invalid', if the player removed the supplying NewGRFs, hide invalid engines from the purchase list (r19879, r19877)
Fix:
When 'pause on new game' is set, pause the game before CleanupGeneration() to avoid conflicts with concurrent GUI code [FS#3857] (r19934)
Pay for the rail/road when constructing tunnels, bridges, depots and stations [FS#3859, FS#3827] (r19925, r19887, r19881)

Allow loading savegames from the console without specifying the ".sav" extension, i.e. make it consistent with saving savegames from the console [FS#3761] (r19885)
Dropdowns did affect positioning of new windows because they were not yet removed when the new windows were positioned [FS#3812] (r19883)

Kicking clients by IP did not work [FS#3784] (r19818)
Compilation with MinGW GCC 4.5.0 and UNICODE (r19787)
If a waypoint is immediately followed by a path signal a reservation would be made from that path signal before the waypoint is marked passed. As a result the order to go to the waypoint is used to reserve the path after the waypoint and as such trains get lost [FS#3770] (r19784)
NULL pointer deference when testing relative scope *action2 on an unbuilt engine [FS#3828] (r19782)

Try harder to find a suitable font that can be loaded, i.e. while searching for a suitable font test whether you can open it [FS#3740] (r19753)
Make sure the chat area fits in the default window size; if you want it larger, you can always change/override it in the config file [FS#3798] (r19751)
[NewGRF] Industry var 0x43 is not 'safe' during callbacks 22 and 38 either (r19750)
[NewGRF] Possible divide-by-zero if a NewGRF checked industry var 42 while the production level was 0 (r19749)

Add rail speed limit to land area information window (r19556, r19434)
Added:
[NoAI] AIRail::GetMaxSpeed(RailType) to get the speed limit of railtypes (r19591)
Changed:
Sync Debian packaging updates from Debian, but keep building a single package (r19572)
Fixed:
Crash of a dedicated server if the null blitter is overridden and (after a while) there is no company 0 on new year anymore [FS#3749] (r19664)
In rare cases, update of signals could be missed (r19663)
Various improvements of command handling, missing error messages (r19658, r19657, r19656, r19655, r19654, r19637, r19633, r19621, r19616, r19605, r19604)
Industry generation failed for large maps and lots of industry types (r19652, r19643)
When a company is sold, move connected clients to spectators [FS#3745] (r19651)
A client would not be properly moved when moved while joining, e.g. when entering a company's password. This caused the client to be in the wrong company (according to the rest of the clients) and the client being kicked on the first command [FS#3760] (r19648)
Trains loaded above the original IDs did not have a default railtypelabel assigned to them, causing them to be unavailable. Could cause desyncs if the multiplayer game was not started from a savegame [FS#3768] (r19647)
Do not allow building cacti outside of the desert or rain forest trees outside of the rain forest area. This to prevent people from thinking planting rain forest trees makes the rain forest bigger and thus adds more place to build a lumber mill [FS#3728] (r19644, r19635, r19634)
Desync when taking over companies (r19636)
Chat message caused glitch when rejoining a network game [FS#3757] (r19629)
Desync when a command is received and in the queue while a client starts joining, i.e. save the game state. This can happen in two ways: with frame_freq > 1 a command received in a previous frame might not be executed yet or when a command is received in the same frame as the join but before the savegame is made. In both cases the joining client would not get all commands to get in-sync with the server (and the other clients) (r19620)
Company related graphs were not updated correctly after changing the company colour [FS#3763] (r19615)

Desync debugging; false positives in the cache validity checks and saving/loading the command stream (r19619, r19617, r19602, r19601, r19600, r19596, r19593, r19592, r19589, r19587, r19586)
Presence of online content was not properly updated after download due to duplicate slashes in the path (r19600)
[NewGRF] Setting industry prop 0x24 to 0 caused empty station names (r19590)
Crash when pressing 'h' (non-stop) in the order window of a ship or aircraft [FS#3744] (r19584)
Graphs were not properly updated when going toggling keys (i.e. companies) (r19574)
The timetable button was not automatically raised [FS#3739] (r19571)
[NewGRF] Possible buffer underflow in NewGRF string code (r19569)
[NewGRF] Do not return a random colour for unowned industries in var 45; TTDPatch does not seem to set the colour data in that case either and it could lead to desyncs (r19566)
Window::OnResize() was not always called while resizing a window causing incorrect windows [FS#3730] (r19563, r19558)
Bridge build error message should not show the same message twice (r19560, r19559)
[NewGRF] During NewGRF loading, store rail type labels in temporary data and process after loading has finished. This avoids deactivated rail vehicles being reactivated if the climate property is set after the rail type property (r19557, r19502)
Improperly scaled cargo payment graph when having lots of cargo (r19550, 19543)
[NewGRF] Properties set before property 08 (house, industry, industry tiles) should be ignored, not trigger the NewGRF to be disabled [FS#3725] (r19547)
Sorting industries by production was broken for NewGRF industries (r19538)
Vehicle details window did not resize correctly after refitting a road vehicle to a longer variant [FS#3720] (r19533)
Prevent drawing industries disabled at the smallmap as land tiles when they are built on water (r19523)
Tunnels, bridges and roadstops are build with only one roadtype (r19506)
Remove same_industry_close setting did not do what it said and caused NewGRF trouble (r19499)
Keep number padding intact when cloning vehicle names [FS#3710] (r19498)
[NewGRF] Bytes and words get sign-extended for temporary/persistent storage (r19497)
Stop reducing the size of the vehicle list after selecting a vehicle with a long description (r19480)
Implement custom sound effect for helicopter take-off [FS#3668] (r19364)

When loading a savegame created with a house NewGRF without that NewGRF available all houses became tall office blocks (r19435)
Limit rail clearance earnings to 3/4s of rail build cost, to avoid money making loophole when rail build cost is less than rail removal earnings (r19433)

One could not level the whole map anymore at once (r19392)
Only show the 'No AIs available' error message when explicitly changing the number of AI opponents [FS3676] (r19389)

New in OpenTTD 0.7.0 RC1 (Mar 16, 2009)

Feature: Pop up the AI Debug Window if one of the AIs crashed and show a message that the user should report the crash [FS#2728] (r15708)
Feature: Allow the number of towns that will be generated in the generate world window to be customized [FS#2672] (r15695)
Fix: Enabling freeform edges could cause submarines to get stuck on land tiles (r15733)
Fix: Centering on a vehicle did not respect its z coordinate (r15725)
Fix: Do not show passenger-/mail-capacity if the aircraft carries only cargo (r15705)
Fix: Blame NewGRFs returning inconsistent information in purchase-list/after building before users have a chance to blame OpenTTD for incorrectly autorenewing/-replacing [FS#2595] (r15701)
Fix: Just sell the old engines after autorenew/replace. Do not bother about trains exceeding the trainlimit, which will be sold anyway [FS#2721] (r15692)
Fix: Do not crash when the generate map does not contain a suitable location for a town [FS#2720] (r15689)
Fix: Do not crash when someone substitutes the "map generation" sprites with garbage [FS#2720] (r15685)
Fix: Vehicle images would be determined during the process of moving the vehicle which means that only the (orientation) data for the vehicles in front of it is valid. Now the data for the vehicles behind the vehicle are valid too [FS#2546] (r15677)
Fix: It was possible to remove rail tunnels/bridges and aqueducts build by rival companies [FS#2718] (r15667)
Fix: Sorting of engines in the purchase list did not use the same numbers as the GUI showed, e.g. articulated parts were not taken into accound when ordering by capacity [FS#2689] (r15666)
Fix: Handling of aircraft crash counter did not take account of the reduced number of calls (from 6 down to 2) to the aircraft event handler, resulting in crashed aircraft taking three times longer than they should to clear. Compensate by increasing the counter by 3 on every call instead of 1 (r15665)
Fix: Growing of vsize as (some) threads were not properly released (r15663)
Fix: Do not mark a company as having ratings in a town when querying the cost of a command (r15662)

New in OpenTTD 0.7.0 Beta 1 (Feb 17, 2009)

New features:
Make it possible to have multiple windows with edit box open simultaniously
Add ability to select which base graphics set is used from the Game Options window. The change takes effect when the window is closed. This option can only be used from the intro menu, as reloading graphics during a game may cause issues
Do not draw superfluous catenary wires
Add option to group and subtotal expenses list in the company finance window
Allow moving clients between companies/spectators by the server and the clients themselves
Native support for Transport Tycoon (Original) savegames
Allow terraforming of the tiles at the edges of the map
[NewGRF] Allow a grf to customize house name via callback 0x14D, during Tile Inquiry process
Downloading content from a central server (content.openttd.org) where authors can upload their NewGRFS/AI etc. This should make joining servers that use only NewGRFs that are distributed via this system easier as the players can download the NewGRFs from within the game. It should also make it easier to see whether there are updates for NewGRFs and make the necessary updates
Add support for IP range bans using CIDR notation
An AI framework so people can write their own AIs. This also removes the old cheating and heavily broken AI
[NewGRF] Support var 0x45 (curvature info) also for road vehicles
[NewGRF] Automatically set last engine ageing year to the last 'introduction year plus half model life', to allow engines later than 2050 to appear
Distant joining of stations
Advanced setting to keep various building tools active, which are usually closed after placing an object
Remove the window limit, but leave a configurable limit on the number of non-sticky non-vital windows
Allow road vehicles to move multiple steps in a tick (code based on train movement code) and add support for RV prop 15. This gives RVs a maximum speed of 318mph instead 79mph. This only implements higher speeds, not 'realistic acceleration'
Automatic reversing in front of block signals can now be disabled by setting pf.wait_oneway_signal respectively pf.wait_twoway_signal to 255
Few (optional) optimisations to making (initial) orders; like keeping goto selected
Make the road grids of town match, when all are using the same road layout ofcourse
Pressing CTRL while dragging to build a bridge builds the last built bridge type if possible
Make the date format for default savegame/screenshot names configurable
Allow scrolling with the left mouse button pressed (if enabled). Primarily useful for systems with touch screen
Allow up to 15 companies
Allow up to 255 clients in multiplayer games
When the chosen language is not supported by the current font, try to find a font that does and use that instead
[NewGRF] Action0Industries property 24 (industry supplies default name for nearby station)
Non-destructive autofill with option to keep waiting times
Stop-in-depot order; after this order you have to manually start the vehicle again (or sell it)
Arrow key scrolling in the server list
Initial support for handling bidirectional scripts and connecting Arabic characters
Allow sorting vehicles by remaining life time
Ability to reset name to default/automatic value (for vehicles, engines, towns, groups, stations, waypoints, managers and companies)
[NewGRF] Add Variational Action 2 Variable 0x47 for houses, Coordinates of the house tile
Allow overriding the palette of the base GRFs. This way you can play with NewGRFs made for the Windows palette with the DOS palettes base GRFs (and vice versa). Note that for this to work correctly ALL NewGRFs must use the same palette; mix and match is not yet supported
Double click to join selected server/company
Allow both the German as well as non-German toyland graphics as "correct" and official graphics
Allow people to create their own base graphics easily and without requiring code changes
[NewGRF]: Add support for property 0x13 for Bridges. In other words, one can now specifies a 16 bits cost multiplier
Make it possible to choose between the DOS and Windows graphics packs while retaining the possibility to override the palette
Increase the size of the console backlog. Now it'll only remove backlog items when there are more than a threshold and when they are there longer than (another) threshold
Make it possible to filter list_patches output like it's done for other list_* console commands
Path based signalling
Show [total-]cargo info in depot when [ctrl-]right-clicking on vehicle
NewGRF presets, selected by a drop down list in the NewGRF window. Presets are saved in the config file
Add a few extra columns with information to the server list
[NewGRF] Add var 65 in Variational Action 2 Variables for Houses
[NewGRF] Implement var 63, variational action2 variable for Houses. Or, in more simple terms, the check for the animation frame of nearby house
Aqueducts
[NewGRF] Add var 0x69 for industries, long format construction date
[NewGRF] Add long format introduction and maximum construction year for house
[NewGRF] Add access to current long year and date from Action 7/9/D and VarAction2 (23/24 or A3/A4), and add access to (long format) building year, in Variational Action2 Variable 49 for Vehicles
Splitting of the main toolbar when the resolution becomes very low so the buttons are still visible and useable
Make news messages use a linked list instead of a moving circular buffer. This makes it possible to store more news messages in the history
The number of news messages is reduced by removing every news message that is a configurable amount older than when it would not be shown in the newspaper popup/ticker, which is e.g. a month for industry production changes and half a year for subsidy offers. As a result the more important messages will stay longer in the message history (if longer than 30 messages)
Allow to have more than only two airports per town. The number of airports is now controlled by the noise each of them generates, the distance from town's center and how tolerant the town is (13226)
Introducing the so called 'engine pool' which primarily removes the fixed engine type limits and also happens to allow (with the patch option 'dynamic_engines') multiple NewGRF vehicle sets to coexist
[NewGRF] The ability to play NewGRF sounds for industries and stations
[NewGRF] Add some support for NewGRF station animation
Sorting vehicle lists by road vehicle/train length
Conditional 'skip/jump' orders
Ability to send a vehicle (using default orders) to the nearest depot
Ability to force a vehicle to not load or to not unload at a station
Four different non-stop types, individually selectable per order. Replaces "TTDP compatible order" setting
Three different load type in a single game instead of two. One can choose full load all and full load any instead of full load being governed by the "full load any" patch setting
Financial and Player Selection Face windows are now remembering their position when toggling sizes
Show what cargos a station could be supplied with
[NewGRF] Add random action 2 type 84. For vehicles only
[NewGRF] Add support for var A2/22 for action 7/9/D: Difficulty level
Add +/- toggle buttons to station cargo waiting list to show/hide the detailed transferred cargo information
Open the time table when pressing the order button while pressing the CTRL key
On Screen Keyboard for input fields so someone without a keyboard can enter text too
Changes:
When checking for unique names, compare only with manually set names
Apply the 'warn if train's income is negative' setting to other vehicle types, too
When loading games in "network" mode use the start date of the save game for the server and all clients when loading the NewGRFs instead of the current date. Prevents desyncs caused by action 7/9s skipping parts of the GRF based on the date or some other variables that can differ at NewGRF load time
Only say a engine/vehicle is refittable when it can be refitted to at least two cargo type or when it has subcargos
[NewGRF] Since our NewGRF handling is better than it used to be, disable a NewGRF if unexpected sprites are reached
Fixed:
A town could build a statue under a bridge
Multiple vehicles could be filling the timetable and only the data from one vehicle would be taken. Now only allow one to be filling at a time
When testing for parallel road two tiles away, do not move more than one tile along the road
[NewGRF] The subcargo returned by vehicle variable 0x42 should be the most-common-subcargo of the most-common-cargo. If nothing is transported 0x..FFFF00 should be returned
A tram circling around in a depot did never actually 'enter' the depot
Changing town road layout in-game caused ugly road networks
Company could never have auto-assigned colour 0 (dark blue)
Deadlock (with wide fonts) or desync when generating manager name
Close all windows *before* starting a new game/loading a game instead of doing that as one of the latest steps of loading the game. This caused, in some cases, the NewGRF settings to be reset when the game was already loaded resulting in instant desyncs when joining a network game
Aircraft could be 'loading in the air' or have zero speed while in air after converting old savegames
Tile error location not reset when leveling land causing a tile to be highlighted when there was nothing to flatten
Signs with sign 'Sign' were lost when converting from TTD savegames
[NewGRF] Add support for 8 byte action7/9 data, used as a mask for GRFID checks
[NewGRF] Keep industry variables 8E and 8F in sync with 93, when changing production using results 0D, 0E or 0F of callback 29 or 35
[NewGRF] Disable a NewGRF from loading if it contains multiple Action 8s
Wrong defaults for service interval when switching between service interval in days and service interval in percentages
[NewGRF] Building new station parts did not allocate a new station spec effectively breaking variable 41. This was due to the limited number of station specs that we can have per station. This fix makes newly build station parts create a new spec until one cannot allocate new station specs anymore and it'll revert to the old behaviour (sharing station specs)
[NewGRF] Station specs did not get deallocated when building a new station part over them
Sharing/cloning/inserting of orders that the/a vehicle (in the shared list) cannot go to (wrong station type etc)
The "animation state" of the bubbles was stored in a variable that was not stored in the savegame. Using a variable that gets saved in the savegame solves the desync and makes it a bit clearer
Abort dragging of vehicles in the group window when they are deleted
Do not unnecessarily reset the cursor, when a different vehicle is dragged
[NewGRF] First create all articulated parts of roadvehicles, then call callback 36 capacity, also call it for all articulated parts
Overflow of number of orders per vehicle
Off-by-one causing possible out-of-bounds reads
In an MP game in SP mode no company would go bankrupt. Furthermore companies that passed the "bankrupt" period (4 quarters) would not go bankrupt when loading the game back in MP. Now any company that is in MP or not "currently controlled by the player" in SP will bankrupt
Do not let any disaster vehicle (Helicopter or Airplane) target invalid industry
Memory leak in Action 0x0F (new town names)
Writing a single char to the config file caused reading outside a buffer
First transfer the whole load of a vehicle chain to industries before triggering any processing. This reduces callback usage and resolves critical rounding errors when using input-cargo-multipliers instead of production callbacks
Zeppeliner (disaster) should target st->airport_tile, not st->xy
[NewGRF] Gradual filling graphics were not chosen according to the NewGRF spec
[NewGRF] Check sprite size when executing action 6
[NewGRF] Property 7 and callback 12 were broken for aircraft. Now callback 12 is properly called also for 'mail'. If the callback is not used, 'mail' uses 1/4 of property 7
Possible stack corruption when reading corrupted sprites
[NewGRF] Return the current year as construction year for unfinished houses
[NewGRF] When callback 1E fails, use the standard random colour
The company ID is off-by-one with respect to the rest of the GUI in the cheat window
The range for kicking/banning clients is based on the maximum number of clients, not the maximum number of companies
Allow capacity callbacks (15, 36) to return zero capacity
Crashes when a NewGRF sends an invalid string
Order pool seemed to look full when it was not as it only checked whether it was possible to allocate a new block of pool items instead of checking for free pool items
Do not deliver cargo to industries not inside station catchment area
Allocate stub (empty) sound entries when loading an empty/corrupt/incorrectly sized sample.cat instead of making valid NewGRFs fail to load
Make sure trains stop at the end of a station; a 3/8th length train did stop 2/8th of it's length too early causing a 63/8th long train not to fit in a 4 tile station
Small possible chance of desync due to sorting on pointer instead of by (station) index
When a road stop gets moved make sure to update the destination of RVs going to that road stop
Support for spaces in directories passed to ./configure
Trains would sometimes move one time too often/little when moving from diagonalnon-diagonal tracks
Balance the monthly random industry changes, by introducing a daily random industry change
Save the palette of the loaded NewGRFs in the savegame, so joining with a server using Windows palette will make a client with the DOS palette do palette conversion and (thus) not cause a desync
Glitches (alignment issues/inconsistent vehicle graphics) in original graphics
One could not get a list of vehicles sharing an order when the number of orders was 0; you could see that the vehicles had a shared order though
Various assorted autoreplace issues/malbehaviours
The autoreplace gui showed vehicle types for replacement which CmdSetAutoReplace() did not accept
Automatically recalculate inflation if NewGRFs are changed and cargo types are added, so that cargo payment rates are correct
