- Fix: NewGRF rail continuation would always mark a tunnel on the same axis as connected, even when the tunnel faces the wrong direction (r13734)
- Fix: Assumption that non-north tiles of a house do not have the 1x1 building bit set was flawed with some NewGRFs. This caused the amount of houses to differ, which causes the town radii to differ, which causes desyncs when towns are expanded (r13729)
- Fix: Possible desync on the autorenew settings 20+ game years (i.e. 4.5+ hours) after a company was started (r13718)
- Fix: Any player could construct new companies [FS#2144] (r13716)
- Fix: Possible crash on creating a network packet (r13713)
- Fix: Enforce the length restrictions of company and president name in the commands too (r13712)
- Fix: If the first bridge can not be build for a given length, then none of the other bridges can. Effectively meaning that if someone replaces the first bridge with a bridge that can be only 3 tiles longs then only other bridges that can be 3 tiles long will be buildable, but only if they are 3 tiles long [FS#2100] (r13611)
- Fix: [OSX] 10.5 failed to switch to fullscreen (r13584)
- Fix: Properly count number of non-north housetiles [FS#2083] (r13518)
- Fix: Drawing of zoomed out partial sprites could cause deadlocks or crashes (r13502)
- Fix: Memory leak when NewGRFs got forcefully disabled and they defined GOTO labels (r13675)
- Fix: Crash when drawing a non-real sprite caused by NewGRF interference [FS#2127] (r13674)
- Fix: Disable static NewGRFs when non-static NewGRFs query them in the context of network games. This makes it impossible for static NewGRFs to disable non-static NewGRFs and 'bad' things happening because the non-static NewGRF doesn't know about the static NewGRF (r13576)
- Fix: First determine where to *exactly* build a house before asking a NewGRF whether the location is good instead of possibly moving the house a tile after the NewGRF said the location is good (r13489)
- Fix: Do not crash when resolving vehicle sprite groups with zero sprites (r13397)
- Fix: In the purchase list, CB36 for capacity was not called for the first part of rail and road vehicles (r13385)
- Fix: Town rating was affected even after the test run (r12920)
- Fix: Flood road tiles even when there are road works in progress [FS#1965] (r12919)
- Fix: Do not initialize Station struct with tile=0, buoys will never change that value [FS#1960] (r12915)
- Fix: Game crash when a spectator/server tried to show an engine with no owner when a NewGRF requested a specific variable (r12914)
- Fix: Report reverse sprite status (FD/FE) to NewGRF for manually toggled vehicles (r12910)
- Fix: Slope checking for NewGRFs failed (r12759)
- Fix: Check the TILE_NOT_SLOPED flag of the _north_ tile of multi-tile houses to decide if autoslope is allowed (r12717)
- Fix: Removing road pieces from a town gave you twice the intended penalty [FS#1920] (r12682)
- Fix: Towns could not terraform when inflation rised terraform prices enough (r12564)
- Fix: Do not affect town rating change by the order in which we examine stations (r12561)
- Fix: Make the town rating tests use less memory and much quicker (r12859)
- Fix: Usage of AutoPtr made (trying to) build stuff very expensive (r12857, r12855)
- Fix: Use YAPF for fairly old savegames from before YAPF was introduced (r12845)
- Fix: The industry tick trigger should only be triggered once every 256 ticks, not every tick... Also bail out of the triggers a little earlier if you know they are not going to happen anyway (r12844)
-Fix: allow building 2x2 building on slopes if not explicitly forbidden
-Fix: it was possible to build 2x1 and 1x2 buildings on slopes even if it was not allowed
