- Fix: [Win32] Some keypress combinations could be handled twice [FS#2206] (r14363)
- Fix: The ownership of roadtiles was not properly set for very old savegames (including TTD's) making it impossible to remove some pieces of road [FS#2311] (r14359)
- Fix: Desync due to randomly ordered vehicle hash by flooding and road vehicle overtake/following (r14356, r14258)
- Fix: Signs were not updated on company bankrupcy/sell, and thus could have the colour of invalid player (r14348)
- Fix: Delete the RenameSignWindow when 'its' sign is deleted (r14345)
- Fix: Building through the wrong side of a drive through station was allowed [FS#2166] (r13822)
- Fix: Check for vehicle length changes outside a depot (callback 0x11) and give a warning about that [FS#2150] (r13816)
- Fix: Remove the unique_id from the message that a client has joined as it is only exposes the unique_id more than needed (r13714)

- Fix: Checking for train waiting at other side of two-way signal was broken [FS#2162] (r13806)
- Fix: Some revision checking code was unintentionally disabled (r13776)
- Fix: Enforce the validity of a NetworkAction (chat packet) issued by a client (r13775)
- Fix: Selecting non-full length vehicles in the depot gui would place the "mouse pointer" out of the center of the vehicle making it hard to "aim" [FS#2147] (r13759)
- Fix: Possible buffer overflow in string truncation code (r13700)
- Fix: Handle SETX(Y) properly when truncating a string instead of ignoring it and returning a too long string (r13699)

- Fix: Revert changes to multihead engine weight -- the original values were correct (r13023)

- Fix: [OSX] In some rare cases when using an uncalibrated monitor the system colour space could not be retrieved. Show an error when this happens instead of just trying an assertion (r12776)
