- Feature: Give more detailed error message when trying to build a too long bridge (r19561) - Fix: [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) - Fix: Window::OnResize() was not always called while resizing a window causing incorrect windows [FS#3730] (r19563, r19558) - Fix: Bridge build error message should not show the same message twice (r19560, r19559) - Fix: Missed conversion to checking temporary data broke rail type setting upon changing traction type (r19557) - Fix: Incorrect speed limit reported for rail depots with original acceleration model (r19556)
