Version 2.23

Version	2.23.0
Release Date	2025-03-23
Author	Albert Ball
Changelog	Implemented Minimum Dwell Times (MDT). MDTs can optionally be set as an additional parameter at locations in the timetable (eg. `08:45;08:50;Patricroft;180` sets an MDT of 180 seconds). Trains will not leave until the MDT has elapsed. If no MDT is set, a default of 30 seconds is used. Note that timetables using the MDT feature will not load in versions prior to v2.23.0. Fixed a bug where the train information window failed to give timetable information for trains waiting to enter the railway. Fixed a bug where the heatmap colours introduced in v2.22.0 were the wrong way round in the 64bit version. Changed the default button for focus to play/pause, rather than exit. This ensures if an error is closed with the enter key, and the key is double pressed accidentally, the sim pauses rather than closing.

Version	2.23.1
Release Date	2025-04-04

Changelog	In terminating a shuttle early to link to a follow-on service the program gave the message ‘no follow-on service’ when there was in fact such a service. When a green route that immediately followed a blue route was truncated from the front the signal at the end of the blue route stayed green instead of changing to red as it should have done.

Version	2.23.2
Release Date	2025-06-08
Author	Albert Ball
Changelog	Timetable error messages that involve illegal events are now more explicit. The event that causes the validator to fail is now given as well as the earlier event. A train that starts with zero speed and is created under signaller control (one that has ‘S’ after the Snt location) remains ‘stopped on signaller’s instruction’ when it isn’t at a named location rather than starting to accelerate. Bug fixed where a train without power that is joined by a powered train still identified as without power so couldn't move.

Version	2.23.3
Release Date	2025-11-28
Author	Albert Ball
Changelog	When erasing track that also has platforms, foot or level crossings or other (blue) locations present the first right click just erases the platforms etc., leaving the track intact with its length, speed limit and preferred direction(s) in place. This makes it easier when only those elements need to be erased, as it saves having to replace the track and reset lengths etc. A second right click erases the track. During operation missed or late passes carry no score penalty (this has been the case for several versions), so the ‘ERROR’ prefix has been dropped in the performance log to better reflect this. A ‘maximum lateness’ entry has been added to the performance log summary.
