Changelog

New charts, updated runway calculations, and minor changes

New features

  • New charts/graphs module taken into use:
    • A new modern framework for graphical charts has been introduced to the game interface.
    • As the first step, new "Cost Distribution by Fleet Type" and "Cost Distribution by Engine Group" charts are added to the Fleet Commonality page. This acts as the first "public technical test" of this new charting system.
    • This system will gradually replace the current charting system as pages are updated to the v2.0 UI.

Improvements

  • Updates to aircraft runway performance calculations:
    • Improved aircraft runway performance modelling (takeoff and landing) in the cases the aircraft is runway limited and route payload has to be reduced.
    • The previous version had some inaccuracies especially with landing runway length calculations, but these are now handled better and have less inconsistencies.
    • Generally speaking the landing runway calculation is a bit more restrictive now than in the previous version, but it should be more accurate and reflect real operations better.
    • This update has been implemented to the History and the Future game, and any games which have started or are starting after that. (According to our check of all existing routes in HatF game, only 0.05% of all routes will see small changes of payload limits downwards.)
  • Improved a few aircraft images for better quality based on user feedback.
  • Improved user access control to the game.
  • Further behind-the-scenes improvements to backend systems, development workflow, and testing tools.
  • General overall improvements to code quality and standards, thanks to our new development and testing tools.

Fixes

  • Various minor fixes to dark mode colors in old UI elements based on user feedback.
  • Game time converter did not work on Safari.
  • Minor fix in alliance invitation automatic decline message upon airline closure.
  • Fleet Commonality, Scheduling and Settings pages did not sort alphabetically if manufacturer name started with a lowercase letter.
