0.27.0

📦 0.27.0 - Lots of bug fixes - 02-Dec-2024

This version fixes various issues, some found when running legacy bots with the [Robocode API Bridge].

🚀 Improvements

• Bot API for .Net:
  • Improved performance of event handling by replacing ImmutableList and ImmutableHashSet with List and
    HashSet protected with lock blocks.
• Bot API for Java:
  • Improved performance of event handling by replacing CopyOnWriteArrayList with
    synchronizedList(new ArrayList<>()).

🐞 Bug Fixes

• Server:
  • #117: Server process consumed 100% of a CPU core even when the game is paused (due to nano timing).
    • Thank you, Tobias Zimmermann, for spotting and fixing this nasty issue! ❤️
• Bot API:
  • #1: Wrapped bot throws an exception. Fixes in both
    the Bot API and Robocode API Bridge caused by the Tank
    Royale Bot APIs.
  • #119: Battle was not starting on Windows 11 and 10 after installing Docker Linux subsystem.
  • Bridged bots run multiple threads after round 2 due to old thread(s) hanging that could not be stopped.
  • Bridged bots could not be restarted as they got a connection error with the WebSocket when restarting.
  • .Net bots sometimes exited when running at max speed without any exceptions occurring.
