I have just made a new release of Robocode Tank Royale 0.37.0, which contains the new Battle Runner 🎉

The Battle Runner API lets you run Robocode Tank Royale battles programmatically from any JVM application — no GUI required. Use it for automated testing, benchmarking, tournament systems, or any scenario where you need headless battle execution.
