Robocode 1.10.0

Version 1.10.0 (04-Jun-2025)

Robocode's code around RobocodeSecurityManager has been refactored to ensure compatibility with Java 24 and newer versions, even after the retirement of the Security Manager in Java 24. Read more here.
Additionally, Robocode remains fully functional on older Java versions, from Java 8 onward.

Changes

• Java 24 support: Implemented new security mechanisms that work with Java 24+ while maintaining compatibility with Java 8+.
• Versioning update: Adopted Semantic Versioning starting with version 1.10.0.

Robocode 1.9.5.5

Version 1.9.5.5 (29-Mar-2025)

Changes

• Robocode cannot run with Java 24, which implemented JEP 486: Permanently Disable the Security Manager.
  • Robocode has its own security manager built on top of Java's Security Manager, which has now been removed with Java 24.
  • Robocode will not start up when running Robocode on Java 24 and newer. Instead, an error message is written out that Robocode does not support Java 24.
  • Fixing this issue requires a big rewrite of large parts of the security mechanisms in Robocode to prevent robots from doing harm on the system and from cheating against other competitor robots in battles.
  • Use Java 23 or an older version of Java instead, or head over to the new platform for Robocode: Robocode Tank Royale.
