About Greenfoot

What's new in 3.9.0

  • Upgraded to Java 21 including support for new language features.
  • Added code completion for local variables.
  • Fixed bug with compiler errors sometimes not showing.
  • Improved Mac startup speed (especially on new Apple Silicon build).
  • Added Raspberry Pi Linux build.
  • Several Java and Stride editor bug fixes.
  • Fixed a bug where the Windows MSI installer would allow multiple per-machine installations of different versions (in the same directory). Greenfoot 3.9.0 should correctly remove all prior per-machine installations of earlier Greenfoot versions.
