VASSAL 3.3.0-beta3 Released

The VASSAL Team is happy to announce the release of VASSAL 3.3.0-beta3.


  • This is a beta release. Things may be broken which worked in 3.2.17. If you find a bug introduced since 3.2.17, please report it.
  • If you save a module in VASSAL 3.3, you will NOT be able to open it afterwards with VASSAL 3.2. We recommend keeping a backup copy of any pre-3.3 modules you plan to modify in 3.3 until you've verified that everything works to your satisfaction.
  • Some modules containing custom drawing code may render incorrectly on HiDPI displays. If you are the maintainer of such a module, let us know and we can advise you about what needs updating for 3.3 in your code. (We are aware already that VASL has this problem and are working with its maintainers to update it.)


New in 3.3.0


  • 12557, 12613: Compatibility with Java 9+: VASSAL 3.2 would not run with anything newer than Java 8. VASSAL 3.3 now requires Java 11 or later.
  • 12558, 12724: Bundle Java with VASSAL: The Mac and Windows packages now include Java 14. It is no longer necessary to install Java separately when using one of these packages.
  • 12559: HiDPI support: VASSAL now has support for displays with a high pixel density (e.g., Retina displays). On such displays, you should now see correctly sized interface elements and sharper image rendering.

Bug fixes in 3.3.0-beta3:

  • 12732: Use all available rendering hints for text
  • 12731: javax.sound.samples.Clip fails to convert WAV files it can play

Bug fixes in 3.3.0-beta2:

  • 12579: Don't bundle Java on Linux

Bug fixes in 3.3.0-beta1:

  • 12556: Mass Piece Definer does not sort image names

For changes prior to 3.3.0-beta1, see the change log.

Minimum Requirements

VASSAL 3.3 requires Java 11 or later.

The Windows and Mac packages have an appropriate version of Java bundled with them, so there is no need to install Java separately on those operating systems.
