VASSAL has a new User’s Guide! You can view the User’s Guide by selecting “User’s Guide” from the Help menu in any of VASSAL’s components.

The recommended minimum Java version for VASSAL 3.1 has changed. A bug in versions of Java prior to 1.5.0_08 (a.k.a. Java 5 Update 8) prevents some images from loading properly. We now recommend that anyone using a version of Java older than 1.5.0_08 upgrade to at least 1.5.0_08.

Furthermore, we recommend that Windows users in particular upgrade to at least Java 1.6.0_21 (a.k.a. Java 6 Update 21), in order to avoid bugs present in earlier versions of Java. Windows users installing VASSAL 3.1.19 with the Windows installer will be prompted to update Java if what they have is older than 1.6.0_32. After upgrading Java on Windows, you must restart your computer in order for Java programs to work properly.

Please report all bugs, even if they are bugs which you’ve already reported against other versions. We take your bug reports very seriously—they’re the reason we’re able to find and fix bugs.
