A
source code branch and a
beta build are available for running JForum in JakartaEE 10 environments such as Tomcat 10.1. The minimum Java version required is Java 11. This has not been tested as extensively as previous versions, and remains work in progress. But it contains no known bugs, even quite a few bugs less than the last release version 2.8.3.
Please send us feedback if you use it, both positive and negative.
