Hey,
I really love Freerapid for long time. It looks like development was terminated, after no update for few years and I am glad you adopt new Java version and made beta release.

No to the topic.
Don't you plan to make public github / gitlab repository and change to git from svn?
You provide source code for downloading, and svn repository, but svn is little bit outdated and github/gitlab provide nice features for people helping with code, issues, ci, etc..

I second the request for Github open source. This project deserves to have new and continued life. It's a valuable resource for many.
