Updated versions and test parts are available through my fork at
https://github.com/EEMLLC/GGFlexThe main is locked because the original lead dev used a third party 'version locker' on all the files for added security and to prevent unauthorized hijacking of the project.
Ironically I just figured out how to bypass it a couple weeks ago, but I still can't do anything with the wiki and need to push all updates to the project at once through GitHub's "Release" system, which means I'm trying to get everything 100% tested and functional before uploading.
There hasn't really been an official release since the 2.0a. The 2.1 consisted of a handful of optional quality of life parts, and the test parts for 2.2 are just minor structural changes while we finalize testing/updating all the parts.
Should have a post regarding 2.2 up in the Announcements section on here later tonight or tomorrow with the changelog and release package to follow (still all on GitHub... probably on LBRY and other platforms later this week)
