Yep, a beta, which is also available in the discord. But this version is a lot more stable than the version before. I suggest you to create a backup of your worlds, yet there aren't any reports with worlds disappearing. There's is still some stuff missing for the 3.3 release and do not expect, that every new feature will work flawlessly. Send me bug reports if you find any, like always.
