[2023] Any new on when this EXP is ending?

Originally posted by Ben2space: I've been trying to find out myself also. They didn't change much so I'm not sure why 21.2 is hanging in beta status for the last 6 weeks. I cannot find anyone discussing anything except one discussion on how the perma-death is too multiplayer-y.

Internally, it was just updated a few days ago. They need to make sure that the changes in the update aren't going to break any existing saves, and there are a couple of critical bugs that are being difficult to narrow down. Additionally, they may be looking at back-porting a couple of changes/fixes from the Alpha 22 build which requires a bit of extra work.
