ClownerCraft is still running on 1.15.2, this is not the full update.

We are now able to support 1.16 clients, so you do not need to downgrade in order to play ClownerCraft. However all servers are still running on 1.15.2 – so there isn’t access to any new features yet.

Stay tuned for more details about the update in the near future.

PS. You could also even join with an older version of the game, and things would be just fine, although bees may look weird. But you know, technically 1.9.x -> 1.16 clients can join. I’d suggest 1.15.2 for the best experience in Survival/Creative though.
