Where is the hotfix for Painter 2021?

The launch bugs are still here, i remember in past versions they release a hot fix and painter became really good, if the past update was the hotfix, i didn't saw a change at all, the bugs are still there, the brushes behave better. But im more worried in tiny details like i cant pull out the panel of underpainting from a group because it stops working.

Can someone give me info if they are going to release one?
