For the Head/Rack there are perfectly stable release versions available, so no reason to use a beta version in critical applications.
Yes, there are! BUT NO NEW STABLE versions to where pop up messages refer like in Rig Manager. That was the only reason I updated my OS because of RM. I wonder where you have seen a new stable version...!
Wish I had never done that! I'm back now to my OLD OS now and only that one works fine.
