Some companies quickly follow up beta testing periods with release versions of the same code, but Sequential doesn't do that often. Whatever Sequential's latest BETA version is will usually be the most stable, bug free, feature rich OS available. If it has been 3-4 weeks since a beta release, I would recommend just downloading and installing their beta, even if you're a person who generally doesn't install betas from other companies.
Sounds like you're good to go @Bigmuff. Congrats on the Pro3 acquisition. It's an amazing synth!
