I’m not a “pro” whatever the hell that might mean. Actually the use of that term is quite frankly meaningless. If you mean that you earn your entire living from recording the music/spoken word of others then you might have a point. However I suspect that many “pro’s” stretch that point to a considerable degree.
For the sake of argument then, to be a professional would suggest a certain reliability. For instance if I went a Lawyer I would expect them to know the area of law they specialised in. Likewise a plumber should be able to do the job and cope with whatever problem is thrown at him. I would certainly be fed up if I went into a studio and had to wait for an engineer to sort out software problems. Taxi drivers have to drive cars that have a record of reliability. To use the latest update on a session is asking for trouble. You have to put the time in to troubleshoot the new version and not introduce it to your clients until you are 100% happy that you know what it can and can’t do.
Things go wrong in a studio - it happens. But if it goes wrong because you have not done your research then that is on you.
I have done a session recently and it was clear that I knew more about Cubase than the engineer, but because he knew exactly what he was doing and how to use the hardware and software at his disposal he produced a lovely recording and his client was really happy. Also it was a pleasure for me to be playing and be able to concentrate upon what I was there for.
What does this have to do with the frequency of updates?
Well we all have to balance what we are going to get out of it. For me as someone who enjoys the process of creating music and the learning when it comes to software, am quite happy to take the risk. For “pros” to complain about the difficulties it entails and the professional consequences, then I would just say be more professional.
