Or just check Canon Rumors from time to time! With all the fuss about FW update issues, seems like checking in, letting things play out for a few weeks or a month, might be better than wishing you could rollback to an earlier version.
In other words, what's the hurry?
Personally, I've never had issues, but all the moaning and groaning has me holding off on one R5 until the anticipated end-of-March update, which I'll continue to hold off installing until Viggo gives his approval!
