Thanks everyone for the information. That's brilliant. I didn't realise the updater was that sophisticated. I'll switch to openbeta and see how it goes :)
Thanks. So the official release date of any module will always refer to an open beta release?
Should I install both versions (at 120GB+ each I'd rather not!)? Is there any benefit to only installing the open beta? Does the latest stable version mirror the latest beta at time of release?
I've pre-ordered too. Looks great. It might not be a popular opinion on here, but I'd be happy to see more GA stuff (Cessna 152, Piper Tomahawk, etc.).
