Ok, i've been stuck in the dark ages! For the last 10 (ish) years i've been using AS4 (4.18 SP2 infact) which just worked, always, without bugs or errors, on an old WinXP machine.
So, now i'm retiring that machine, and should probably drag myself into the current decade, and swap to AS7. is there some easy guide to how to do that, whats different and what pit falls to avoid?
There's loads of marketing guff about "software frameworks" and all that jazz, but what i really want is a basic "this is what has changed" type guide?
