Forgive my very belated reply, but I'd like to ask a question about upgrading, and this topic fits.
The "current version" sticky tells us that 3.0 is already available to Pro customers. I picked up my copy of TNet on the Asset Store when I did, and I never quite got around to upgrading, which would have been quite useful, in hindsight. If I do it now, will that count as upgrading to TNet 3 and living happily ever after?
