Stuart,
thanks, it was in SU last night when I saw your post, just not yesterday morning.
As for the App Store, it doesn't offer me updates for anything that I didn't buy through it. Looking at Aperture there last night, it gave me only the option to buy, and the update section reported all apps up to date. Then after the update it shows it as installed. It's a little schizophrenic at this point, but I guess that's expected given how new it is.
