Can anyone comment on the differences between this and the Xcode 4 GM Seed 2 that I've been using for the past few weeks? A bit of browsing led to noticing that the version reported on the welcome screen shown in the screenshots section of Xcode's App Store page is the same a the GM 2 version number. Of course they could just be reusing screenshots but I'd love for somebody to check this. Update: I noticed that the download page for Xcode 4 reports that it's version 4A304a, the same as the GM seed.
