You can now get Windows Vista Beta 2 and a new drop of WinFx (Beta 2/RC0).
This version of WinFX has a new Go Live license attached (the first since January). There's enough new since January that you'll want to make the jump to the May bits.
If you want to use Infocard, this is also the drop for you. This is the first broadly available build that has Infocard bits that work with IE7.
Find both Vista and WinFX here.
