I must have missed the final announcement on this one last month? If you're running Visual Studio 2005 SP1, the additional update needed to resolve some of the Vista compatibility issues is now available (it was in beta previously). This is a separate and additional update for Visual Studio 2005 than SP1. You must have SP1 for Visual Studio 2005 installed before you can install the Vista update.
For more info on the update, go here.
