Service Pack 1 for the Visual Studio 2010 was released last night. It's now available for the MSDN Subscripters and in few days it should be available for everyone. Grap it while it's hot.

Here's a good summary of the new features and bugfixes.

Personally I'm most interested in the following new features:

  • Support for IIS Express
  • XAML Editor changes
  • Support for intrinsic functions
