What WinSDK files changed in VS2008 SP1?

Wondering what changed in the WinSDK components that ship in Visual Studio between VS2008 RTM and VS2008 SP1? Chris Hubbard, an SDET on the Windows SDK team, has posted a list of new files in VS 2008 SP1 and also the files that have changed. See WinSDK in VS2008 SP1: what changed? For starters, only the tools were updated in the VS 2008 SP1. The Windows headers and libraries did not change. The headers and libs are the same as those that shipped in the Windows SDK for Windows Vista Update and .NET Framework 3.0.
