What changed/added:
- The profiler has been improved, and now provide memory profiling as well
- The emulator has a couple improvements to make development and testing better:
- The RTM build (build 7720) is used by the emulator, providing you with confidence that the code you write will work on Windows Phone 7.5 retail devices
- A screenshot capability is now also built-in, allowing you to quickly capture images of your app in action

- NuGet is now supported in the free Visual Studio 2010 Express for Windows Phone SKU, allowing you to easily keep your add-ons up to date
- The completed Marketplace Test Kit enables you to test your app for certification on your machine, running the same technical certification tests that the Marketplace team runs, which should dramatically improve your chances of passing the first time
