This is an SDK only updated release (e.g. porting kit and firmware don't change). The major highlights are:
- Updated SDK to support use with Visual Studio 2013 (and experimental support for Visual Studio "14")
- Split SDK installer from Visual Studio support. The SDK MSI now installs only the tools, and reference assemblies (like the desktop versions). A separate VSIX package installs to each supported version of Visual Studio to complete the installation. VSIX packages are available here, as well as from the Visual Studio Extensions Gallery accessible directly from VS.
- Since VS integration is on a per version basis, this new model also supports simultaneous installations of multiple VS versions.
