I will close this thread for simplicity. Feel free to discuss any issues with these new builds or the previous XamarinVS 126.96.36.1997 and Xamarin Studio 188.8.131.52 builds directly in the current Stable Channel release announcement.
This release adds essential compatibility support for deploying to iPad Pro devices and simulators from Xamarin Studio and Visual Studio. The release also includes a candidate fix for Bug 36185 that was causing Visual Studio hangs when loading or working on Xamarin.Android projects.
There are a few remaining known issues related to iPad Pro apps with this release. Of special note, Xcode 7.2 beta is required for iPad Pro icon sizes, and iPad Pro launch image sizes are not supported by Xcode itself.
Please see the Release Blog post for additional details.
