Beta Preview 2: Cycle 8

We are releasing the second Beta preview of our next major feature release, called Cycle 8. As this is a Beta build, there are some known issues and the possibility of new issues being found during testing.

The issues addressed below are only the highest severity ones, so please check out the product release notes to see all the fixes and known issues for this preview.

The Xamarin team is looking for as much user feedback as possible on these Cycle 8 Beta versions, especially for the iOS 10 and Xcode 8 features. If you see a behavior that looks suspicious in these versions, and if it isn’t clear whether one of the known issues in the release notes matches the problem, please file a quick bug report.

If you notice an error in this blog post or have trouble downloading one of the installer packages, please let us know in the corresponding forum thread.
