Stable Release: Cycle 9 SR0 with Xcode 8.3 Support

We are releasing an update to our current stable builds of Xamarin Studio, Xamarin for Visual Studio, and Xamarin.iOS. These new builds offer Xcode 8.3 support, for the Xamarin.iOS SDK and the Xamarin iOS Designer. In addition, we have addressed an intermittent NullReferenceException crash that could occur when canceling NSUrlSessionHandler HttpClient.SendAsync() requests via CancellationTokenSource.Cancel() in iOS projects (53794).

For Visual Studio 2017 users, be sure to update to Visual Studio 2017 15.0.26228.12 or higher to get the new versions of the Xamarin extensions.

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 to let the team know.

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.
