Beta Release: 15.1 Beta Preview 2

We are releasing the final Beta preview of our next major release, called 15.1. This release uses a new naming convention “15.1” that more closely resembles the sub-version numbering of Visual Studio 2017. “15.1” in this new scheme matches up with what Xamarin would have called “Cycle 10” under the old scheme.

This release is now available in the Xamarin updater channels and as part of the March 27 update for Visual Studio Preview. Note that the Xamarin version number in Visual Studio 2015 is slightly ahead of the version number in Visual Studio Preview in order to provide early availability of a few additional fixes. Xamarin coordination with the upstream schedule has been evolving across the VS 2017 releases, and plans are underway to synchronize more tightly as soon as possible. Watch for additional news on that topic as the 15.1 release moves into the Stable channel in the upcoming weeks.

Among other changes, these versions include a new experimental Concurrent Garbage Collector option for both Xamarin.Android and Xamarin.iOS.

As this is a Beta build, there are some known issues and the possibility of new issues being found during testing. Of course, additional bug reports are still welcome for these preview versions. If you see any suspicious behavior that you wish to report, please file a quick bug.

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.

Please check out the product release notes to see all the fixes and known issues for this release.
