This is a medium sized bugfix release. It addresses several of the known issues from the Xamarin 4, Cycle 6 Feature Release. See the Release Blog post for more details.

NOTE: Beta versions have not yet completed the full suite of tests by the Xamarin QA team. That said, customer reports of any regressions (or bugs that are incorrectly marked fixed) are still much appreciated, even if the problem would have eventually been caught during the full QA testing process.

Compatibility notes

(These are the same as for the initial Cycle 6 Feature Release.)

  • [XamarinVS] The Cycle 6 builds of XamarinVS now require Visual Studio 2012 or higher. Following along with the end of Mainstream Support for Visual Studio 2010 by Microsoft, Cycle 6 is not compatible with VS 2010.

  • [iOS] The Cycle 6 builds now require Xcode 7 or higher. For example, attempting to build an iOS app for device using Xcode 6.4 will now fail with "Native linking failed, undefined symbol: ___divdc3".

  • [Xamarin Studio] [XamarinVS] [iOS] [Android] [Xamarin.Mac] Support for OS X 10.9 Mavericks has been deprecated. The Cycle 6 builds now require OS X 10.10 Yosemite.
