This thread has now been closed to direct all further updates about this service release onto the new Stable release thread:
For anyone who has been commenting on this thread, feel free to continue the conversation in that new thread.
Reason for release: Bug fixes for the 126.96.36.199 Stable Channel release on April 29.
May 19, 2015: 188.8.131.52 published to Beta and Alpha updater channels
See the corresponding Alpha release thread (now closed) for the earlier history of this service release: http://forums.xamarin.com/discussion/40279/alpha-service-release-xamarin-android-5-1-2-bug-fixes-for-5-1-0/p1
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.
You can downgrade back to the current Stable version by switching updater channels.
You can downgrade back to the previous Stable versions (from before April 29) by manually reinstalling each old package (see also the article about downgrading). The links to the previous Stable versions are:
This first post will be updated regularly.
Hopefully this thread will help answer "what might break if I update to this release?"
If you find a new problem that is specific to this version, please file a bug report (if this link redirects to the top-level
https://kb.xamarin.com/ page the first time you click it, try clicking it once more).
Please discuss older bugs that are unchanged in this release compared to the previous Stable version in Bugzilla instead.
Of course for questions and discussions about topics other than bugs, feel free start new forum threads.
(The fixes for most of these remaining issues are scheduled to be released in the next service release. The first Alpha versions of that release will be published shortly after this current Beta is promoted to Stable.)
Non-public Bug 28995 - [Android] On certain devices, certain apps crash frequently due to "System.ExecutionEngineException: SIGILL".
Bug 30318 - [Android] Windows only: Breakpoints in PCL projects do not work after cleaning solution, redeploying, and restarting debugging. Partial workaround: delete all the
bin folders in the solution after cleaning.
Bug 30371 - [Visual Studio] [Android] Project Properties display incorrect default values for "BundleAssemblies" and "EmbedAssembliesIntoApk" if they are not explicitly specified. This means that these properties can "automatically" change to incorrect values when you update other properties under "Project Properties -> Android Options". The incorrect values can cause secondary symptoms like Bug 30334 where breakpoints are not hit in the Debug configuration.
Non-public Bug 30057 - [Android] Windows only: the debugger will not be able resolve breakpoints unless "Shared Runtime" is ON and the Linker is OFF (under "Project Properties -> Android Options" in Visual Studio or "Project Options -> Android Build" in Xamarin Studio).
Bug 29326 - [Android] String resources defined in NuGet packages overwrite string resources defined in app project, causing the displayed app name to be incorrect for example. Workaround: avoid using the same string key that is used in the NuGet packages.
Bug 30548 - [Android] Under certain conditions new threads take several seconds to start. This problem seems to be triggered by Xamarin.Insights 1.10. Partial workarounds: downgrade Xamarin.Insights to version 1.9, or remove it entirely.
[Bug 30072](https://bugzilla.xamarin.com/show_bug.cgi?id=30072) - [Xamarin Studio] [Android] Xamarin Studio sometimes crashes with SIGABRT in
gtk_text_view_validate_onscreen() after password is entered during "Import an Existing Key" in "Build -> Archive for Publishing -> Sign and Distribute" workflow.
Non-public Bug 29538 - [Android] Profiling via the graphical Xamarin Profiler ("Run -> Start Profiling") causes the app to crash at startup.
Bug 29731 - [Android]
Android.Bluetooth.BluetoothAdapter.Enable is incorrectly marked as
[Obsolete("deprecated")] for API level 20 and higher.
Non-public Bug 29725 - [Xamarin Studio] [iOS] [Android] Expressions in the Watch window are cleared each time you stop debugging.
