This thread has now been closed to direct all further updates about this service release onto the new Beta release thread:
For anyone who has been commenting on this thread, feel free to continue the conversation in that new thread.
Alpha service release: Xamarin.Android 18.104.22.168, bug fixes for 22.214.171.124
Reason for release: Bug fixes for the 126.96.36.199 Stable Channel release on April 29.
NOTE: Alpha 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 regressions have been fixed compared to the current Stable version?" and "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.

Partial workaround: uninstall the Test Cloud integration: https://bugzilla.xamarin.com/show_bug.cgi?id=29680#c2.
