Draft release notes

Here's what I'll plan to include for this PR in the release notes:

  * [GitHub 3784](https://github.com/xamarin/xamarin-android/issues/3784),
    [GitHub 4471](https://github.com/xamarin/xamarin-android/issues/4471):
    An outdated version of the Mono Shared Runtime package was sometimes left on
    target development devices and emulators after Xamarin.Android version
    updates.  This could result in unexpected behaviors in Debug configuration
    apps until the old shared runtime was manually uninstalled.

To suggest any changes, feel free to reply on this PR. Thanks!
