Reason for release: Hotfix. This is Xamarin Studio 188.8.131.521 plus just the fix for the "Build -> Archive for Publishing" "Disallowed paths ( "iTunesMetadata.plist" )" issue. This build does not include any other fixes from the current 5.9.1 Alpha channel build.
I will close this thread for simplicity. Feel free to discuss any issues with this new build or the previous 184.108.40.2061 build directly in the current Xamarin Studio Stable Channel release thread instead.
EDIT May 11: Correction: the current Alpha channel build also includes this fix. You can currently use either the Stable or Alpha channel to submit apps via "Build -> Archive for Publishing".
