We've just released Android Studio 0.8.12 to the canary channel (Note: There are no incremental patches to update to 0.8.12; you will need to download it separately -- and the reasons for that are explained below.)
NOTE: These .zip files do not contain an embedded SDK install. If you have an existing install of Studio which contains an embedded SDK, if you upgrade by installing one of these zips, make sure you copy over the SDK as well.
