Bug Fixes

Mobile Vision operation is restored in Google Play Services v9.2. Users with the new version will be able to download the required files and make use of application features powered by Mobile Vision. The Google Play Services update also includes a configuration update as part of the fix for Mobile Vision. Normally this is updated once every several days, but it will also occur on phone reboot (though this it is throttled, so this is not guaranteed to update the configuration). Since file download errors can still occur (e.g. if there is insufficient storage on the device), we advise Google Play Services developers to call FaceDetector.isOperational() or BarcodeDetector.isOperational() to check for detector readiness and degrade feature operation accordingly.
