At Google I/O this year, we learned that Google Play Services is generally updated on a six-week cycle. As expected, the mighty puzzle piece behind Google's Android services is getting an update starting today that introduces a number of small changes that most users probably won't notice but which may make developers' lives a little bit easier.
Among the changes users probably will notice are some UI tweaks. The Google Settings app has a refreshed header (which is carried through all GMS-bound settings), and Google Play Games has a new dialog for toggling your profile from public to hidden.
