A new update to the Google Play Store app with version 4.1.10 is rolling out following the big 4.1.6 refresh from two weeks ago, just before I/O. As far as I can tell from a quick teardown and playing around, this is a minor update. All the important changes happened in the previous release, so 4.1.10 is likely a bug fixer. That said, if you see something I missed, please drop a line in the comments.
Update: 4.1.10 fixes the severe battery-draining location bug introduced in Google Play Services recently, which was especially painful for HTC users. Ron looked into it and found that it downloads a Network Location Provider patch for Google Play Services, though I'm puzzled why Google didn't just update Play Services itself.
