Now that most of the critical issues have been worked out of Android 5.0 Lollipop, most of the releases are going to center around cleaning up less pressing oversights and taking care of bugs. However, it seems that we're still not quite through with the device-specific fixes as an update is now rolling out to the 2012 Nexus 7 (Wi-Fi), codenamed Grouper. No official changelog has been posted, but Al Sutton has compiled a list from the AOSP commits, giving us a pretty good insight into what's new.

Android 5.0.1 began rolling out to devices and AOSP just a few days ago, and now we've got a changelog from Al Sutton to give us some insight into what has changed. This is the first version bump since the Android 5.0 landed, putting an end to the initial stage of build releases, which are often used to fix hardware specific issues and catastrophic bugs. There are still some fixes for individual devices, but some of the bigger bugs have been squashed, as well.
