For the last few weeks, Google has been pretty active at delivering various updates. One of the least expected updates surfaced just a moment ago, as our beloved Android has been updated to version 5.1.1. The first device that got the update to Android 5.1.1 is the Google Nexus Player, released alongside Lollipop 5.0. The factory image and binary files required to compile the system are already available on the relevant webpage. Images for other supported devices (hopefully including Nexus 9) should be posted in the next few days.

Android 5.1.1, as the version suggests, is not a major release. Google focused on providing bug fixes, including the infamous memory leak available in Android since version 5.0. We didn't have much time to look into logs to see what exactly has been changed, but the changelog should be provided pretty soon.

If you are a developer and can't wait to get the OTA, you can build the system yourself for supported devices.

repo init -b android-5.1.1_r1 && repo sync

You can also run this command to sync the AOSP sources from scratch:

repo init -u https://android.googlesource.com/platform/manifest -b android-5.1.1_r1 && repo sync
