Google has just released the latest flavour of Android Jelly Bean, which is now rolling out to users everywhere in the form of version 4.2.2.
As part of the rollout, the minor Android 4.2: Jelly Bean update has been pushed to AOSP as build number JDQ39, with files tagged as "android-4.2.2_r1." The update may not be showing on all devices just yet as these sometimes take time, but if you're impatient, you can manually check for Android 4.2.2 via the Settings page on your device.
Android 4.2.2 is a modest update for improved performance and stability, but the custom ROM community appears eager to get their hands on it regardless. Now that the update has landed on the Android Open Source Project, developers like CyanogenMod and AOKP can get to work tweaking their ROMs to support the latest and greatest version Google has to offer.
Android enthusiasts are also eagerly awaiting a post from Android's chief release engineer, Jean-Baptiste Quéru, which is typically posted to the Android Building Google Group shortly after a release hits AOSP.
Finally, a full changelog for the Android 4.2.2 release is also expected, which could detail any small revisions that early adopters might not have noticed.
