Published just a little bit ago on the Android Building portion of Google Groups, Google’s Technical Lead Jean-Baptiste Queru indicated that an update to the Android Jelly Bean version of the OS will be forthcoming to the Android Open Source Project (AOSP). Below is a copy/paste version of JBQ’s post:
We’re releasing Android 4.1.2 to AOSP today, which is a minor update
on top of 4.1.1.
As a note to maintainers of community builds running on Nexus 7:
please update to 4.1.2 at the first opportunity. Future variants of
the grouper hardware will have a minor change in one of the components
(the power management chip) that will not be compatible with 4.1.1.
The build number is JZO54K, and the tag is android-4.1.2_r1.

Normally, the GSM/LTE versions of these updates find their way into the wild first, and then the CDMA/LTE versions follow thereafter. As a Verizon Wireless user, I’m eager to see what the changelog shows the improvements to the code will be. But as can be seen, this update is significant for Nexus 7 users, even though it may not be so for Galaxy Nexus or other Jelly Bean custom ROM users. I’m sure the developer community will be on top of these code changes really quick like.
