AOSP recently moved to android-4.2.1_r1.2 tag with a new release build JOP40G.
Changes/Updates are limited only to following projects:
[] platform/build
[] platform/system/core
[] platform/system/extras
[] device/lge/*

I have merged changes from android-4.2.1_r1.2 to linaro_android_4.2.1. I'm in the process of merging r1.2 changes to project specific branches and I'll send out notification to project lists when I'm done.

Regards,
Amit Pundir
