Android 4.4.1 source files haven't even rested in the repositories of the Android Open Source Project long enough to get cold, and they're already getting served up by a fresher helping of code. Google has made the Android 4.4.2 files available in AOSP under the release tag android-4.4.2_r1. The platform/build repo confirms that this is KOT49H.
This release came hot on the heels of the 4.4.1 release, so don't expect much in the way of changes. This is a bugfix release - a touch up, not a makeover - and one that we have already detailed. Still, users will be happy to see it make an appearance in custom ROMs such as CyanogenMod, AOKP, and OmniROM in the days ahead.
