Earlier today, both the Nexus 4 and the Nexus 10 started receiving small ~1MB OTAs to Android 4.2.1 with fixes to the missing month of December in the People app, among other things. The corresponding open source files are being pushed by Google to the Android Open Source Project (AOSP) as we speak, Android release engineer Jean-Baptiste Queru just announced in the Android Building group.
The build number is JOP40D and the tag is android-4.2.1_r1. From what I can tell, a lot of the code is already up - here are some links to get you started:
The source code for 4.2.1 is being pushed into AOSP right now.

We all love Android, and we also love when Google releases a new iteration of our favorite mobile OS. Sometimes, though, even Google screws up a bit, and Android 4.2 is looking to be one of the most bug-ridden releases since Honeycomb. And, let's be honest: 4.2 isn't exactly the leap that 2.3 to 3.0 was, either. Chances are, if you're on Android 4.2, you've experienced at least one of the issues here. Some aren't that bad, but some can just ruin your day, and we're a little shocked Google missed them.
We'd love it if you could confirm whether these bugs happen on a device not listed as "known affected," or of any other serious issues you've been experiencing since the bump to 4.2 on your Nexus.
