they are confirmed to be linked to a bug in lockscreen widgets, dev as well as google seem to be aware of that and working on it

Does this update fix the bluetooth issues (stuttering, poor voice quality and random disconnects)?

I am just about to return my Nexus 4 because I nees functional bluetooth and I may as well hold fire if a fix is on the way.
1.1 mb? No way. An update that small can only be a few lines of code - i.e. adding back in December.

Nothing special here. Just adding back in December I'd bet. I'm all about getting excited for an OTA, but to go through the trouble to flash this is crazy. Unless you were born in December!

Random reboots and battery drain are usually linked to misbehaving apps. Pressure the dev to fix their stuff.
Sometimes, but in theory an app should never be able to bring down the entire OS. As a previous Nexus owner, my experience has been that the random reboots (OS crashes) are fairly typical on the new Nexus devices. Usually by spring or summer, Google has them all worked out.

Actually tens of thousands of lines of code can be contained within 1 MB. My Windows Phone app, MetrofaceLIFT, has over 1000 lines of code and is only about 200 KB. The files contained within the update are diff files, meaning they contain only the bits of each file that changed. Unzip the update yourself and you'll see that hundreds of files are changed in this update. Some changes are just version bumps, sure, but others likely contain more code than you think. From analyzing the update, I guarantee there are bluetooth and nfc fixes, camera tweaks, and sensor tweaks. You may not notice them in day to day use, but they're there. Hell, one guy in this thread already said this update fixed compatibility with his NFC tags.

Just updated to 4.2.1 using the file from post #3. Used Voodoo's OTA Rootkeeper to preserve root and everything worked fine. Used TWRP to install that zip file.

I can confirm that this method works. I preserved root, updated, and restored root using Voodoo's OTA Rootkeeper.

Thanks for the tip!

Just read on MobileSyrup that it will take a couple days for all the updates to roll out to people. Maybe they are doing it by region?
Generally Google just randomly rolls it out. Rarely is it done by region unless there are radio changes and Google finds issues with certain carriers (no radio changes in this build).

After flashing through CWM, it notified me that root had been broken and asked if I wanted to repair it. I said no because I already backed up root in RootKeeper. Would it have worked if I pressed yes?

Sorry but there are definitely NFC and sensor changes in this release. Since they are patch files, it takes very little space when the changes are only bug fixes.

It did for me.
To clarify, after flashing the new OTA update through CWM, CWM notified you that root had broken and asked whether you wanted to restore it. You said yes, and it worked?

Sorry for the bluntness, I want to make sure we're on the same page here.

If you say yes, you will not lose root.
