I dug around and found that it was just a bug fix. I already had 4.3. So far, I'm not sure if it helped or hurt more. My Video Player keeps showing as running above the threshhold (Addons Detector) even though I'm not opening it at all.
This morning, my battery drain after charging overnight was ridiculous. I dropped from 100 to 9% in about 2 hours. That's far from typical.
We'll see what else comes up...
