I got it a few days ago. Not sure what it did, but my battery life (which was always good) seems to have gotten even better. That's the only change I've noticed.

I got the update this evening. So far, I've noticed that universal search is gone and my phone's screen doesn't turn off anymore when it's being charged. I didn't have this issue before the update.
