The Google Nexus 7 tablet isn't quite available to the general public yet, but our Google I/O edition's just gotten an update. As you can see from the screen above, the 12.6MB update to Android 4.1.1 -- which just hit the AOSP servers yesterday -- "improves performance and responsiveness system wide." It also goes on to pimp out some of the newer features of Jelly Bean, including Google Now and the new notifications.
If you've already rooted your Nexus 7, this update will flash so long as you have stock recovery. OTA Rootkeeper works as it should, too, so you'll have no issues getting root access back. (Not that we ever though you would -- this is a Nexus after all.)
It also looks like local search is still enabled, which Jerry just finished explaining means we likely will see an update to Google's proprietary apps to get around that pesky Apple patent thing.
Also of note is that if you haven't installed Google Wallet before, it'll be there now. If there ever was a doubt Google was going to stick with its mobile payment solution, put it out of your mind.
