The latest version of the Play Store is no longer 3.7.11 - say hello to v3.7.13. I haven't found anything different from 3.7.11 just yet - it likely only contains bug fixes. There's no reason to lag behind, however, so if you're running a Play Store with a version lower than 3.7.13, jump right to the download mirrors below. Before you do that, let me point out a few things.
Upon playing with the Store further, I did discover a new feature compared to v3.5.19 that I didn't mention last time - inline app links in search suggestions.

After upgrading my Galaxy Nexus (GSM) to Jelly Bean last night (I know, I know, I'm a few days late), I unlocked its bootloader (the usual fastboot oem unlock) and commenced rooting, which I thought would only take a minute or two. However, after almost 2 hours of pushing, flashing, rebooting, and trying no less than 5 different root methods, I still didn't have root. Something must have changed under the hood, and no root method I was trying was working (even PaulOBrien's SuperBoot).
