I was on stock, rooted 5.9.902 and was just prompted to Download and Install 5.9.905 OTA. I backed up root with Voodoo OTA Root Keeper, temp unrooted, downloaded and installed 5.9.905, let the phone reboot, then restored root using Voodoo OTA Root Keeper. All went smooth and am now on the official OTA with root. I noticed the addition of Google+ as a preinstalled app. I am assuming, however, that there is no difference between the 5.9.905 that was pulled from Motorola's servers a few weeks back.
