I did the upgrade today. Only took about an hour (including making the backups). Only glitch was that I needed to modify the permissions on the new Groups folder. Had to guess what user to modify and how much to change, but I got it right on the first try.
I'm looking but can't find ANY changes that an end-user would be interested in. Has the past 11 months only delivered bug fixes?!?!?
Is the "Top Posters" island available in this package?
