Hi all,
The upgrade was unusually painless, so I went ahead and added the blogging feature too, which was also pretty painless.
I don't actually know what the upgrade entails, but I have noticed so far that member profiles are a whole lot more interesting, and have taken on a more social network feel.
You will notice a new link in the navbar for the blogs. I haven't even had time to explore this feature at all, so all I can say is have a play and see what you think.
Enjoy!
