I'll be posting a 7.2 based BottomFeeder soon. The only real change so far is componentization - I've split a number of the non-Bf specific components out of the BottomFeeder parcel, so that they can be independently updated. The version information available in the "about" box is also going to be a little cleaner.
This will all be done in a new directory structure - moving will require a new base image - and the new parcel structure isn't completely compatible with what's deployed right now. When I get it all on the server, I'll post an update
