I announced that, for now, The Zope head won't work with old databases. We are going to have to come up with some code to deal with the old btrees and intsets.
The good news is that, databases created with Zope 2.7 final should work. :)

Just tried. Seems to have fixed it. Now, for the next step *wink*.
If I try starting Zope with an old existing database I get the traceback below. Correct me if I'm wrong, but I think the error with 'UserDict' has nothing to do with the 'Could not import class 'BTree'' or am I wrong?
I think the attribute error on data is just a symptom of the BTree failure. The object has no data attribute, because ZODB failed to unpickle the object that would be assigned to data.
I don't know what happened with backwards compatibility for the old BTree classes. When Jim and I discussed it a while back, I thought we concluded that we would provide a script that would convert all the old BTree instances to new BTrees instance. But I don't know if that decision stuck or if the script was ever written.
