I apologise if I misunderstood the BBB implications of your zope.file
work: I thought I understood that existing apps might need changes to
keep the menu registrations active.

It *is* a maintenance branch (the branch from which 0.6.x releases really
ought to be made). The fact that the trunk had not (yet) diverged was
merely a happy accident.

I disagreed with the "just release from the trunk" choice earlier, but
went along with it: we kept having cases where feature work on the trunk
would break tests in the "released" ZTK dev buildouts. As the number of
incompatible trunks grew (e.g., dropping compatiblitiy tieh Ptyhon 2.4 /
2.5), it finally became too big a drag on that development to have the
"released" ZTK dev tests using trunks.

We should *not* be looking for the ZTK 1.0 / 1.1 dev buildouts to tell us
that we have "broken" something on a trunk: new versions of ZTK 1.0.x /
1.1.x should be *very* conservative, accepting only true bugfix updates
to their packages.

Again, I apologise for my misunderstanding. If you are confident that
existing apps won't need any changes when upgrading to 0.6.2, then we
shouldn't need to shuffle the releases.
