The problem is what constitues a "change in API"; as long as we
preserve what's documented,
that can be in the eye of the beholder, and we failed to document much.
That said, I agree there should probably be a #+asdf2.27 or something,
since I'm introducing some several major changes:
asdf-bundle, building those who depend-on a modified system, proper timestamps,
yet another complete rewrite of traverse, removal of :feature and

I don't think that will work any the better than now. You will still
have to look at the debian/changelog or git log to see when a feature
was introduced or removed.

If you care to specify the proper version of asdf to depend on,
the release-to-release debian/changelog and the commit-to-commit git
log are here to help.
