Dear Lisp hackers,
ASDF 3.0.0 was decidedly short-lived. Longer live ASDF 3.0.1!
An undocumented feature of version-satisfies, since the early days of ASDF 1, was that it would reject a component that didn't exactly match the specified major version as well as otherwise be same or newer as specified version. Of course, this broke quicklisp's check for a newer ASDF when ASDF went from major version 2 to major version 3. Since the feature was undocumented, and that users don't seem to ask for it, whereas many power users are inconvenienced by it, I just removed it.
A future maintainer of ASDF may extend the `(:version ,dependency ,minimum-version) pattern for specifying dependencies with a `(:version ,dependency ,minimum-version ,too-large-version) pattern that allows to specify an exclusive upper bound on compatible versions. This would allow finer specification of compatible version ranges than just a match on the major version. But I didn't implement it. I leave it as an exercise for whoever volunteers to replace me, since I'm definitely leaving active maintenance of ASDF and unwilling to implement new features, though I will still fix bugs until a new maintainer rises.
PS: this fiasco also suggests that a new maintainer shall include some typical quicklisp usage as part of the automated test suite.
