I would bump versions according to changes relative to the last released
GHC version, otherwise you have to increase the versions too often.
E.g. if directory-126.96.36.199 was released with latest GHC and I make a change
today that requires to bump to directory-1.2, and another change to the
API tomorrow, then the version should still be directory-1.2 and not
directory-1.3. That is, there are different packages with the same version
flying around but a release of GHC should finally fix the API that is
connected to a package version number.
