Re: [Distutils] PEP440: foo-X.Y.Z does not satisfy "foo>X.Y"?

This makes sense if you view "1.7" as encompassing all of the releases

1.7.0, 1.7.1, 1.7.2, etc. (and their variants). It's a bit like the "significant digits" of a number. [1] You want the release to be bigger than all releases of that type.

but is this really the underlying concept? Does the PEP explain this as a justification? Where?
