When PyPI was created there was a design discussion and decision made
that the site implement the most common case which is that package
authors expose only one version, the most recent one. Unsupported
versions are deliberately difficult to find. That's the point. The
intention is to reduce the authors' maintenance burden by discouraging
people from using older versions of their software.

Your example project, Sphinx, advertises precisely one current
version, 1.1.2. This is the one on their website and it's the one on

Some packages expose more versions because they have multiple release
branches and that's their choice. More versions are findable on the
site for those packages.

And, as has been pointed out, for data mining applications you can get
access to the full data.
