Ok, I added another operation "changelog", that gives you four-tuples
name, version, timestamp, action. It's the complete journal, except
that privacy fields (author and IP) are not returned, and except
changes to the package (rather than a specific release) are not
returned.

The possible values for "action" remain undocumented. If there is
interested, people can propose a specification that PyPI should
try to stick to; this specification should allow for
still-undocumented action values (to allow addition of more actions).
