Yep it's a fair point.

Some packages have a changelog file in them that we could display,
though most don't. For those that do have a changelog, how we avoid
displaying all of history is a bit tricky. For those that do not,
ideally we could derive a changelog by looking at the difference in the
API. The latter requires a tool we've not written yet.
