If the suggestion is to use ChangeLog data for this feature, then I
think it won't be easy, because it isn't easy to parse the ChangeLog
text for gleaning this more accurate information.  For starters, we
sometimes say "New function", sometimes just "New", and sometimes have
lists of functions (all of which are new) with a single "New" entry.

It would be better to have a DB of this data, which we would update
with each major release, than to try to parse ChangeLog files, IMO.
