Hmm, I don't like that, it'll just make things look old :-) For now
I've applied a patch to update the values with what it is now.
Perhaps we should just add it to the release checklist to verify that
they are reasonably correct? Shouldn't take too long, and it's not
likely it'll ever change in a minor release - only major releases are
interesting.
