It really would be nice if there was a place where users could
look this information up in the documentation (perhaps there is one
and I just cannot find it ;-)).

I don't really think that intro(4) is the right place for it,
either, though, but I don't see a better one. Thoughts?

Barring that, though, it seems to me that it should
definitely be in doc/CHANGES (and so should rev 1.35 bumping it to 1G),
and possibly even in the release notes.

Would you be willing to draft some text?

Thanks.
