I remember the one bug being a spacing issue that only showed up with
very specific documents, the other bug I accidentally introduced while
fixing a different bug (oops). Both bugs were fixed before TL25 was
released (or maybe it was shortly after?), so MkII should be fine.

Most of the font authors are pretty careful to not change the metrics in
updates, so that's not usually a big deal. But hyphenation patterns
definitely change, so most users who care about identical page breaks
will just use a frozen (and usually ancient) version of TeX Live and
never upgrade.

Ok, sounds good to me. Let me know if/when you want me to change
anything.

If you run "tlmgr paper a4" the file will contain
\setuppapersize[A4][A4]
which is probably not worth warning over.
