I just noticed through random chance that there was a new release
back in January: https://metacpan.org/release/OpenGuides
I mention in case anyone is interested.
It's been a very long time since I even thought about OpenGuides,
I'm afraid. But since for the first time since I can remember
I got emailed by london.openguides.org (with a user who was
mainly trying ot leave a message about how out of date everything
is). And according to my email archives it's being in "wind down"
state for about a decade... I think it accidentally regained editability
after a sever migration a few years ago.
Neither cambridge, london or oxford are being actively used or
maintained by anyone, as far as I know, for many years, so it's
probably time I (not-so?)-gracefully turn them all off.
