Beginning Flask v2.3.0, the support for Python 3.7 is dropped. So we have pinned to the last version of 2.2.*.
We cannot stay there, and we'll need to update this. Most of the python packages are dropping support for python 3.7.
So should we move ahead or stay put? I can see most OS's have at least python 3.8 packages.
Most? What platforms do we support that don't have 3.8+?
From what we support, only Debian 10(Buster)do not have a 3.8+ python release.
Hmm, well Buster has just moved into LTS, where it'll be for about another year. I'm on the fence about whether we should de-support it now; it's still in common use AFAIA - in fact postgresql.org still has a handful of installations that have yet to be moved to Bullseye.
