Just adding that Ubuntu 23.04 (lunar) shipped with py3.11 and 2023.1 (antelope) packages, and the UCA for 2023.1 on Ubuntu 22.04 (jammy) was py3.10, so 2023/1/antelope is tested on both.  Mantic (Ubuntu 23.10) looks like it will be py3.11 again, so bobcat will be on both py3.10 and py3.11, and for 24.04 (the next LTS) may well be py3.12.

So, like Thomas, we're usually a python or 2 ahead of the 'official' supported version upstream; i.e. at this point, pretty much everything that's packaged in Debian and Ubuntu at least module imports without failures on py3.11; and 'probably' works from a tempest perspective.  But obviously, we don't test everything to the depth that upstream does, so perhaps that point is a bit moot.

A thought did occur to me though: as container based/docker/k8s solutions to the control plane are becoming more used, it's likely that the official python test might be the important data point as the container build would (from a risk perspective) more likely select the official supported python version; the host's python that the containers are run on becomes largely irrelevant.  In this situation, upstream "next python version" testing becomes all the more important.

Thanks Zigo for you testing and effort, that is really appreciated.

I like the idea of testing the 3.12 in advance even with RC release. Also, as you mentioned
we will be testing it in advance as non voting so doing it on Debian experimental version
is not bad idea. this will give projects more time to fix the issues. And once we have stable
version of distro having v3.12 then we can switch the job to that distro.

I think ubuntu also going to package it in ~Nov/Dec time so that also one option
to add it as non voting.
