Another problem: If a backport were made to a minor release series, like so,
a.b.0 2024-07-01
a.c.0 2024-07-02
a.b.1 2024-07-03
then the above would produce the wrong order.
So sorting just by version might be better after all, we'd just need to resolve the v3 RC/alpha situation somehow:
[3.0.0-RC1/] 2021-04-01 21:18
[3.0.0-alpha2/] 2021-09-11 11:54
[3.0.0-alpha3/] 2022-06-17 12:27
Updated the code yet again. This time by inheriting from packaging's Version class and hooking date into the compare key.
While that addresses the above issue, it might be a bit wonky, because technically that's private API...

I updated the code above; should work now.
