deprecate python 3.9 (#10390)

mirror of https://github.com/certbot/certbot.git synced 2026-08-02 00:22:28 +02:00

i based this PR on https://github.com/certbot/certbot/pull/10034/

this is maybe a little early since [python 3.9's EOL is in
october](https://devguide.python.org/versions/#supported-versions), but
i thought this would be good to do now to ensure we didn't forget, help
keep us on schedule when we're not releasing every month, allow us to
fix the security alert those with access can see at
https://github.com/certbot/certbot/security/dependabot which is caused
by [us (transitively) needing an old version of urllib3 with python
3.9](https://github.com/certbot/certbot/blob/d80b1d395a146ceef361664640f97c6db2ae47de/tools/requirements.txt#L195),
and simplify development ever so slightly as discussed at
https://github.com/certbot/certbot/pull/10179

i created https://github.com/certbot/certbot/issues/10389 to track
dropping support entirely
