DEP: Minimum supported Python version 3.10 #1357

Closed snowman2 closed 10 months ago

snowman2 commented 10 months ago

Python 3.9 is no longer supported in the scientific python ecosystem: https://scientific-python.org/specs/spec-0000/

Related #1111

Ah so pyproj follows scipy instead of numpy which doesn't drop 3.9 until April:

Ah sorry, numpy drops 3.8 in April if I'm reading that right.

The note at the top: "This NEP is superseded by the scientific python ecosystem coordination guideline SPEC 0 — Minimum Supported Versions."

Ubuntu LTS users (like me) will have only a few months to move to Ubuntu 24.04 (with python 3.12). That applies as well for PROJ docker image.

The dead snakes ppa is a great resource: https://launchpad.net/~deadsnakes/+archive/ubuntu/ppa. pyproj uses it to test pyproj on Ubuntu with newer versions of Python in GitHub actions.
