Python versions support #7935
Description
After discussions in #6613 and #7886, here's my proposed way forward
| CKAN version | Minimum Python version supported | Actions needed |
|---|---|---|
| 2.10 | 3.7 | In the dev-v2.10 branch, add modifiers to requirements.in for backports-zoneinfo==0.2.1; python_version < '3.9' and greenlet==2.0.2 ; python_version > '3.10' to allow install on Python 3.10 |
| 2.11 | 3.9 | Make the tests and other runners run on Python 3.9, compile requirements.txt using Python 3.9. Update setup.cfg and docs |
| 2.12 | 3.10 | Update setup.cfg and docs after 2.11 is branched. |
This makes sense to me looking at Python's support schedule and is inline with what other similar projects are doing:
| Project | Python versions supported on latest release | Python versions supported in development branch |
|---|---|---|
| GeoNode | >= 3.7 (4.1.3) | >= 3.10 (master) |
| Django | >= 3.8 (4.2.7) | >= 3.10 (master) |
