All supported operating systems ship with python 3.10 (or later), so bumping the minimum should not cause any issues. A bump will allow new code to use new python features.

For reference:
- https://packages.debian.org/bookworm/python3
- https://packages.ubuntu.com/jammy/python3
- FreeBSD 13/14 ships with 3.11
- CentOS-like 8/9 ships with 3.11/3.12 (via appstream)
- OpenSuse Tumbleweed ships with all python versions, e.g. https://software.opensuse.org/package/python312-base
This is for Bitcoin Core 29.0 in 2025 (next year), not the soon upcoming 28.0 this fall.

I agree on using newer tools.

A bump will allow new code to use new python features.

Out of curiosity, which features can you mention specifically?
maflcko commented at 10:34 AM on August 29, 2024: member

In theory one could use the Python match, which was ported from Rust, IIRC.

Not sure if anyone wants to do that, or if it is worth it. Happy to close this pull instead and do a bump to 3.11 next year instead, which comes with more useful features.

- Fedora 40 ships 3.12.5
- Alpine v3.20 ships 3.12.3
- Arch ships 3.12.5

In that case, it might be worth just waiting to bump to 3.11 instead.

Note: focal is supported until April 2025 and ships with 3.8, but since that's already unsupported as per our current 3.9 requirements that doesn't really change anything.
