Nice contribution! What's still needed for Python 3.14?

I am not certain. Some of the pending issues are tracked on the main Fedora 43 issue. Like this one.

[reneleonhardt]

Thank you! So is there something missing to undraft and review this? 🙂

Actually this is also ready for review. The only issue is lack of time. More information here.

This PR is for dom0, and there are no plans to change Python version in R4.3 dom0 (it will stay at 3.13). This PR may be useful only for the future (R4.4 and beyond).

[reneleonhardt]

What does may be useful mean? It may not be needed for R4.3 but it modernizes docs, tools, tests and vm while still working on 3.13 (Fedora 41 and 42) and allowing CI to prepare in time for the next Fedora ❤️

[marmarek]

Yes, but at this time "main" branch is open only for changes that are necessary for R4.3.

[reneleonhardt]

I couldn't find this information in the README, only the master branch is being mentioned there. Maybe you want to make the documentation clearer or introduce a v4.4 integration branch for future features.

See https://doc.qubes-os.org/en/latest/developer/releases/version-scheme.html#release-schedule Anyway, this is not the place for such discussion.
