Make it < 3.14.
Things might break otherwise in future

+1 Python changes a lot between the minor versions :)

[ab93]

TBH, it is very difficult to support 5 versions of Python simultaneously and have trouble free builds. I would vote for dropping support for 3.9 if we are adding 3.13.
Anyway 3.9 is going obsolete after Oct 2025.

+1 yank support for 3.9

I'm against limiting the version of Python.
Please read the following: https://iscinumpy.dev/post/bound-version-constraints/
If you still think there's a good reason to block 3.14+, please share it.

Note that supported versions will still be listed in classifiers... so if somebody uses a version not listed, then they use at their own risk.

[khneal]

I'm ambivalent about dropping support for Python 3.9, so I'll refrain from giving an opinion on that.

[ab93]

Please make sure a minor version is released for this (when you release it).

[ab93]

Add "Programming Language :: Python :: 3.13"
in the classifiers

[ab93]

You also need to add tests to make sure python 3.13 pass

Per my other comment, please consider changing to:

Suggested change

	python = ">=3.9,<3.14"
	python = "^3.9"

Or if none of this packages dependencies cap the Python version (unlikely), then this would be better:

Suggested change

	python = ">=3.9,<3.14"
	python = ">=3.9"

@cosmic-chichu

1. Lets test the CI build workflow
2. proto compatibility
3. UDF e2e execution

[vigith]

2. proto compatibility

This is tricky, let's a CI rule for that in a follow up. I do not want to block this PR because of that.

[khneal]

Please consider removing the Python minor version cap, maybe in the next PR.

Is this PR still moving forward? I don't see any updates more than a month, and Python 3.13 went GA more than 6 months ago.
