Support for Python beta releases (3.13)?

[kpfleming]

I'd like to start using these builds (via Hatch), but I test my software against Python beta releases too. Would it be reasonable to add 3.13 beta releases to the set of builds in this repository?

[zanieb]

Yes probably but it's non-trivial. Are you interested in working on it?

[kpfleming]

Absolutely. If you know of traps for the unwary, I'm happy to tackle them :-)

[zanieb]

I'm still new to the project :) but this was on my list of things to do eventually so feel free to ping me with any questions and we can work through it together.

For some more context, I added #236 in preparation for support for building CPython from GitHub. I was going to get that working on 3.12 before moving to 3.13 / latest so we can continually test against the latest CPython. I presume there are official sources for the 3.13 beta around though so we don't need to go that route.

[kpfleming]

Right, there are tarballs for the beta releases so building them should be very similar to building the other ones. I'll give it a try, starting with 3.12 as the baseline.

[kpfleming]

I've created #264 which is an optimistic PR assuming that Python 3.13 will build using exactly the same process as 3.12. It will require someone with maintainer privileges to approve the workflows since this is my first contribution to this repository :-)

[zanieb]

For others, there's work in progress on this at #264 (Thanks Kevin!)

It would generally be awesome to have builds for alpha/beta/rc releases of new minor Python versions (currently 3.13, for example). But I understand that this potentially represents a ton of work, making it hard to stay up to date with all the pre-releases before the final one 🙂 So, just wishful thinking! Thanks to all the contributors of this project, it's really helpful ❤️

was this resolved in?

• Support for Python 3.13 #319

[zanieb]

Yes, but they're not released yet. I'll close once we publish a release with 3.13rc2.

Hi @zanieb,

Any estimate as to when support might be added here? Thanks!

[zanieb]

We released 3.13rc2 and 3.13rc3 already!

[sydney-runkle]

@zanieb,

Awesome!

Perhaps I'm missing something obvious - when I run rye pin 3.13rc3, I get the following:

error: unsupported/unknown version for this platform

I thought perhaps that was blocked by this issue, but maybe they're not connected.

Any recommendations here? Thanks for your help!

[kpfleming]

That's a rye issue...

[zanieb]

Sounds like the downloads just haven't been updated in Rye yet. It was non-trivial to add support for pre-releases in uv, but they're available there.

[sydney-runkle]

It was non-trivial to add support for pre-releases in uv, but they're available there.

Awesome, thanks! Will use uv then. Apologies for my misplaced question here.
