Release request (1.17.0)

[beagold]

I have recently tried to test compatibility with the upcoming CPython 3.13 version (at the time of writing: 3.13.0a5), but ran into some issues regarding cffi incompatibility, which seem to already have been fixed by #34.

Since it has been a while since a release has been made, I would like to request a new one to be made to, not only release this 3.13 fix, but also any improvements that have been made along the way.

Thanks!

I ran into a similar issue, where jupyterlab server fails when trying to store hashed passwords.

Thank you @beagold, now I fixed it by installing the latest cffi with:

python3 -m pip install git+https://github.com/python-cffi/cffi

Also great thanks to all of you! 🎉

I've usually held releases to support a Python pre-release until the new Python version hits at least beta 1, since the C APIs are often in heavy flux during the alpha period. This has been especially true for 3.13- basically every alpha release has had major breaking API changes that would have broken any released code targeting 3.13. While it's possible to tie those changes to individual pre-releases and continually release updates during the pre-release period, it's much more difficult to test against multiple pre-releases simultaneously and release things so frequently.

My current plan is still to do at least a CFFI pre-release around 3.13.0b1, with the expectation that future betas are likely to have breaking changes (though they're not supposed to)...

Thanks for the insight @nitzmahone!

I supposed that was the case, but I wanted to ask anyways.

I'll wait for beta to roll around to properly announce 3.13 support for our library. For now, I'll make some quick checks by previously pulling cffi from git.

Thanks again!!

Also waiting release for musl arm64 wheels #69

With the beta around now, I expect many people will enable Python 3.13 in their CIs, and then run into the _PyErr_WriteUnraisableMsg issue (e.g. because they use cryptography).

3.13.0b1 will also soon be available to setup-python: actions/python-versions#272

[nitzmahone]

CFFI 1.17.0rc1 has been tagged and released to PyPI. The final release will likely coincide with Python 3.13.0rc1 around July 30.
