Wheel file generated with maturin 1.7.6 doesn't check with twine 5.1.1

[konn]

Bug Description

With maturin 1.7.6, the wheel file generated by pip wheel won't be validated with twine check with twine >= 5.1.1.
The root cause seems that maturin 1.7.6 switched to metadata version to 2.4, which is not yet supported by twine 5.1.1 - so this might have to be addressed on twine side and it seems that there is the PR for this.

So,the reason I opened this issue is not to request fix this issue on maturin side- rather, I intend this issue to be a note for anyone else who encountered this situation. If this is inappropriate, please feel free to close this.

Your maturin version (maturin --version)

1.7.6

Your Python version (python -V)

3.9.20

Your pip version (pip -V)

pip 23.0.1

What bindings you're using

pyo3

Does cargo build work?

• Yes, it works

If on windows, have you checked that you aren't accidentally using unix path (those with the forward slash /)?

• Yes

Steps to Reproduce

1. Build PyO3 project with maturin 1.7.6
2. Bundle it with pip wheel
3. Feed it to twine@5.1.1 check, then it complains as follows:

Checking dist/my-package-cp39-cp39-macosx_11_0_arm64.whl: ERROR    InvalidDistribution: Metadata is missing required fields: Name, Version.
         Make sure the distribution includes the files where those fields are specified, and is using a supported Metadata-Version: 1.0, 1.1, 1.2, 2.0,
         2.1, 2.2, 2.3.

Yeah I don't think we'll fix it on maturin side, but I've pinned it to increase visibility.
