Feature Request

Hi team!

Python 3.10 will be released next Mon, Oct 4, but at a moment it is still impossible to release a package to PyPI via stable poetry (1.1.10) && poetry-core (1.0.6), which will include "Programming Language :: Python :: 3.10" trove classifier, as AVAILABLE_PYTHONS list still does not contain "3.10" version.

In same time, poetry-core@master already has included "3.10" to list of AVAILABLE_PYTHONS, so I am wondering is there any chance to backport this change and include "3.10" classifier, when building package via stable poetry && poetry-core at Python 3.10rc2.

I understand, that I can manually include "Programming Language :: Python :: 3.10" classifier to list of classifiers in pyproject.toml, but I find that fix not very intuitive and clean.

Thanks in advance and let me know, if I can provide any additional info on a topic.

• Running poetry build at Python 3.10.0rc2
• Released PyPI version without Python 3.10 classifier

poetry-core==1.0.7 released with fix for this issue: python-poetry/poetry-core#215

Now, it is possible to reinstall poetry if you're using pipx via,

pipx reinstall poetry

and it will automatically add Programming Language :: Python :: 3.10 as classifier to the package.

Thanks a lot!

ps. Not sure, whether new poetry release, which will require poetry-core>=1.0.7, is planned or not, so leaving this issue as open. But if you come here from search, reinstalling poetry should fix the issue for you.

And now it is for sure fixed via poetry==1.1.11 release.

Thanks again!
