Consider releasing a new greenlet 1.1.3 version compatible with Python 3.11

[vstinner]

The current main branch is a new greenlet 2.0 version which has a different API than greenlet 1.x and is written in C++. Shipping greenlet 2.0 alpha in the future Fedora 37 scheduled for next October (2022) sounds risky. We (Fedora) would like to upgrade Python to Python 3.11 but keep greenlet 1.x.

Would you be open to consider releasing a new greenlet 1.1.3 version which would be compatible with Python 3.11?

We prepared a PR on top on the 1.1.2 version to add Python 3.11 support.

Python 3.11 final version is also scheduled next October (2022): https://peps.python.org/pep-0664/#schedule

We wrote the PR #306 which adds Python 3.11 support to greenlet 1.x.

@jamadden: What do you think of this issue?

It seems like @ssbarnea also wants a greenlet compatible with Python 3.11: #306 (comment)

Would be great to get a release out, as there's been some stability issues with Python 3.11 beta so it's very important to test it, and this is blocking other projects testing 3.11 that depend on greenlet.

Thank you!

Python 3.11 rc1 will be released on August 8th. It would be great if we can have the Python 3.11 support at the same time.

Would really appreciate a fix here; pynvim is dependent on greenlet, and so many nvim configurations are now broken when using Python 3.11.

Exactly. I just switched to nvim-cmp from coq_nvim for this reason yesterday.

#306 has been merged and 1.1.3 released to PyPI.
