Bumps cython from 0.29.36 to 3.0.0.

Changelog

Sourced from cython's changelog.

3.0.0 unified release notes

Cython 3.0.0 has been a very large effort that cleaned up many old warts, introduced many new features, and introduces a couple of intentional behaviour changes, even though the goal remained to stay compatible as much as possible with Cython 0.29.x. For details, see the migration guide_.

.. _migration guide: https://cython.readthedocs.io/en/latest/src/userguide/migrating_to_cy30.html

As the development was spread out over several years, a lot of things have happened in the meantime. Many crucial bugfixes and some features were backported to 0.29.x and are not strictly speaking "new" in Cython 3.0.0.

Major themes in 3.0.0

Compatibility with Python

Since Cython 3.0.0 started development, CPython 3.8-3.11 were released. All these are supported in Cython, including experimental support for the in-development CPython 3.12. On the other end of the spectrum, support for Python 2.6 was dropped.

Cython interacts very closely with the C-API of Python, which is where most of the adaptation work happens. Independently, Cython strives to be able to parse newer Python constructs for use with its pure python_ mode, which has been a focus. In short, this allows to compile a wider range of Python code into optimized C code.
