Log Message:
py-gevent: updated to 23.7.0

23.7.0 (2023-07-11)
===================

Features
--------

- Add preliminary support for Python 3.12, using greenlet 3.0a1. This
  is somewhat tricky to build from source at this time, and there is
  one known issue: On Python 3.12b3, dumping tracebacks of greenlets
  is not available.
  :issue:`1969`.
- Update the bundled c-ares version to 1.19.1.
  See :issue:`1947`.

Bugfixes
--------

- Fix an edge case connecting a non-blocking ``SSLSocket`` that could result
  in an AttributeError. In a change to match the standard library,
  calling ``sock.connect_ex()`` on a subclass of ``socket`` no longer
  calls the subclass's ``connect`` method.

  Initial fix by Priyankar Jain.
  See :issue:`1932`.
- Make gevent's ``FileObjectThread`` (mostly used on Windows) implement
  ``readinto`` cooperatively. PR by Kirill Smelkov.
  See :issue:`1948`.
- Work around an ``AttributeError`` during cyclic garbage collection
  when Python finalizers (``__del__`` and the like) attempt to use
  gevent APIs. This is not a recommended practice, and it is unclear if
  catching this ``AttributeError`` will fix any problems or just shift
  them. (If we could determine the root situation that results in this
  cycle, we might be able to solve it.)
  See :issue:`1961`.

Deprecations and Removals
-------------------------

- Remove support for obsolete Python versions. This is everything prior
  to 3.8.

  Related changes include:

  - Stop using ``pkg_resources`` to find entry points (plugins).
    Instead, use ``importlib.metadata``.
  - Honor ``sys.unraisablehook`` when a callback function produces an
    exception, and handling the exception in the hub *also* produces an
    exception. In older versions, these would be simply printed.
  - ``setup.py`` no longer includes the ``setup_requires`` keyword.
    Installation with a tool that understands ``pyproject.toml`` is
    recommended.
  - The bundled tblib has been updated to version 2.0.
