Log Message:
py-greenlet: update to 3.0.1.

Switch to wheel.mk.

3.0.1 (2023-10-25)
==================

- Fix a potential crash on Python 3.8 at interpreter shutdown time.
  This was a regression from earlier 3.0.x releases. Reported by Matt
  Wozniski in `issue 376 \ 
<https://github.com/python-greenlet/greenlet/issues/376>`_.

3.0.0 (2023-10-02)
==================

- No changes from 3.0rc3 aside from the version number.

3.0.0rc3 (2023-09-12)
=====================

- Fix an intermittent error during process termination on some
  platforms (GCC/Linux/libstdc++).

3.0.0rc2 (2023-09-09)
=====================

- Fix some potential bugs (assertion failures and memory leaks) in
  previously-untested error handling code. In some cases, this means
  that the process will execute a controlled ``abort()`` after severe
  trouble when previously the process might have continued for some
  time with a corrupt state. It is unlikely those errors occurred in
  practice.
- Fix some assertion errors and potential bugs with re-entrant
  switches.
- Fix a potential crash when certain compilers compile greenlet with
  high levels of optimization. The symptom would be that switching to
  a greenlet for the first time immediately crashes.
- Fix a potential crash when the callable object passed to the
  greenlet constructor (or set as the ``greenlet.run`` attribute) has
  a destructor attached to it that switches. Typically, triggering
  this issue would require an unlikely subclass of
  ``greenlet.greenlet``.
- Python 3.11+: Fix rare switching errors that could occur when a
  garbage collection was triggered during the middle of a switch, and
  Python-level code in ``__del__`` or weakref callbacks switched to a
  different greenlet and ultimately switched back to the original
  greenlet. This often manifested as a ``SystemError``: "switch
  returned NULL without an exception set."

For context on the fixes, see `gevent issue #1985
<https://github.com/gevent/gevent/issues/1985>`_.

3.0.0rc1 (2023-09-01)
=====================

- Windows wheels are linked statically to the C runtime in an effort
  to prevent import errors on systems without the correct C runtime
  installed. It's not clear if this will make the situation better or
  worse, so please share your experiences in `issue 346
  <https://github.com/python-greenlet/greenlet/issues/346>`_.

  Note that this only applies to the binary wheels found on PyPI.
  Building greenlet from source defaults to the shared library. Set
  the environment variable ``GREENLET_STATIC_RUNTIME=1`` at build time
  to change that.
- Build binary wheels for Python 3.12 on macOS.
- Fix compiling greenlet on a debug build of CPython 3.12. There is
  `one known issue
  <https://github.com/python-greenlet/greenlet/issues/368>`_ that
  leads to an interpreter crash on debug builds.
- Python 3.12: Fix walking the frame stack of suspended greenlets.
  Previously accessing ``glet.gr_frame.f_back`` would crash due to
  `changes in CPython's undocumented internal frame handling \ 
<https://github.com/python/cpython/commit/1e197e63e21f77b102ff2601a549dda4b6439455>`_.

Platforms
---------
- Now, greenlet *may* compile and work on Windows ARM64 using
  llvm-mingw, but this is untested and unsupported. See `PR
  <https://github.com/python-greenlet/greenlet/pull/224>`_ by Adrian
  Vladu.
- Now, greenlet *may* compile and work on LoongArch64 Linux systems,
  but this is untested and unsupported. See `PR 257
  <https://github.com/python-greenlet/greenlet/pull/257/files>`_ by merore.

Known Issues
------------

- There may be (very) subtle issues with tracing on Python 3.12, which
  has redesigned the entire tracing infrastructure.

3.0.0a1 (2023-06-21)
====================

- Build binary wheels for S390x Linux. See `PR 358
  <https://github.com/python-greenlet/greenlet/pull/358>`_ from Steven
  Silvester.
- Fix a rare crash on shutdown seen in uWSGI deployments. See `issue
  330 <https://github.com/python-greenlet/greenlet/issues/330>`_ and `PR 356
  <https://github.com/python-greenlet/greenlet/pull/356>`_ from Andrew
  Wason.
- Make the platform-specific low-level C/assembly snippets stop using
  the ``register`` storage class. Newer versions of standards remove
  this storage class, and it has been generally ignored by many
  compilers for some time. See `PR 347
  <https://github.com/python-greenlet/greenlet/pull/347>`_ from Khem
  Raj.
- Add initial support for Python 3.12. See `issue
  <https://github.com/python-greenlet/greenlet/issues/323>`_ and `PR
  <https://github.com/python-greenlet/greenlet/pull/327>`_; thanks go
  to (at least) Michael Droettboom, Andreas Motl, Thomas A Caswell,
  raphaelauv, Hugo van Kemenade, Mark Shannon, and Petr Viktorin.
- Remove support for end-of-life Python versions, including Python
  2.7, Python 3.5 and Python 3.6.
- Require a compiler that supports ``noinline`` directives. See
  `issue 271
  <https://github.com/python-greenlet/greenlet/issues/266>`_.
- Require a compiler that supports C++11.
