* Fix an intermittent error during process termination on some
platforms (GCC/Linux/libstdc++).
* 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."
* 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
* Make the platform-specific low-level C/assembly snippets stop using
the ``register`` storage class. Newer versions of standards remove
