* C extensions built with the :ref:`limited C API <limited-c-api>`
on :ref:`Python build in debug mode <debug-build>` no longer support Python
3.9 and older. In this configuration, :c:func:`Py_INCREF` and
:c:func:`Py_DECREF` are now always implemented as opaque function calls,
but the called functions were added to Python 3.10. Build C extensions
with a release build of Python or with Python 3.12 and older, to keep support
for Python 3.9 and older.
