The upgrade script replaces the following call to PyObject_Del() with PyObject_Free() here: https://github.com/pygobject/pycairo/blob/ce6118526606f93d3132f881bf548ce746b782fe/cairo/path.c#L242 and it seems deliberate (??)

PyObject_Del() is documented to be used for PyObject_New() or PyObject_NewVar(), while PyObject_Free() is documented to be used for PyObject_Malloc(), PyObject_Realloc() or PyObject_Calloc(), otherwise it is undefined behavior.

• https://docs.python.org/3.14/c-api/memory.html#c.PyObject_Free
• https://docs.python.org/3.14/c-api/allocation.html#c.PyObject_Del

I'm a bit confused by this.
