Bug report

Bug description:

Inobject.h, I believe

#define Py_RETURN_NOTIMPLEMENTED return Py_NOTIMPLEMENTED

should be

#if defined(Py_LIMITED_API) && Py_LIMITED_API+0 < 0x030c0000#  define Py_RETURN_NOTIMPLEMENTED return Py_NewRef(Py_NOTIMPLEMENTED)#else#  define Py_RETURN_NOTIMPLEMENTED return Py_NOTIMPLEMENTED

andPy_NotImplemented should addChanged in version 3.12: Py_NOTIMPLEMENTED is immortal.

andPy_RETURN_NOTIMPLEMENTED should sayReturn Py_NotImplemented from a function. without saying it creates a new strong reference.

CPython versions tested on:

3.14

Operating systems tested on:
