Pending removal in Python 3.20
******************************

* "_PyObject_CallMethodId()", "_PyObject_GetAttrId()" and
  "_PyUnicode_FromId()" are deprecated since 3.15 and will be removed
  in 3.20. Instead, use "PyUnicode_InternFromString()" and cache the
  result in the module state, then call "PyObject_CallMethod()" or
  "PyObject_GetAttr()". (Contributed by Victor Stinner in gh-141049.)

* The "cval" field in "PyComplexObject" (gh-128813). Use
  "PyComplex_AsCComplex()" and "PyComplex_FromCComplex()" to convert a
  Python complex number to/from the C "Py_complex" representation.

* Macros "Py_MATH_PIl" and "Py_MATH_El".
