To get a custom code object: create a code object using the compiler,
then get a modified version with the ``replace`` method.
* :c:type:`PyCodeObject` no longer has a ``co_code`` field. Instead,
use ``PyObject_GetAttrString(code_object, "co_code")`` or
:c:func:`PyCode_GetCode` to get the underlying bytes object.
(Contributed by Brandt Bucher in :issue:`46841` and Ken Jin in :gh:`92154`.)
* :c:type:`PyCodeObject` no longer has the ``co_code``, ``co_varnames``,
``co_cellvars`` and ``co_freevars`` fields. Instead, use
:c:func:`PyCode_GetCode`, :c:func:`PyCode_GetVarnames`,
:c:func:`PyCode_GetCellvars` and :c:func:`PyCode_GetFreevars` respectively
to access them via the C API.
(Contributed by Brandt Bucher in :issue:`46841` and Ken Jin in :gh:`92154`
and :gh:`94936`.)

are now deprecated. They should be replaced by the new macros
