I didn't find any entries in the docs about these functions, so I just mentioned them, in "What's New".
* The :c:func:`PyCode_New` has a new parameter in the second position (*posonlyargcount*)
to support :pep:`570`, indicating the number of positional-only arguments.
+* The functions :c:func:`PyNode_AddChild` and :c:func:`PyParser_AddToken` now accept
+ two additional ``int`` arguments *end_lineno* and *end_col_offset*.
