+## Typing Council
+
+The Typing Council, set up in [PEP 729](https://peps.python.org/pep-0729/),
+oversees Python's type checking ecosystem as a whole. Typing PEPs are still
+accepted or rejected by the Steering Council, but only after consultation
+with the Typing Council, and typing-specific PEPs are expected to be sent to
+the Typing Council first.
+
+## C API Working Group
+
+The C API Working Group (created by and defined in [PEP
+731](https://peps.python.org/pep-0731/)) is a small committee of Python core
+developers responsible for overseeing and coordinating the development and
+maintenance of the Python C API. The Steering Council has in principle
+delegated all C API design and implementation decisions to the C API WG,
+although there is no standing PEP delegation (since the C API is rarely an
+isolated PEP topic).
+
+## Documentation Editorial Board
+
+The Documentation Editorial Board (described in [PEP
+732](https://peps.python.org/pep-0732/) is in charge of the strategy,
+structure, style and governance of all of Python's user-facing documentation
+efforts. As with the C API WG there is no standing PEP delegation as there are
+few PEPs specific to the documentation efforts, but the Editorial Board has
+specific autonomy and authority as described in PEP 732.
