+v13.1.0
+-------
+
+Features:
+
+- Allow passing Python objects around using `Frame.opaque` and `Packet.opaque`.
+- Allow extradata to be set by encoders by @daveisfera in (:issue:`1526`).
+
+Fixes:
+
+- Remove the `deprecation` module in anticipation of `PEP 702 <https://peps.python.org/pep-0702/>`_
+- Add type stubs to previously unannotated API sections.
+- Improve type stubs for both `mypy` and `mypy --strict`.
+- Permit only setting `time_base` with a Fraction, as mypy is unable to respect different types in getters vs setters.
+- Declare `write_packet` function as const by @hmaarrfk in (:issue:`1517`).
