+
+Fixed an issue where instances of :class:`ssl.SSLSocket` were vulnerable to
+a bypass of the TLS handshake and included protections (like certificate
+verification) and treating sent unencrypted data as if it were
+post-handshake TLS encrypted data.  Security issue reported as
+`CVE-2023-40217
+<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2023-40217>`_ by Aapo
+Oksman. Patch by Gregory P. Smith.

+PEP 669 specifies that ``sys.monitoring.register_callback`` will generate an
+audit event. Pre-releases of Python 3.12 did not generate the audit event.

+The "pending call" machinery now works for all interpreters, not just the
+main interpreter, and runs in all threads, not just the main thread. Some
+calls are still only done in the main thread, ergo in the main interpreter.
+This change does not affect signal handling nor the existing public C-API
+(``Py_AddPendingCall()``), which both still only target the main thread. The
+new functionality is meant strictly for internal use for now, since
+consequences of its use are not well understood yet outside some very
+restricted cases.  This change brings the capability in line with the
+intention when the state was made per-interpreter several years ago.

+``PyTypeObject.tp_bases`` (and ``tp_mro``) for builtin static types are now
+shared by all interpreters, whereas in 3.12-beta1 they were stored on
+``PyInterpreterState``.  Also note that now the tuples are immortal objects.

+``PY_SSIZE_T_CLEAN`` is no longer required to use ``'#'`` formats in APIs
+like :c:func:`PyArg_ParseTuple` and :c:func:`Py_BuildValue`. They uses
+``Py_ssize_t`` for ``'#'`` regardless ``PY_SSIZE_T_CLEAN``.

+
+Don't call :c:var:`PyOS_InputHook` or :c:var:`PyOS_ReadlineFunctionPointer`
+in subinterpreters, since it's generally difficult to avoid using global
+state in their registered callbacks. This also avoids situations where
+extensions may find themselves running in a subinterpreter they don't
+support (or haven't yet been loaded in).

+Add :c:func:`PyModule_Add` function: similar to
+:c:func:`PyModule_AddObjectRef` and :c:func:`PyModule_AddObject`, but always
+steals a reference to the value.
