- Update to 3.12.0b4:
  - gh-issue-102988: CVE-2023-27043 (bsc#1210638): Prevent
    :func:`email.utils.parseaddr` and
    :func:`email.utils.getaddresses` from returning the realname
    portion of an invalid RFC2822 email header in the email
    address portion of the 2-tuple returned after being parsed by
    :class:`email._parseaddr.AddressList`.
  - gh-issue-106396: When the format specification of an
    f-string expression is empty, the parser now generates an
    empty :class:`ast.JoinedStr` node for it instead of an
    one-element :class:`ast.JoinedStr` with an empty string
    :class:`ast.Constant`.
  - gh-issue-106145: Make ``end_lineno`` and ``end_col_offset``
    required on ``type_param`` ast nodes.
  - gh-issue-105979: Fix crash in :func:`!_imp.get_frozen_object`
    due to improper exception handling.
  - gh-issue-98931: Ensure custom :exc:`SyntaxError` error
    messages are raised for invalid imports with multiple
    targets. Patch by Pablo Galindo
  - gh-issue-105908: Fixed bug where :gh:`99111` breaks future
    import ``barry_as_FLUFL`` in the Python REPL.
  - gh-issue-105340: Include the comprehension iteration
    variable in ``locals()`` inside a module- or class-scope
    comprehension.
  - gh-issue-105486: Change the repr of ``ParamSpec`` list of
    args in ``types.GenericAlias``.
  - gh-issue-101006: Improve error handling when read
    :mod:`marshal` data.
  - gh-issue-106524: Fix crash in :func:`!_sre.template` with
    templates containing invalid group indices.
  - gh-issue-106510: Improve debug output for atomic groups in
    regular expressions.
  - gh-issue-106503: Fix ref cycle in
    :class:`!asyncio._SelectorSocketTransport` by removing
    ``_write_ready`` in ``close``.
  - gh-issue-105497: Fix flag mask inversion when unnamed flags
    exist.
  - gh-issue-90876: Prevent :mod:`multiprocessing.spawn` from
    failing to *import* in environments where ``sys.executable``
    is ``None``.  This regressed in 3.11 with the addition of
    support for path-like objects in multiprocessing.
  - gh-issue-106292: Check for an instance-dict
    cached value in the :meth:`__get__` method of
    :func:`functools.cached_property`. This better matches the
    pre-3.12 behavior and improves compatibility for users
    subclassing :func:`functools.cached_property` and adding a
    :meth:`__set__` method.
  - gh-issue-106330: Fix incorrect matching of empty paths in
    :meth:`pathlib.PurePath.match`. This bug was introduced in
    Python 3.12.0 beta 1.
  - gh-issue-102541: Make pydoc.doc catch bad module ImportError
    when output stream is not None.
  - gh-issue-106152: Added PY_THROW event hook for
    :mod:`cProfile` for generators
  - gh-issue-106075: Added `asyncio.taskgroups.__all__` to
    `asyncio.__all__` for export in star imports.
  - gh-issue-105987: Fix crash due to improper reference counting
    in :mod:`asyncio` eager task factory internal routines.
  - gh-issue-105974: Fix bug where a :class:`typing.Protocol`
    class that had one or more non-callable members would
    raise :exc:`TypeError` when :func:`issubclass` was called
    against it, even if it defined a custom ``__subclasshook__``
    method. The behaviour in Python 3.11 and lower -- which has
    now been restored -- was not to raise :exc:`TypeError` in
    these situations if a custom ``__subclasshook__`` method was
    defined. Patch by Alex Waygood.
  - gh-issue-96145: Reverted addition of ``json.AttrDict``.
  - gh-issue-105497: Fix flag inversion when alias/mask members
    exist.
  - gh-issue-104554: Add RTSPS scheme support in urllib.parse
  - gh-issue-94777: Fix hanging :mod:`multiprocessing`
    ``ProcessPoolExecutor`` when a child process crashes while
    data is being written in the call queue.
  - gh-issue-106232: Make timeit doc command lines compatible
    with Windows by using double quotes for arguments.  This
    works on linux and macOS also.
  - gh-issue-101634: When running the Python test suite with
    ``-jN`` option, if a worker stdout cannot be decoded from
    the locale encoding report a failed testn so the exitcode is
    non-zero. Patch by Victor Stinner.
  - gh-issue-106118: Fix compilation for platforms without
    :data:`!O_CLOEXEC`. The issue was introduced with Python
    3.12b1 in :gh:`103295`. Patch by Erlend Aasland.
  - gh-issue-104692: Include ``commoninstall`` as a prerequisite
    for ``bininstall``
    This ensures that ``commoninstall`` is completed before
    ``bininstall`` is started when parallel builds are used (``make
    -j install``), and so the ``python3`` symlink is only installed
    after all standard library modules are installed.
  - gh-issue-106359: Argument Clinic now explicitly forbids
    "kwarg splats" in function calls used as annotations.
  - gh-issue-105227: The new :c:func:`PyType_GetDict` provides
    the dictionary for the given type object that is normally
    exposed by ``cls.__dict__``. Normally it's sufficient to
    use :c:member:`~PyTypeObject.tp_dict`, but for the static
    builtin types :c:member:`!tp_dict` is now always ``NULL``.
    :c:func:`!PyType_GetDict()` provides the correct dict object
    instead.
