+Pending Removal in Python 3.14
+------------------------------
+
+* :mod:`argparse`: The *type*, *choices*, and *metavar* parameters
+  of :class:`!argparse.BooleanOptionalAction` are deprecated
+  and will be removed in 3.14.
+  (Contributed by Nikita Sobolev in :gh:`92248`.)
+
+* :mod:`ast`: The following features have been deprecated in documentation
+  since Python 3.8, now cause a :exc:`DeprecationWarning` to be emitted at
+  runtime when they are accessed or used, and will be removed in Python 3.14:
+
+  * :class:`!ast.Num`
+  * :class:`!ast.Str`
+  * :class:`!ast.Bytes`
+  * :class:`!ast.NameConstant`
+  * :class:`!ast.Ellipsis`
+
+  Use :class:`ast.Constant` instead.
+  (Contributed by Serhiy Storchaka in :gh:`90953`.)
+
+* :mod:`collections.abc`: Deprecated :class:`!collections.abc.ByteString`.
+  Prefer :class:`!Sequence` or :class:`~collections.abc.Buffer`.
+  For use in typing, prefer a union, like ``bytes | bytearray``,
+  or :class:`collections.abc.Buffer`.
+  (Contributed by Shantanu Jain in :gh:`91896`.)
+
+* :mod:`email`: Deprecated the *isdst* parameter in :func:`email.utils.localtime`.
+  (Contributed by Alan Williams in :gh:`72346`.)
+
+* :mod:`importlib`: ``__package__`` and ``__cached__`` will cease to be set or
+  taken into consideration by the import system (:gh:`97879`).
+
+* :mod:`importlib.abc` deprecated classes:
+
+  * :class:`!importlib.abc.ResourceReader`
+  * :class:`!importlib.abc.Traversable`
+  * :class:`!importlib.abc.TraversableResources`
+
+  Use :mod:`importlib.resources.abc` classes instead:
+
+  * :class:`importlib.resources.abc.Traversable`
+  * :class:`importlib.resources.abc.TraversableResources`
+
+  (Contributed by Jason R. Coombs and Hugo van Kemenade in :gh:`93963`.)
+
+* :mod:`itertools` had undocumented, inefficient, historically buggy,
+  and inconsistent support for copy, deepcopy, and pickle operations.
+  This will be removed in 3.14 for a significant reduction in code
+  volume and maintenance burden.
+  (Contributed by Raymond Hettinger in :gh:`101588`.)
+
+* :mod:`multiprocessing`: The default start method will change to a safer one on
+  Linux, BSDs, and other non-macOS POSIX platforms where ``'fork'`` is currently
+  the default (:gh:`84559`). Adding a runtime warning about this was deemed too
+  disruptive as the majority of code is not expected to care. Use the
+  :func:`~multiprocessing.get_context` or
+  :func:`~multiprocessing.set_start_method` APIs to explicitly specify when
+  your code *requires* ``'fork'``.  See :ref:`multiprocessing-start-methods`.
+
+* :mod:`pathlib`: :meth:`~pathlib.PurePath.is_relative_to` and
+  :meth:`~pathlib.PurePath.relative_to`: passing additional arguments is
+  deprecated.
+
+* :mod:`pkgutil`: :func:`~pkgutil.find_loader` and :func:`~pkgutil.get_loader`
+  now raise :exc:`DeprecationWarning`;
+  use :func:`importlib.util.find_spec` instead.
+  (Contributed by Nikita Sobolev in :gh:`97850`.)
+
+* :mod:`pty`:
+
+  * ``master_open()``: use :func:`pty.openpty`.
+  * ``slave_open()``: use :func:`pty.openpty`.
+
+* :mod:`sqlite3`:
+
+  * :data:`!version` and :data:`!version_info`.
+
+  * :meth:`~sqlite3.Cursor.execute` and :meth:`~sqlite3.Cursor.executemany`
+    if :ref:`named placeholders <sqlite3-placeholders>` are used and
+    *parameters* is a sequence instead of a :class:`dict`.
+
+  * date and datetime adapter, date and timestamp converter:
+    see the :mod:`sqlite3` documentation for suggested replacement recipes.
+
+* :class:`types.CodeType`: Accessing :attr:`~codeobject.co_lnotab` was
+  deprecated in :pep:`626`
+  since 3.10 and was planned to be removed in 3.12,
+  but it only got a proper :exc:`DeprecationWarning` in 3.12.
+  May be removed in 3.14.
+  (Contributed by Nikita Sobolev in :gh:`101866`.)
+
+* :mod:`typing`: :class:`!typing.ByteString`, deprecated since Python 3.9,
+  now causes a :exc:`DeprecationWarning` to be emitted when it is used.
+
+* :mod:`urllib`:
+  :class:`!urllib.parse.Quoter` is deprecated: it was not intended to be a
+  public API.
+  (Contributed by Gregory P. Smith in :gh:`88168`.)

+Pending Removal in Python 3.15
+------------------------------
+
+* :class:`http.server.CGIHTTPRequestHandler` will be removed along with its
+  related ``--cgi`` flag to ``python -m http.server``.  It was obsolete and
+  rarely used.  No direct replacement exists.  *Anything* is better than CGI
+  to interface a web server with a request handler.
+
+* :class:`locale`: :func:`locale.getdefaultlocale` was deprecated in Python 3.11
+  and originally planned for removal in Python 3.13 (:gh:`90817`),
+  but removal has been postponed to Python 3.15.
+  Use :func:`locale.setlocale()`, :func:`locale.getencoding()` and
+  :func:`locale.getlocale()` instead.
+  (Contributed by Hugo van Kemenade in :gh:`111187`.)
+
+* :mod:`pathlib`:
+  :meth:`pathlib.PurePath.is_reserved` is deprecated and scheduled for
+  removal in Python 3.15. Use :func:`os.path.isreserved` to detect reserved
+  paths on Windows.
+
+* :mod:`platform`:
+  :func:`~platform.java_ver` is deprecated and will be removed in 3.15.
+  It was largely untested, had a confusing API,
+  and was only useful for Jython support.
+  (Contributed by Nikita Sobolev in :gh:`116349`.)
+
+* :mod:`threading`:
+  Passing any arguments to :func:`threading.RLock` is now deprecated.
+  C version allows any numbers of args and kwargs,
+  but they are just ignored. Python version does not allow any arguments.
+  All arguments will be removed from :func:`threading.RLock` in Python 3.15.
+  (Contributed by Nikita Sobolev in :gh:`102029`.)
+
+* :class:`typing.NamedTuple`:
+
+  * The undocumented keyword argument syntax for creating :class:`!NamedTuple` classes
+    (``NT = NamedTuple("NT", x=int)``) is deprecated, and will be disallowed in
+    3.15. Use the class-based syntax or the functional syntax instead.
+
+  * When using the functional syntax to create a :class:`!NamedTuple` class, failing to
+    pass a value to the *fields* parameter (``NT = NamedTuple("NT")``) is
+    deprecated. Passing ``None`` to the *fields* parameter
+    (``NT = NamedTuple("NT", None)``) is also deprecated. Both will be
+    disallowed in Python 3.15. To create a :class:`!NamedTuple` class with 0 fields, use
+    ``class NT(NamedTuple): pass`` or ``NT = NamedTuple("NT", [])``.
+
+* :class:`typing.TypedDict`: When using the functional syntax to create a
+  :class:`!TypedDict` class, failing to pass a value to the *fields* parameter (``TD =
+  TypedDict("TD")``) is deprecated. Passing ``None`` to the *fields* parameter
+  (``TD = TypedDict("TD", None)``) is also deprecated. Both will be disallowed
+  in Python 3.15. To create a :class:`!TypedDict` class with 0 fields, use ``class
+  TD(TypedDict): pass`` or ``TD = TypedDict("TD", {})``.
+
+* :mod:`wave`: Deprecate the ``getmark()``, ``setmark()`` and ``getmarkers()``
+  methods of the :class:`wave.Wave_read` and :class:`wave.Wave_write` classes.
+  They will be removed in Python 3.15.

+Pending Removal in Future Versions
+----------------------------------
+
+The following APIs were will be removed in the future,
+although there is currently no date scheduled for their removal.
+
+* :mod:`argparse`: Nesting argument groups and nesting mutually exclusive
+  groups are deprecated.
+
+* :mod:`builtins`:
+
+  * ``~bool``, bitwise inversion on bool.
+  * ``bool(NotImplemented)``.
+  * Generators: ``throw(type, exc, tb)`` and ``athrow(type, exc, tb)``
+    signature is deprecated: use ``throw(exc)`` and ``athrow(exc)`` instead,
+    the single argument signature.
+  * Currently Python accepts numeric literals immediately followed by keywords,
+    for example ``0in x``, ``1or x``, ``0if 1else 2``.  It allows confusing and
+    ambiguous expressions like ``[0x1for x in y]`` (which can be interpreted as
+    ``[0x1 for x in y]`` or ``[0x1f or x in y]``).  A syntax warning is raised
+    if the numeric literal is immediately followed by one of keywords
+    :keyword:`and`, :keyword:`else`, :keyword:`for`, :keyword:`if`,
+    :keyword:`in`, :keyword:`is` and :keyword:`or`.  In a future release it
+    will be changed to a syntax error. (:gh:`87999`)
+  * Support for ``__index__()`` and ``__int__()`` method returning non-int type:
+    these methods will be required to return an instance of a strict subclass of
+    :class:`int`.
+  * Support for ``__float__()`` method returning a strict subclass of
+    :class:`float`: these methods will be required to return an instance of
+    :class:`float`.

+
+* :class:`!pydoc.ErrorDuringImport`: A tuple value for *exc_info* parameter is
+  deprecated, use an exception instance.
+
+* :mod:`re`: More strict rules are now applied for numerical group references
+  and group names in regular expressions.  Only sequence of ASCII digits is now
+  accepted as a numerical reference.  The group name in bytes patterns and
+  replacement strings can now only contain ASCII letters and digits and
+  underscore.
