+PEP 594: dead batteries
+-----------------------
+
+* :pep:`594` removed 19 modules from the standard library,
+  deprecated in Python 3.11:
+
+  * :mod:`!aifc`.
+    (Contributed by Victor Stinner in :gh:`104773`.)
+
+  * :mod:`!audioop`.
+    (Contributed by Victor Stinner in :gh:`104773`.)
+
+  * :mod:`!chunk`.
+    (Contributed by Victor Stinner in :gh:`104773`.)
+
+  * :mod:`!cgi` and :mod:`!cgitb`.
+
+    * ``cgi.FieldStorage`` can typically be replaced with
+      :func:`urllib.parse.parse_qsl` for ``GET`` and ``HEAD`` requests,
+      and the :mod:`email.message` module or `multipart
+      <https://pypi.org/project/multipart/>`__ PyPI project for ``POST`` and
+      ``PUT``.
+
+    * ``cgi.parse()`` can be replaced by calling :func:`urllib.parse.parse_qs`
+      directly on the desired query string, except for ``multipart/form-data``
+      input, which can be handled as described for ``cgi.parse_multipart()``.
+
+    * ``cgi.parse_header()`` can be replaced with the functionality in the
+      :mod:`email` package, which implements the same MIME RFCs. For example,
+      with :class:`email.message.EmailMessage`::
+
+          from email.message import EmailMessage
+          msg = EmailMessage()
+          msg['content-type'] = 'application/json; charset="utf8"'
+          main, params = msg.get_content_type(), msg['content-type'].params
+
+    * ``cgi.parse_multipart()`` can be replaced with the functionality in the
+      :mod:`email` package (e.g. :class:`email.message.EmailMessage` and
+      :class:`email.message.Message`) which implements the same MIME RFCs, or
+      with the `multipart <https://pypi.org/project/multipart/>`__ PyPI project.
+
+    (Contributed by Victor Stinner in :gh:`104773`.)
+
+  * :mod:`!crypt` module and its private :mod:`!_crypt` extension.
+    The :mod:`hashlib` module is a potential replacement for certain use cases.
+    Otherwise, the following PyPI projects can be used:
+
+    * `bcrypt <https://pypi.org/project/bcrypt/>`_:
+      Modern password hashing for your software and your servers.
+    * `passlib <https://pypi.org/project/passlib/>`_:
+      Comprehensive password hashing framework supporting over 30 schemes.
+    * `argon2-cffi <https://pypi.org/project/argon2-cffi/>`_:
+      The secure Argon2 password hashing algorithm.
+    * `legacycrypt <https://pypi.org/project/legacycrypt/>`_:
+      Wrapper to the POSIX crypt library call and associated functionality.
+
+    (Contributed by Victor Stinner in :gh:`104773`.)
+
+  * :mod:`!imghdr`: use the projects
+    `filetype <https://pypi.org/project/filetype/>`_,
+    `puremagic <https://pypi.org/project/puremagic/>`_,
+    or `python-magic <https://pypi.org/project/python-magic/>`_ instead.
+    (Contributed by Victor Stinner in :gh:`104773`.)
+
+  * :mod:`!mailcap`.
+    The :mod:`mimetypes` module provides an alternative.
+    (Contributed by Victor Stinner in :gh:`104773`.)
+
+  * :mod:`!msilib`.
+    (Contributed by Zachary Ware in :gh:`104773`.)
+

+    (Contributed by Victor Stinner in :gh:`104773`.)
+
+  * :mod:`!nntplib`:
+    the `PyPI nntplib project <https://pypi.org/project/nntplib/>`_
+    can be used instead.
+    (Contributed by Victor Stinner in :gh:`104773`.)
+
+  * :mod:`!ossaudiodev`: use the
+    `pygame project <https://www.pygame.org/>`_ for audio playback.
+    (Contributed by Victor Stinner in :gh:`104780`.)
+
+  * :mod:`!pipes`: use the :mod:`subprocess` module instead.
+    (Contributed by Victor Stinner in :gh:`104773`.)
+
+  * :mod:`!sndhdr`: use the projects
+    `filetype <https://pypi.org/project/filetype/>`_,
