- Update to 3.9.13:
  - Core and Builtins
    - gh-92311: Fixed a bug where setting frame.f_lineno to jump
      over a list comprehension could misbehave or crash.
    - gh-92112: Fix crash triggered by an evil custom mro() on
      a metaclass.
    - gh-92036: Fix a crash in subinterpreters related to the
      garbage collector. When a subinterpreter is deleted,
      untrack all objects tracked by its GC. To prevent a crash
      in deallocator functions expecting objects to be tracked by
      the GC, leak a strong reference to these objects on
      purpose, so they are never deleted and their deallocator
      functions are not called. Patch by Victor Stinner.
    - gh-91421: Fix a potential integer overflow in
      _Py_DecodeUTF8Ex.
    - bpo-46775: Some Windows system error codes(>= 10000) are
      now mapped into the correct errno and may now raise
      a subclass of OSError. Patch by Dong-hee Na.
    - bpo-46962: Classes and functions that unconditionally
      declared their docstrings ignoring the
      --without-doc-strings compilation flag no longer do so.
    - The classes affected are pickle.PickleBuffer,
      testcapi.RecursingInfinitelyError, and types.GenericAlias.
    - The functions affected are 24 methods in ctypes.
    - Patch by Oleg Iarygin.
    - bpo-36819: Fix crashes in built-in encoders with error
      handlers that return position less or equal than the
      starting position of non-encodable characters.
  - Library
    - gh-91581: utcfromtimestamp() no longer attempts to resolve
      fold in the pure Python implementation, since the fold is
      never 1 in UTC. In addition to being slightly faster in the
      common case, this also prevents some errors when the
      timestamp is close to datetime.min. Patch by Paul Ganssle.
    - gh-92530: Fix an issue that occurred after interrupting
      threading.Condition.notify().
    - gh-92049: Forbid pickling constants re._constants.SUCCESS
      etc. Previously, pickling did not fail, but the result
      could not be unpickled.
    - bpo-47029: Always close the read end of the pipe used by
      multiprocessing.Queue after the last write of buffered data
      to the write end of the pipe to avoid BrokenPipeError at
      garbage collection and at multiprocessing.Queue.close()
      calls. Patch by Géry Ogam.
    - gh-91910: Add missing f prefix to f-strings in error
      messages from the multiprocessing and asyncio modules.
    - gh-91810: ElementTree method write() and function
      tostring() now use the text file’s encoding (“UTF-8” if not
      available) instead of locale encoding in XML declaration
      when encoding="unicode" is specified.
    - gh-91832: Add required attribute to argparse.Action repr
      output.
    - gh-91734: Fix OSS audio support on Solaris.
    - gh-91700: Compilation of regular expression containing
      a conditional expression (?(group)...) now raises an
      appropriate re.error if the group number refers to not
      defined group. Previously an internal RuntimeError was
      raised.
    - gh-91676: Fix unittest.IsolatedAsyncioTestCase to shutdown
      the per test event loop executor before returning from its
      run method so that a not yet stopped or garbage collected
      executor state does not persist beyond the test.
    - gh-90568: Parsing \N escapes of Unicode Named Character
      Sequences in a regular expression raises now re.error
      instead of TypeError.
    - gh-91595: Fix the comparison of character and integer
      inside Tools.gdb.libpython.write_repr(). Patch by Yu Liu.
    - gh-90622: Worker processes for
      concurrent.futures.ProcessPoolExecutor are no longer
      spawned on demand (a feature added in 3.9) when the
      multiprocessing context start method is "fork" as that can
      lead to deadlocks in the child processes due to a fork
      happening while threads are running.
    - gh-91575: Update case-insensitive matching in the re module
      to the latest Unicode version.
    - gh-91581: Remove an unhandled error case in the
      C implementation of calls to datetime.fromtimestamp with no
      time zone (i.e. getting a local time from an epoch
      timestamp). This should have no user-facing effect other
      than giving a possibly more accurate error message when
      called with timestamps that fall on 10000-01-01 in the
      local time. Patch by Paul Ganssle.
    - bpo-34480: Fix a bug where _markupbase raised an
      UnboundLocalError when an invalid keyword was found in
      marked section. Patch by Marek Suscak.
    - bpo-27929: Fix asyncio.loop.sock_connect() to only resolve
      names for socket.AF_INET or socket.AF_INET6 families.
      Resolution may not make sense for other families, like
      socket.AF_BLUETOOTH and socket.AF_UNIX.
    - bpo-43323: Fix errors in the email module if the charset
      itself contains undecodable/unencodable characters.
    - bpo-46787: Fix concurrent.futures.ProcessPoolExecutor
      exception memory leak
    - bpo-46415: Fix ipaddress.ip_{address,interface,network}
      raising TypeError instead of ValueError if given invalid
      tuple as address parameter.
    - bpo-44911: IsolatedAsyncioTestCase will no longer throw an
      exception while cancelling leaked tasks. Patch by Bar
      Harel.
    - bpo-44493: Add missing terminated NUL in sockaddr_un’s
      length
    - This was potentially observable when using non-abstract
      AF_UNIX datagram sockets to processes written in another
      programming language.
    - bpo-42627: Fix incorrect parsing of Windows registry proxy
      settings
    - bpo-36073: Raise ProgrammingError instead of segfaulting on
      recursive usage of cursors in sqlite3 converters. Patch by
      Sergey Fedoseev.
  - Documentation
    - gh-91888: Add a new gh role to the documentation to link to
      GitHub issues.
    - gh-91783: Document security issues concerning the use of
      the function shutil.unpack_archive()
    - gh-91547: Remove “Undocumented modules” page.
    - bpo-44347: Clarify the meaning of dirs_exist_ok, a kwarg of
      shutil.copytree().
    - bpo-38668: Update the introduction to documentation for
      os.path to remove warnings that became irrelevant after the
      implementations of PEP 383 and PEP 529.
    - bpo-47138: Pin Jinja to a version compatible with Sphinx
      version 2.4.4.
    - bpo-46962: All docstrings in code snippets are now wrapped
      into PyDoc_STR() to follow the guideline of PEP 7’s
      Documentation Strings paragraph. Patch by Oleg Iarygin.
    - bpo-26792: Improve the docstrings of runpy.run_module() and
      runpy.run_path(). Original patch by Andrew Brezovsky.
    - bpo-45790: Adjust inaccurate phrasing in Defining Extension
      Types: Tutorial about the ob_base field and the macros used
      to access its contents.
    - bpo-42340: Document that in some circumstances
      KeyboardInterrupt may cause the code to enter an
      inconsistent state. Provided a sample workaround to avoid
      it if needed.
    - bpo-41233: Link the errnos referenced in
      Doc/library/exceptions.rst to their respective section in
      Doc/library/errno.rst, and vice versa. Previously this was
      only done for EINTR and InterruptedError. Patch by Yan
      “yyyyyyyan” Orestes.
    - bpo-38056: Overhaul the Error Handlers documentation in
      codecs.
    - bpo-13553: Document tkinter.Tk args.
  - Tests
    - gh-91607: Fix test_concurrent_futures to test the correct
      multiprocessing start method context in several cases where
      the test logic mixed this up.
    - bpo-47205: Skip test for sched_getaffinity() and
      sched_setaffinity() error case on FreeBSD.
    - bpo-29890: Add tests for ipaddress.IPv4Interface and
      ipaddress.IPv6Interface construction with tuple arguments.
      Original patch and tests by louisom.
  - Build
    - bpo-47103: Windows PGInstrument builds now copy a required
      DLL into the output directory, making it easier to run the
      profile stage of a PGO build.
  - Windows
    - bpo-47194: Update zlib to v1.2.12 to resolve
      CVE-2018-25032.
    - bpo-46785: Fix race condition between os.stat() and
      unlinking a file on Windows, by using errors codes returned
      by FindFirstFileW() when appropriate in win32_xstat_impl.
    - bpo-40859: Update Windows build to use xz-5.2.5
  - Tools/Demos
