+++ /dev/null
-Add a ``strict`` option to ``batched()`` in the ``itertools`` module.
+++ /dev/null
-:func:`os.posix_spawn` now accepts ``env=None``, which makes the newly spawned
-process use the current process environment. Patch by Jakub Kulik.
+++ /dev/null
-Fix :func:`shutil.copymode` and :func:`shutil.copystat` on Windows.
-Previously they worked differenly if *dst* is a symbolic link:
-they modified the permission bits of *dst* itself
-rather than the file it points to if *follow_symlinks* is true or *src* is
-not a symbolic link, and did not modify the permission bits if
-*follow_symlinks* is false and *src* is a symbolic link.
+++ /dev/null
-Add support of :func:`os.fchmod` and a file descriptor in :func:`os.chmod`
-on Windows.
+++ /dev/null

-``http.client.HTTPResponse.readline`` close IO after reading all data when
-content length is known. Patch by Illia Volochii.
+++ /dev/null
-The :mod:`subprocess` module can now use the :func:`os.posix_spawn` function
-with ``close_fds=True`` on platforms where
-``posix_spawn_file_actions_addclosefrom_np`` is available.
-Patch by Jakub Kulik.
+++ /dev/null

-Patch by Carson Radtke.
+++ /dev/null
-Speed up :meth:`pathlib.Path.glob` by using :attr:`os.DirEntry.path` where possible.
+++ /dev/null
-:meth:`asyncio.futures.Future.set_exception()` now transforms :exc:`StopIteration`
-into :exc:`RuntimeError` instead of hanging or other misbehavior. Patch
-contributed by Jamie Phan.
+++ /dev/null
-Fixed tarfile list() method to show file type.

+++ /dev/null
-Fix regression in Python 3.12 where :class:`~typing.Protocol` classes that
-were not marked as :func:`runtime-checkable <typing.runtime_checkable>`
-would be unnecessarily introspected, potentially causing exceptions to be
-raised if the protocol had problematic members. Patch by Alex Waygood.
+++ /dev/null
-Fix import of :mod:`unittest.mock` when CPython is built without docstrings.
+++ /dev/null
-Fix segfaults in the ``_elementtree`` module.
-Fix first segfault during deallocation of ``_elementtree.XMLParser`` instances by keeping strong reference
-to ``pyexpat`` module in module state for capsule lifetime.
-Fix second segfault which happens in the same deallocation process by keeping strong reference
-to ``_elementtree`` module in ``XMLParser`` structure for ``_elementtree`` module lifetime.
+++ /dev/null
-Fix multiprocessing logger for ``%(filename)s``.
+++ /dev/null
-When a second reference to a string appears in the input to :mod:`pickle`,
-and the Python implementation is in use,
-we are guaranteed that a single copy gets pickled
-and a single object is shared when reloaded.
-Previously, in protocol 0, when a string contained certain characters
-(e.g. newline) it resulted in duplicate objects.
+++ /dev/null
-Make sure that ``webbrowser.MacOSXOSAScript`` sends ``webbrowser.open``
-audit event.
+++ /dev/null
-Raise audit events from :class:`pathlib.Path` and not its private base class
-``PathBase``.
+++ /dev/null
-Increase the backlog for :class:`multiprocessing.connection.Listener` objects created
-by :mod:`multiprocessing.manager` and :mod:`multiprocessing.resource_sharer` to
-significantly reduce the risk of getting a connection refused error when creating
-a :class:`multiprocessing.connection.Connection` to them.
+++ /dev/null
-Indicate if there were no actual calls in unittest
-:meth:`~unittest.mock.Mock.assert_has_calls` failure.
+++ /dev/null
-Add default implementations of :meth:`pickle.Pickler.persistent_id` and
-:meth:`pickle.Unpickler.persistent_load` methods in the C implementation.
-Calling ``super().persistent_id()`` and ``super().persistent_load()`` in
-subclasses of the C implementation of :class:`pickle.Pickler` and
-:class:`pickle.Unpickler` classes no longer causes infinite recursion.
+++ /dev/null
-Support loads ``str`` in :func:`plistlib.loads`.
+++ /dev/null
-Fix resource warnings for unclosed files in :mod:`pickle` and
-:mod:`pickletools` command line interfaces.
+++ /dev/null
-Add support for the *allow_code* argument in the :mod:`marshal` module.
-Passing ``allow_code=False`` prevents serialization and de-serialization of
-code objects which is incompatible between Python versions.
+++ /dev/null
-In :meth:`asyncio.StreamReaderProtocol.connection_made`, there is callback
-that logs an error if the task wrapping the "connected callback" fails. This
-callback would itself fail if the task was cancelled. Prevent this by
-checking whether the task was cancelled first. If so, close the transport
-but don't log an error.
+++ /dev/null
-Fix :exc:`UnicodeEncodeError` in :mod:`email` when re-fold lines that
-contain unknown-8bit encoded part followed by non-unknown-8bit encoded part.
+++ /dev/null
-Raise deprecation warnings from :class:`pathlib.PurePath` and not its
-private base class ``PurePathBase``.
+++ /dev/null

-a "/" directory entry in them as is commonly added to zips by some wiki or
-bug tracker data exporters.
+++ /dev/null
-Add ``CLOCK_MONOTONIC_RAW_APPROX`` and ``CLOCK_UPTIME_RAW_APPROX`` to
-:mod:`time` on macOS. These are clocks available on macOS 10.12 or later.

+++ /dev/null
-Silence unraisable AttributeError when warnings are emitted during Python
-finalization.
+++ /dev/null
-Insert :exc:`TimeoutError` in the context of the exception that was raised
-during exiting an expired :func:`asyncio.timeout` block.
+++ /dev/null
-unittest runner: Don't exit 5 if tests were skipped. The intention of
-exiting 5 was to detect issues where the test suite wasn't discovered at
-all. If we skipped tests, it was correctly discovered.
+++ /dev/null
-:func:`asyncio.TaskGroup()` and :func:`asyncio.timeout()` context managers
-now handle :exc:`~asyncio.CancelledError` subclasses as well as exact
-:exc:`!CancelledError`.
+++ /dev/null

-``_compresslevel`` name remaining available as a property to retain
-compatibility.
+++ /dev/null
-:meth:`sqlite3.Connection.iterdump` now ensures that foreign key support is
-disabled before dumping the database schema, if there is any foreign key
-violation. Patch by Erlend E. Aasland and Mariusz Felisiak.
+++ /dev/null
-Fixed a bug in :class:`fractions.Fraction` where an invalid string using ``d`` in the decimals part creates a different error compared to other invalid letters/characters. Patch by Jeremiah Gabriel Pascual.
+++ /dev/null
-:mod:`plistlib` now supports loading more deeply nested lists in binary
-format.
+++ /dev/null
-Fix possible :exc:`OverflowError` in :meth:`socket.socket.sendfile` when pass
-*count* larger than 2 GiB on 32-bit platform.

-Test modes that file can get with chmod() on Windows.
+++ /dev/null
-Fixed order dependence in running tests in the same process
-when a test that has submodules (e.g. test_importlib) follows a test that
-imports its submodule (e.g. test_importlib.util) and precedes a test
-(e.g. test_unittest or test_compileall) that uses that submodule.
+++ /dev/null
-Adds a regression test to verify that ``vfork()`` is used when expected by
-:mod:`subprocess` on vfork enabled POSIX systems (Linux).
+++ /dev/null
-The tests now correctly compare zlib version when
-:const:`zlib.ZLIB_RUNTIME_VERSION` contains non-integer suffixes. For
-example zlib-ng defines the version as ``1.3.0.zlib-ng``.
+++ /dev/null
-Fix ``test_tarfile_vs_tar`` in ``test_shutil`` for macOS, where system tar
-can include more information in the archive than :mod:`shutil.make_archive`.
+++ /dev/null
-Use module state for the _testcapi extension module.
+++ /dev/null
-Fix :func:`os.path.isabs` incorrectly returning ``True`` when given a path
-that starts with exactly one (back)slash on Windows.
-
-Fix :meth:`pathlib.PureWindowsPath.is_absolute` incorrectly returning
-``False`` for some paths beginning with two (back)slashes.
+++ /dev/null
-Specify a low recursion depth for ``test_bad_getattr()`` in
-``test.pickletester`` to avoid exhausting the stack under a pydebug build
-for WASI.
+++ /dev/null
-Lower the recursion limit in ``test_isinstance`` for
-``test_infinitely_many_bases()``. This prevents a stack overflow on a
-pydebug build of WASI.
+++ /dev/null
-Disable ``test_super_deep()`` from ``test_call`` under pydebug builds on
-WASI; the stack depth is too small to make the test useful.
+++ /dev/null
-Fix mojibake in :class:`mmap.mmap` when using a non-ASCII *tagname* argument
-on Windows.
+++ /dev/null
-Correctly sort and remove duplicate environment variables in
-:py:func:`!_winapi.CreateProcess`.
+++ /dev/null

-incorrect ThemeChanged warnings.
+++ /dev/null
-Fixes path calculations when launching Python on Windows through a symlink.
+++ /dev/null
-:mod:`multiprocessing`: On Windows, fix a race condition in
-``Process.terminate()``: no longer set the ``returncode`` attribute to
-always call ``WaitForSingleObject()`` in ``Process.wait()``. Previously,
-sometimes the process was still running after ``TerminateProcess()`` even if
-``GetExitCodeProcess()`` is not ``STILL_ACTIVE``. Patch by Victor Stinner.
+++ /dev/null
-Update Windows installer to use SQLite 3.44.2.
+++ /dev/null
-:func:`os.stat` calls were returning incorrect time values for files that
-could not be accessed directly.
+++ /dev/null
-Process privileges that are activated for creating directory junctions are
-now restored afterwards, avoiding behaviour changes in other parts of the
-program.
+++ /dev/null
-Use ``/dev/fd`` on macOS to determine the number of open files in
-``test.support.os_helper.fd_count`` to avoid a crash with "guarded" file
-descriptors when probing for open files.
+++ /dev/null
-Make sure the preprocessor definitions for ``ALIGNOF_MAX_ALIGN_T``,
-``SIZEOF_LONG_DOUBLE`` and ``HAVE_GCC_ASM_FOR_X64`` are correct for
-Universal 2 builds on macOS.
+++ /dev/null
-Disable a signal handling stress test on macOS due to a bug in macOS
-(FB13453490).
+++ /dev/null
-Make sure the result of :func:`sysconfig.get_plaform` includes at least a
-major and minor versions, even if ``MACOSX_DEPLOYMENT_TARGET`` is set to
-only a major version during build to match the format expected by pip.
+++ /dev/null
-Set ``CFBundleAllowMixedLocalizations`` to true in the Info.plist for the
-framework, embedded Python.app and IDLE.app with framework installs on
-macOS. This allows applications to pick up the user's preferred locale when
-that's different from english.
+++ /dev/null
-Update macOS installer to use SQLite 3.44.2.
+++ /dev/null
-webbrowser: Don't look for X11 browsers on macOS. Those are generally not
-used and probing for them can result in starting XQuartz even if it isn't
-used otherwise.
+++ /dev/null
-The :program:`freeze` tool doesn't work with framework builds of Python.
-Document this and bail out early when running the tool with such a build.
+++ /dev/null
-Document that :mod:`dbm.ndbm` can silently corrupt DBM files on updates when
-exceeding undocumented platform limits, and can crash (segmentation fault)
-when reading such a corrupted file. (FB8919203)
+++ /dev/null
-Running ``configure ... --with-openssl-rpath=X/Y/Z`` no longer fails to detect
-OpenSSL on macOS.

-``UF_TRACKED``, ``UF_DATAVAULT``, ``SF_SUPPORTED``, ``SF_SETTABLE``,
-``SF_SYNTHETIC``, ``SF_RESTRICTED``, ``SF_FIRMLINK`` and ``SF_DATALESS``.
-The values ``UF_SETTABLE``, ``SF_SUPPORTED``, ``SF_SETTABLE`` and
