-inspect
--------
-
-* Add :func:`inspect.markcoroutinefunction` to mark sync functions that return
-  a :term:`coroutine` for use with :func:`inspect.iscoroutinefunction`.
-  (Contributed Carlton Gibson in :gh:`99247`.)
-
-* Add :func:`inspect.getasyncgenstate` and :func:`inspect.getasyncgenlocals`
-  for determining the current state of asynchronous generators.
-  (Contributed by Thomas Krennwallner in :issue:`35759`.)
-
-* The performance of :func:`inspect.getattr_static` has been considerably
-  improved. Most calls to the function should be at least 2x faster than they
-  were in Python 3.11, and some may be 6x faster or more. (Contributed by Alex

-pathlib
--------
-
-* Add support for subclassing :class:`pathlib.PurePath` and
-  :class:`~pathlib.Path`, plus their Posix- and Windows-specific variants.
-  Subclasses may override the :meth:`~pathlib.PurePath.with_segments` method
-  to pass information between path instances.
-
-* Add :meth:`~pathlib.Path.walk` for walking the directory trees and generating
-  all file or directory names within them, similar to :func:`os.walk`.
-  (Contributed by Stanislav Zmiev in :gh:`90385`.)
-
-* Add *walk_up* optional parameter to :meth:`pathlib.PurePath.relative_to`
-  to allow the insertion of ``..`` entries in the result; this behavior is
-  more consistent with :func:`os.path.relpath`.
-  (Contributed by Domenico Ragusa in :issue:`40358`.)
-
-* Add :meth:`pathlib.Path.is_junction` as a proxy to :func:`os.path.isjunction`.
-  (Contributed by Charles Machalow in :gh:`99547`.)
-
-* Add *case_sensitive* optional parameter to :meth:`pathlib.Path.glob`,
-  :meth:`pathlib.Path.rglob` and :meth:`pathlib.PurePath.match` for matching
-  the path's case sensitivity, allowing for more precise control over the matching process.
