* Dropped support for Python 3.8 (as #698 cannot be resolved
without cancel message support)
* Fixed 100% CPU use on asyncio while waiting for an exiting task
group to finish while said task group is within a cancelled
cancel scope (#695)
* Fixed cancel scopes on asyncio not propagating CancelledError
on exit when the enclosing cancel scope has been effectively
cancelled (#698)
* Fixed asyncio task groups not yielding control to the event
loop at exit if there were no child tasks to wait on
* Fixed inconsistent task uncancellation with asyncio cancel
scopes belonging to a task group when said task group has child
tasks running
- update to 4.5.0:
* Improved the performance of anyio.Lock and anyio.Semaphore on
asyncio (even up to 50 %)
* Added the fast_acquire parameter to anyio.Lock and
anyio.Semaphore to further boost performance at the expense of
safety (acquire() will not yield control back if there is no
contention)
* Added support for the from_uri(), full_match(), parser
methods/properties in anyio.Path, newly added in Python 3.13
(#737)
* Added support for more keyword arguments for run_process() and
open_process(): startupinfo, creationflags, pass_fds, user,
group, extra_groups and umask (#742)
* Improved the type annotations and support for PathLike in
run_process() and open_process() to allow for path-like
arguments, just like subprocess.Popen

* Adapted to API changes made in Trio v0.23
* Removed a checkpoint when exiting a task group
* Renamed the ``cancellable`` argument in
``anyio.to_thread.run_sync()`` to
* ``abandon_on_cancel`` (and deprecated the old parameter name)
* Added support for voluntary thread cancellation via
* ``anyio.from_thread.check_cancelled()``
* Bumped minimum version of trio to v0.23
* Exposed the ``ResourceGuard`` class in the public API
* Fixed ``RuntimeError: Runner is closed`` when running higher-
scoped async generator fixtures in some cases
* Fixed discrepancy between ``asyncio`` and ``trio`` where
reraising a cancellation exception in an ``except*`` block
would incorrectly bubble out of its cancel scope
* Any exceptions raising out of a task groups are now nested
inside an ``ExceptionGroup`` (or ``BaseExceptionGroup`` if one
or more ``BaseException`` were included)
* Fixed task group not raising a cancellation exception on
asyncio at exit if no child tasks were spawned and an outer
cancellation scope had been cancelled before
* Ensured that exiting a ``TaskGroup`` always hits a yield
point, regardless of whether there are running child tasks to
be waited on
* On asyncio, cancel scopes will defer cancelling tasks that
are scheduled to resume with a finished future
* On asyncio and Python 3.9/3.10, cancel scopes now only
suppress cancellation exceptions if the cancel message matches
the scope
* Task groups on all backends now raise a single cancellation

as accepting ``Coroutine[Any, Any, Any]`` as the return type

causing ``AttributeError: 'NonBaseMultiError' object has no attribute '_exceptions'``

that does not contain the ``exception`` key
- Fixed ``TypeError`` in ``get_current_task()`` on asyncio when using a custom ``Task`` factory

* ``stdin``, ``stdout`` and ``stderr`` now accept file-like objects
