This release focuses on compatibility with the upcoming release of
Python 3.13. Most changes are related to the implementation of type
parameter defaults (PEP 696).
Thanks to all of the people who contributed patches, especially Alex
Waygood, who did most of the work adapting typing-extensions to the
CPython PEP 696 implementation.
There is a single change since 4.12.0rc1:
Fix incorrect behaviour of typing_extensions.ParamSpec on Python 3.8 and
3.9 that meant that
isinstance(typing_extensions.ParamSpec("P"), typing.TypeVar) would have a
different result in some situations depending on whether or not a profiling
function had been set using sys.setprofile. Patch by Alex Waygood.
Changes included in 4.12.0rc1:
Improve the implementation of type parameter defaults (PEP 696)
Backport the typing.NoDefault sentinel object from Python 3.13.
TypeVars, ParamSpecs and TypeVarTuples without default values now have
their __default__ attribute set to this sentinel value.
TypeVars, ParamSpecs and TypeVarTuples now have a has_default()
method, matching typing.TypeVar, typing.ParamSpec and
typing.TypeVarTuple on Python 3.13+.
TypeVars, ParamSpecs and TypeVarTuples with default=None passed to
their constructors now have their __default__ attribute set to None
at runtime rather than types.NoneType.
Fix most tests for TypeVar, ParamSpec and TypeVarTuple on Python
3.13.0b1 and newer.
Backport CPython PR #118774,
allowing type parameters without default values to follow those with
default values in some type parameter lists. Patch by Alex Waygood,
backporting a CPython PR by Jelle Zijlstra.
It is now disallowed to use a TypeVar with a default value after a
TypeVarTuple in a type parameter list. This matches the CPython
implementation of PEP 696 on Python 3.13+.
Fix bug in PEP-696 implementation where a default value for a ParamSpec
would be cast to a tuple if a list was provided.
Patch by Alex Waygood.
Fix Protocol tests on Python 3.13.0a6 and newer. 3.13.0a6 adds a new
__static_attributes__ attribute to all classes in Python,
which broke some assumptions made by the implementation of
typing_extensions.Protocol. Similarly, 3.13.0b1 adds the new
__firstlineno__ attribute to all classes.
Fix AttributeError when using typing_extensions.runtime_checkable
in combination with typing.Protocol on Python 3.12.2 or newer.
Patch by Alex Waygood.
At runtime, assert_never now includes the repr of the argument
This release is mostly the same as 4.12.0rc1 but fixes one more
longstanding bug.
Fix incorrect behaviour of typing_extensions.ParamSpec on Python 3.8 and
3.9 that meant that
isinstance(typing_extensions.ParamSpec("P"), typing.TypeVar) would have a
different result in some situations depending on whether or not a profiling
function had been set using sys.setprofile. Patch by Alex Waygood.

Added the BlockingPortalProvider class to aid with constructing synchronous counterparts to asynchronous interfaces that would otherwise require multiple blocking portals
Added __slots__ to AsyncResource so that child classes can use __slots__ (#733; PR by Justin Su)
Added the TaskInfo.has_pending_cancellation() method
Fixed erroneous RuntimeError: called 'started' twice on the same task status when cancelling a task in a TaskGroup created with the start() method before the first checkpoint is reached after calling task_status.started() (#706; PR by Dominik Schwabe)
Fixed two bugs with TaskGroup.start() on asyncio:
Fixed erroneous RuntimeError: called 'started' twice on the same task status when cancelling a task in a TaskGroup created with the start() method before the first checkpoint is reached after calling task_status.started() (#706; PR by Dominik Schwabe)
Fixed the entire task group being cancelled if a TaskGroup.start() call gets cancelled (#685, #710)
Fixed a race condition that caused crashes when multiple event loops of the same backend were running in separate threads and simultaneously attempted to use AnyIO for their first time (#425; PR by David Jiricek and Ganden Schaffner)
Fixed cancellation delivery on asyncio incrementing the wrong cancel scope's cancellation counter when cascading a cancel operation to a child scope, thus failing to uncancel the host task (#716)
Fixed erroneous TypedAttributeLookupError if a typed attribute getter raises KeyError
Fixed the asyncio backend not respecting the PYTHONASYNCIODEBUG environment variable when setting the debug flag in anyio.run()
Fixed SocketStream.receive() not detecting EOF on asyncio if there is also data in the read buffer (#701)
Fixed MemoryObjectStream dropping an item if the item is delivered to a recipient that is waiting to receive an item but has a cancellation pending (#728)
Emit a ResourceWarning for MemoryObjectReceiveStream and MemoryObjectSendStream that were garbage collected without being closed (PR by Andrey Kazantcev)
Fixed MemoryObjectSendStream.send() not raising BrokenResourceError when the last corresponding MemoryObjectReceiveStream is closed while waiting to send a falsey item (#731; PR by Ganden Schaffner)
This library adheres to Semantic Versioning 2.0 <http://semver.org/>_.

Fix: nested matches of exclude patterns could exclude too much code, as
reported in issue 1779_. This is now fixed.
Changed: previously, coverage.py would consider a module docstring to be an
executable statement if it appeared after line 1 in the file, but not
executable if it was the first line. Now module docstrings are never counted
as executable statements. This can change coverage.py's count of the number
of statements in a file, which can slightly change the coverage percentage
reported.
In the HTML report, the filter term and "hide covered" checkbox settings are
remembered between viewings, thanks to Daniel Diniz <pull 1776_>_.
Python 3.13.0b1 is supported.
Fix: parsing error handling is improved to ensure bizarre source files are
handled gracefully, and to unblock oss-fuzz fuzzing, thanks to Liam DeVoe <pull 1788_>. Closes issue 1787.
v0.4.5 marks the official Beta release of ruff server, an integrated language server built into Ruff. ruff server supports the same feature set as ruff-lsp, powering linting, formatting, and code fixes in Ruff's editor integrations -- but with superior performance and no installation required. We'd love your feedback!
