- update to 3.6.0:
* Two new functions are added to the ``asgiref.sync`` module:
``iscoroutinefunction()`` and ``markcoroutinefunction()``.
* Python 3.12 deprecates ``asyncio.iscoroutinefunction()`` as an alias for
``inspect.iscoroutinefunction()``, whilst also removing the
``_is_coroutine`` marker. The latter is replaced with the
``inspect.markcoroutinefunction`` decorator.
* The new ``asgiref.sync`` functions are compatibility shims for these
functions that can be used until Python 3.12 is the minimum supported
version.
* The ``loop`` argument to ``asgiref.timeout.timeout`` is deprecated. As per
other ``asyncio`` based APIs, the running event loop is used by default.
Note that ``asyncio`` provides timeout utilities from Python 3.11, and
these should be preferred where available.
* Support for the ``ASGI_THREADS`` environment variable, used by
``SyncToAsync``, is removed. In general, a running event-loop is not
available to `asgiref` at import time, and so the default thread pool
executor cannot be configured. Protocol servers, or applications, should set
the default executor as required when configuring the event loop at
application startup.
