Updates the requirements on asgiref to permit the latest version.

Sourced from asgiref's changelog.

3.11.1 (2026-02-03)

• SECURITY FIX CVE-2025-14550: There was a potential DoS vector for users of the asgiref.wsgi.WsgiToAsgi adapter. Malicious requests, including an unreasonably large number of values for the same header, could lead to resource exhaustion when building the WSGI environment.

  To mitigate this, the algorithm is changed to be more efficient, and WsgiToAsgi gains a new optional duplicate_header_limit parameter, which defaults to 100. This specifies the number of times a single header may be repeated before the request is rejected as malformed.

  You may override duplicate_header_limit when configuring your application::

  application = WsgiToAsgi(wsgi_app, duplicate_header_limit=200)
  

  Set duplicate_header_limit=None if you wish to disable this check.

• Fixed a regression in 3.11.0 in sync_to_async when wrapping a callable with an attribute named context. (#537)

3.11.0 (2025-11-19)

• sync_to_async gains a context parameter, similar to those for asyncio.create_task, TaskGroup &co, that can be used on Python 3.11+ to control the context used by the underlying task.

  The parent context is already propagated by default but the additional control is useful if multiple sync_to_async calls need to share the same context, e.g. when used with asyncio.gather().

3.10.0 (2025-10-05)

• Added AsyncSingleThreadContext context manager to ensure multiple AsyncToSync invocations use the same thread. (#511)

3.9.2 (2025-09-23)

• Adds support for Python 3.14.

• Fixes wsgi.errors file descriptor in WsgiToAsgi adapter.

3.9.1 (2025-07-08)

• Fixed deletion of Local values affecting other contexts. (#523)
