[dependabot]

Bumps asgiref from 3.8.1 to 3.9.2.

Changelog

Sourced from asgiref's changelog.

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)

• Skip CPython specific garbage collection test on pypy. (#521)

3.9.0 (2025-07-03)

• Adds support for Python 3.13.

• Drops support for (end-of-life) Python 3.8.

• Fixes an error with conflicting kwargs between AsyncToSync and the wrapped function. (#471)

• Fixes Local isolation between asyncio Tasks. (#478)

• Fixes a reference cycle in Local (#508)

• Fixes a deadlock in CurrentThreadExecutor with nested async_to_sync → sync_to_async → async_to_sync → create_task calls. (#494)

• The ApplicationCommunicator testing utility will now return the task result if it's already completed on send_input and receive_nothing. You may need to catch (e.g.) the asyncio.exceptions.CancelledError if sending messages to already finished consumers in your tests. (#505)
