2.4.0 Release Notes
Channels 2.4 brings compatibility with Django 3.0s async_unsafe()
checks.
(Specifically we ensure session save calls are made inside an asgiref
database_sync_to_async()
.)
If you are using Daphne, it is recommended that you install Daphne version 2.4.1 or later for full compatibility with Django 3.0.
Backwards Incompatible Changes
In line with the guidance provided by Django’s supported versions policy we now also drop support for all Django versions before 2.2, which is the current LTS.
