# 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.
