2.1.4 Release Notes

Channels 2.1.4 is another bugfix release in the 2.1 series.

Bugfixes & Small Changes

  • Django middleware is now cached rather than instantiated per request resulting in a significant speed improvement. Some middleware took seconds to load and as a result Channels was unusable for HTTP serving before.

  • ChannelServerLiveTestCase now serves static files again.

  • Improved error message resulting from bad Origin headers.

  • runserver logging now goes through the Django logging framework to match modern Django.

  • Generic consumers can now have non-default channel layers - set the channel_layer_alias property on the consumer class

  • Improved error when accessing scope['user'] before it’s ready - the user is not accessible in the constructor of ASGI apps as it needs an async environment to load in. Previously it raised a generic error when you tried to access it early; now it tells you more clearly what’s happening.
