# 2.0.1 Release Notes

Channels 2.0.1 is a patch release of channels, adding a couple of small new features and fixing one bug in URL resolution.

As always, when updating Channels make sure to also update its dependencies (`asgiref` and `daphne`) as these also get their own bugfix updates, and some bugs that may appear to be part of Channels are actually in those packages.

## New Features

- There are new async versions of the Websocket generic consumers, `AsyncWebsocketConsumer` and `AsyncJsonWebsocketConsumer`. Read more about them in Consumers.

- The old `allowed_hosts_only` decorator has been removed (it was accidentally included in the 2.0 release but didn’t work) and replaced with a new `OriginValidator` and `AllowedHostsOriginValidator` set of ASGI middleware. Read more in Security.

## Bugfixes

- A bug in `URLRouter` which didn’t allow you to match beyond the first URL in some situations has been resolved, and a test suite was added for URL resolution to prevent it happening again.

## Backwards Incompatible Changes

None.
