------------------
Channels 4 is the next major version of the Channels package. Together with the
matching Daphne v4 and channels-redis v4 releases, it updates dependencies,
fixes issues, and removes outdated code. It so provides the foundation for
Channels development going forward.
In most cases, you can update now by updating ``channels``, ``daphne``, and
``channels-redis`` as appropriate, with ``pip``, and by adding ``daphne`` at
the top of your ``INSTALLED_APPS`` setting.
First ``pip``::
pip install -U 'channels[daphne]' channels-redis
Then in your Django settings file::
INSTALLED_APPS = [
"daphne",
...
]
Again, this is a major version change. Amongst other changes, large amounts of
the Django-wrapping code deprecated in Channels v3 has now been removed, in
favour of Django's own ASGI handling, and the ``runserver`` command has been
moved into the Daphne package.
Please ensure to review the `Version 4.0.0 release notes
<https://channels.readthedocs.io/en/latest/releases/4.0.0.html>`_ for full
details.
