-
-Daphne 4.2 is a maintenance release in the 4.x series.
-
-* Added support for Python 3.13.
-
-* Dropped support for EOL Python 3.8.
-
-* Updated pyupgrade configuration to target Python 3.9.
-
-* Added a `load_asgi_app` hook to CLI class, useful for compiled or frozen
-  applications.
-
-* Allowed assigning a port in the DaphneProcess test helper, useful for live
-  server test cases, such as that provided by Channels.
-
-* Added --nostatic and --insecure args to runserver command to match Django's
-  built-in command.
-
-* Moved metadata to use pyproject.toml.

-
-* Added support for Python 3.12.
-
-* Dropped support for EOL Python 3.7.
-
-* Handled root path for websocket scopes.
-
-* Validate HTTP header names as per RFC 9110.
-
-4.0.0 (2022-10-07)
-------------------
-
-Major versioning targeting use with Channels 4.0 and beyond. Except where
-noted should remain usable with Channels v3 projects, but updating Channels to the latest version is recommended.
-
-* Added a ``runserver`` command to run an ASGI Django development server.
-
-  Added ``"daphne"`` to the ``INSTALLED_APPS`` setting, before
-  ``"django.contrib.staticfiles"`` to enable:
-
-  INSTALLED_APPS = [
-    "daphne",
-    ...
-  ]
-
-  This replaces the Channels implementation of ``runserver``, which is removed
-  in Channels 4.0.
-
-* Made the ``DaphneProcess`` tests helper class compatible with the ``spawn``
-  process start method, which is used on macOS and Windows.
-
-  Note that requires Channels v4 if using with ``ChannelsLiveServerTestCase``.
-
-* Dropped support for Python 3.6.
-
-* Updated dependencies to the latest versions.
-
-  Previously a range of Twisted versions have been supported. Recent Twisted
-  releases (22.2, 22.4) have issued security fixes, so those are now the
-  minimum supported version. Given the stability of Twisted, supporting a
-  range of versions does not represent a good use of maintainer time. Going
-  forward the latest Twisted version will be required.
-
-* Set ``daphne`` as default ``Server`` header.
-
-  This can be configured with the ``--server-name`` CLI argument.
-
-  Added the new ``--no-server-name`` CLI argument to disable the ``Server``
-  header, which is equivalent to ``--server-name=` (an empty name).
-
-* Added ``--log-fmt`` CLI argument.
-
-* Added support for ``ASGI_THREADS`` environment variable, setting the maximum
-  number of workers used by a ``SyncToAsync`` thread-pool executor.
-
-  Set e.g. ``ASGI_THREADS=4 daphne ...`` when running to limit the number of
-  workers.
-
-* Removed deprecated ``--ws_protocols`` CLI option.
-
-3.0.2 (2021-04-07)
-------------------
-
-* Fixed a bug where ``send`` passed to applications wasn't a true async
-  function but a lambda wrapper, preventing it from being used with
-  ``asgiref.sync.async_to_sync()``.
-
-
-3.0.1 (2020-11-12)
-------------------
-
-* Fixed a bug where ``asyncio.CancelledError`` was not correctly handled on
-  Python 3.8+, resulting in incorrect protocol application cleanup.
-
-
-3.0.0 (2020-10-28)
-------------------
-
-* Updates internals to use ASGI v3 throughout. ``asgiref.compatibility`` is
-  used for older applications.
-
-* Consequently, the `--asgi-protocol` command-line option is removed.
-
-* HTTP request bodies are now read, and passed to the application, in chunks.
-
-* Added support for Python 3.9.
-
-* Dropped support for Python 3.5.
-
-
-2.5.0 (2020-04-15)
-------------------
-
-* Fixes compatability for twisted when running Python 3.8+ on Windows, by
-  setting ``asyncio.WindowsSelectorEventLoopPolicy`` as the event loop policy
-  in this case.
-
-* The internal ``daphne.testing.TestApplication`` now requires an addition
-  ``lock`` argument to ``__init__()``. This is expected to be an instance of
-  ``multiprocessing.Lock``.
-
-
-2.4.1 (2019-12-18)
-------------------
-
-* Avoids Twisted using the default event loop, for compatibility with Django
-  3.0's ``async_unsafe()`` decorator in threaded contexts, such as using the
-  auto-reloader.

 Daphne is a HTTP, HTTP2 and WebSocket protocol server for
-`ASGI <https://github.com/django/asgiref/blob/main/specs/asgi.rst>`_ and
-`ASGI-HTTP <https://github.com/django/asgiref/blob/main/specs/www.rst>`_,

+`ASGI-HTTP <https://github.com/django/asgiref/blob/master/specs/www.rst>`_,
 developed to power Django Channels.
 
 It supports automatic negotiation of protocols; there's no need for URL
 prefixing to determine WebSocket endpoints versus HTTP endpoints.
 
+*Note:* Daphne 2 is not compatible with Channels 1.x applications, only with
+Channels 2.x and other ASGI applications. Install a 1.x version of Daphne
+for Channels 1.x support.
