+4.2.0 Release Notes
+===================
+
+Channels 4.2 introduces a couple of major but backwards-compatible
+changes, including most notably enhanced async suppport and fixing
+a long-standing bug where tests would try and close db connections
+and erroneously fail.
+
+Enhanced Async Support
+----------------------
+
+Support for asynchronous consumers has been greatly improved.
+The documentation has been updated to reflect the async ORM
+features added in Django 4.2. A new `channels.db.aclose_old_connections`
+function has been added to easily close old database connections
+in async consumers.
+
+Warning: Channels now automatically closes connections in async
+consumers before a new connection, after recieving message (but
+before dispatching to consumer code), and after disconnecting.
+
+This change has been made to more closely align with Django's
+request/response cycle, and to help users avoid attempting
+to use stale/broken connections.
+
+Notably, Channels does NOT close connections before or after
+a consumer **sends** data. This is to avoid database churn and
+more closely align with user expectations. Instead, users are
+expected to call `aclose_old_connections` occasionally during
+long-lived async connections.
+
+
+Bugfixes & Small Changes
+------------------------
+
+* Database connections are no longer closed inside tests, which
+  prevents erroneous "Cannot operate on a closed database" errors
+  when running tets.
+
+  Thanks to Jon Janzen.
+
+* An old import override and an unused deprecation message were removed
+
+  Thanks to @sevdog (Devid) and Jon Janzen.
+
+* WebsocketCommunicator now has informative `assert` error messages
+
+  Thanks to Karel Hovorka.
