-## Rails 5.1.0.beta1 (February 23, 2017) ##
-
-*   Redis subscription adapters now support `channel_prefix` option in `cable.yml`
-
-    Avoids channel name collisions when multiple apps use the same Redis server.
-
-    *Chad Ingram*
-
-*   Permit same-origin connections by default.
-
-    Added new option `config.action_cable.allow_same_origin_as_host = false`
-    to disable this behaviour.
-
-    *Dávid Halász*, *Matthew Draper*
-
-*   Prevent race where the client could receive and act upon a
-    subscription confirmation before the channel's `subscribed` method
-    completed.
-
-    Fixes #25381.
-
-    *Vladimir Dementyev*
-
-*   Buffer now writes to WebSocket connections, to avoid blocking threads
-    that could be doing more useful things.
-
-    *Matthew Draper*, *Tinco Andringa*
-
-*   Protect against concurrent writes to a WebSocket connection from
-    multiple threads; the underlying OS write is not always threadsafe.
-
-    *Tinco Andringa*
-
-*   Add `ActiveSupport::Notifications` hook to `Broadcaster#broadcast`.
-
-    *Matthew Wear*
-
-*   Close hijacked socket when connection is shut down.
-
-    Fixes #25613.
-
-    *Tinco Andringa*
