Rails 5.1.0 (April 27, 2017)

• ActionCable socket errors are now logged to the console

  Previously any socket errors were ignored and this made it hard to diagnose socket issues (e.g. as discussed in #28362).

  Edward Poot

• 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
