rails/actioncable/CHANGELOG.md

• ActionCable::Connection::Base now allows intercepting unhandled exceptions with rescue_from before they are logged, which is useful for error reporting tools and other integrations.

  Justin Talbott

• Add ActionCable::Channel#stream_or_reject_for to stream if record is present, otherwise reject the connection

  Atul Bhosale

• Add ActionCable::Channel#stop_stream_from and #stop_stream_for to unsubscribe from a specific stream.

• Add PostgreSQL subscription connection identificator.

  Now you can distinguish Action Cable PostgreSQL subscription connections among others. Also, you can set custom id in cable.yml configuration.

  SELECT application_name FROM pg_stat_activity;
  /*
      application_name
  ------------------------
  psql
  ActionCable-PID-42
  (2 rows)
  */
