rails--rails/actioncable/CHANGELOG.md

• 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)
  */

• Subscription confirmations and rejections are now logged at the DEBUG level instead of INFO.
