rails--rails/actioncable/CHANGELOG.md

• Removed deprecated evented redis adapter.

  Rafael Mendonça França

• Support redis-rb 4.0.

  Jeremy Daer

• Hash long stream identifiers when using PostgreSQL adapter.

  PostgreSQL has a limit on identifiers length (63 chars, docs). Provided fix minifies identifiers longer than 63 chars by hashing them with SHA1.

  Fixes #28751.

  Vladimir Dementyev

• Action Cable's redis adapter allows for other common redis-rb options (host, port, db, password) in cable.yml.

  Previously, it accepts only a redis:// url as an option. While we can add all of these options to the url itself, it is not explicitly documented. This alternative setup is shown as the first example in the Redis rubygem, which makes this set of options as sensible as using just the url.
