rails/actioncable/CHANGELOG.md

• Added ActionCable::SubscriptionAdapter::EventedRedis.em_redis_connector/redis_connector and ActionCable::SubscriptionAdapter::Redis.redis_connector factory methods for redis connections, so you can overwrite with your own initializers. This is used when you want to use different-than-standard Redis adapters, like for Makara distributed Redis.
