Passenger author here. Phusion is excited about the Rails 5.0 release! Rails is one of the most productive web frameworks out there, and 5.0 just makes it even better.
We have release various Passenger updates to ensure that Passenger plays well with Rails 5, Action Cable etc:
However we found a bug in Action Cable yesterday which may cause issues with app servers such as Passenger and Puma. Unfortunately the fix didn't make it into 1.0. I recommend anybody who uses Action Cable to apply our patch locally for now: https://github.com/rails/rails/pull/25615
