No changes whatsoever. The Arrivals facility is really an extension of the IFL with 6 or so shower suites. A door at the back of the UC leads there during opening times in the morning. It's great for connecting pax, however I'm not sure how pax who terminate in ORD would go about re-entering security after immigration.
Don't worry about the web site... since the merger there hasn't been a decent/proper section about Arrivals and First class lounges.
