It is worth noting, you'll need to log back in after installing the update. Doing an iCloud restore of your iPhone has also triggered a logout in the past. Basically, never have push notification as your only notification method. Also a reason to consider sticking to manual app updating.

The app is much faster, and much better looking, but I can't help but think functionality has taken a backseat. While before it would tell me not only that I was on call, but what on call schedule I was currently on call for on the same screen. Many people use multiple schedules to set up a primary and secondary on call for a service. Now, it just tells me that I'm on call.. it takes a lot of digging in the app to see which on call schedule.
