iOS 9.1 Update
Apple didn't confirm an iOS 9.1 release on stage but it looks like it will accompany the iPad Pro to shelves later this year. The iPad Pro release date is confirmed for November.
iOS 9.1 will reportedly focus on enhancements for the new 12-inch iPad Pro though we also expect it to come with fixes and enhancements for Apple's other devices.
The iOS 9.1 beta reveals several key features including support for Live Photos, Apple's new Apple Pencil, and 3D Touch APIs.
