iOS 9 is just about ready for consumers and will head to their devices in a week. Devs will be moving their attention to iOS 9.1, which just became available for them in beta form.
The update is of special interest as it brings support for 12.9″ screens and the iPad Pro will be the hot new tablet on the market and apps will need to be ready for it when it comes out in November. The 9.1 update also optimizes split-screen app usage and picture-in-picture video playback, which will be a big part of the iPad Pro experience.
Same goes for Apple Pencil support, 3D Touch and Live Photos. Oh, and there are new emojis too.
