Those who have signed up for Apple’s beta testing program should be getting an over-the-air update for the iOS 11 beta after installing the proper certificate on an iOS device. New additions include a revamped control center, updated design elements, drag and drop, an iPad dock, Siri improvements, peer-to-peer Apple Pay, and a Do Not Disturb driving mode. iOS 11 brings subtle design changes to the operating system, including a new Lock screen experience and a customizable, redesigned Control Center. Siri is smarter, has a more natural voice, and can do more, Messages features person-to-person Apple Pay, Notes has searchable handwriting and document scanning, and Music now lets you share playlists with your friends. A new Files app improves file management on iOS devices, and for the iPad in particular, there's a new Dock, an App Switcher, and support for Drag and Drop, all of which vastly improves multitasking on the device.
