Apple has announced Sept. 16 as the official release date for iOS 9, the next major update to its mobile operating system. Originally shown in June at the company’s Worldwide Developers Conference and then released into public beta over the summer, iOS 9 will add a number of new features including a more proactive assistant mode for Siri, Transit directions in Apple Maps, a News app for curated news feeds, split-screen multitasking for iPad users, and support for loyalty cards in Passbook, which is being renamed Wallet in light of its new role. The new version will also offer HomeKit support for new devices, as well as accessing HomeKit via iCloud, and support for wireless CarPlay connections. New developer features will also allow for smaller and more efficient iOS applications. The new version is also expected to run more efficiently on older iPhone and iPad models.
