Today's Hey Siri event is over, and Apple is wasting no time in releasing the latest builds of iOS for developers. In addition to the Gold Master for iOS 9, the company is now seeding iOS 9.1 to developers.
Update: Read the Apple iOS 9 review.
iOS 9, which will officially launch on September 16th, promises a lot of upgrades that will make iPhones and iPads faster and more efficient. Apple Pay, Notes, and Maps, among others, are all getting significant upgrades, and Apple's new News app will provide mobile-optimized articles from a bevy of outlets. Siri is also getting a lot smarter in the release. While it isn't yet clear what 9.1 will bring to the platform, it's easy to guess that it will add bug fixes and improvements.
