Apple today released iOS 9 to the public, making the download available to all users who have an iPhone 4s or later, iPad 2 or later, 5th-generation iPod touch or later, or any iPad mini. The update can be downloaded through iTunes or over-the-air by going to the Settings app and tapping General --> Software Update.
As with all major software updates, it may take a few minutes for the update to propagate to all users due to high demand. Public beta testers who have the iOS 9 golden master installed will receive the release version of iOS 9 over-the-air as well.
iOS 9 builds on content introduced with iOS 8, bringing subtle design changes, refined features, improved functionality, and performance enhancements. From Apple's release notes:The operating system's biggest focus is on intelligence and proactivity, letting iOS devices learn user habits and act on that information, opening apps before we need them, making recommendations on places we might like, and guiding us through each day with new Siri and search features.
Many built-in apps have been improved, including Notes, Mail, and Maps, wihch has gained Transit directions. Apple Pay has been renamed to Wallet, and for the first time, iOS 9 brings split-screen multitasking features to the iPad.
In addition to these consumer-facing features, iOS 9 introduces significant under-the-hood improvements that will free up storage space and improve battery life. With battery optimizations, iOS devices have an additional hour of battery life, and a new Low Power mode can extend battery even further.
iOS updates take up less space in iOS 9, letting even devices with little storage space upgrade, and many app install sizes are smaller due to a feature called app thinning.
