Over 3 months after being unveiled at WWDC 2015, the ninth major iteration of iOS has been released to the public today.
After multiple developer and public beta releases, the Golden Master of iOS 9 was seeded after Apple's 'Hey Siri' event last Wednesday. Today the final version of iOS 9 has been released to the public in all its glory.
iOS 9 builds on the user interface introduced with iOS 7 and on the features introduced last year with iOS 8. New features include a new proactive assistant, a new Siri design, a new News app, a new Wallet app, a low power mode and much more. iPad productivity is also a high focal point with new multitasking features such as picture in picture video and split view on iPad Air 2 and iPad Mini 4. In addition to new features iOS 9 also adds multiple under the hood performance upgrades, with less bugs and a claimed 1 hour extra battery life. iOS 9 is also more storage efficient, requiring just 1.5GB to install over the 4.8GB required for iOS 8, preventing many users from upgrading.
The next version, iOS 9.1 is currently in beta testing and is expected to be released alongside the iPad Pro in November.
iOS 9 can be downloaded today via iTunes or in the Software Update section of settings wirelessly. It is available for iPhone 4s and onwards, iPad 2 and onwards and iPod Touch 5th Generation and onwards.
On a final note, the initial hours of release will see people flooding Apple's update severs as they try to install the new software. Historically this has prevented smooth installs for people eager to get the new version of iOS immediately. As a result it might be best to hold off and wait a few hours or keep trying if your install runs into issues; and of course remember to back up your device with iTunes or iCloud before the update!
