Ars Technica:

Apple officially announced iOS 9 at WWDC in June, and adventurous users could start playing with the public beta in July, but today the company announced a public release date for the finished version of the operating system: Wednesday, September 16.

The software update will arrive a couple of days ahead of Apple’s latest iPhones, which was to be expected given Apple’s past behavior. An unexpected benefit of this release is that it won’t drop support for any device currently running iOS 8—iOS 9.0 will run on iPhones as old as 2011’s 4S, iPads as old as 2011’s iPad 2 or 2012’s iPad Mini, and both the fifth- and sixth-generation iPod Touch.

I’m really looking forward to iOS 9 and the new features, especially split screen. Apple also quietly announced the release date for OS X 10.11 El Capitan – September 30th.
