Apple sent an email to developers today, asking that they finalize their apps for submission to the App Store ahead of the public release of iOS 7 next week. The email specifically mentions several new iOS 7 features as well as the new APIs that take advantage of iPhone 5s features like the M7 motion coprocessor.

Apple is asking developers to test their apps for iOS 7 compatibility, with requirements that apps be optimized for the Retina display and for the 4-inch display introduced with the iPhone 5.iPhone 5s is powered by Apple's next generation A7 chip, making it the world's first smartphone with 64-bit desktop-class architecture for blazing fast performance in the palm of your hand. The iOS kernel, libraries, and drivers now take advantage of 64-bit, delivering up to 2x faster CPU and graphics performance for your apps and games. And it's easy to build and run your apps in 64-bit because Xcode automatically builds your apps into binaries that will run on both 32-bit and 64-bit devices.
iOS 7 is scheduled for public release next Wednesday, September 18.
