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 also has published a guide for developers on the new features built into the iPhone 5s, including the 64-bit A7 processor, OpenGL ES 3, the M7 motion coprocessor and the Core Motion APIs.
