The document discusses the new features introduced in iOS 4, including multitasking, local notifications, iAd, Game Center, and new frameworks and APIs. It focuses on multitasking, explaining how apps can run in the background to perform tasks, play audio, use location services and more. It provides details on the app lifecycle and how apps should handle transitions between active, inactive and background states to be efficient and prevent termination.
