QuickType, Family Sharing, iCloud Drive and the Health app expanded the system. Messages gained voice messages and more group controls. Extensions enabled third-party keyboards. Individual features depended on the device, language and region.
The update was announced for iPhone 4s and later models in Apple's list, fifth-generation iPod touch, iPad 2 and later compatible models, and the iPad mini family. It does not include iPhone 4. Support for iOS 8 does not mean support for every feature.

iOS 8.1 added Apple Pay for iPhone 6 and 6 Plus in the United States and iCloud Photo Library in beta. iOS 8.4 added Apple Music. These are later revisions, not features fully available in iOS 8.0.
