Apple updated its developer portal on Wednesday with new statistics on its current mobile operating system, iOS 8. Adoption for the system is up to 68 percent across both iPhones and iPads, up eight percent from approximately six weeks ago. As would be expected, older versions thus continue a decline in popularity, with iOS 7 losing six percentage points and dropping to 29 percent, while iOS 6 and all earlier versions are essentially down to just devices that can not be upgraded beyond that point, holding around four percent share (a drop of one percent from the last report).
