iOS 9.3 is coming in the Spring and will introduce Night Shift as well as a number of other new features.
Key iOS Engineering Executive Henri Lamiraux Retires from Apple
He says that he retired from Apple a "couple of weeks" ago, following the release of iOS 7.0.3. Lamiraux decided a "little while ago" that iOS 7 would be his last release.
Sources within Apple's iOS division say Lamiraux is respected and he was in charge of developing the applications that come with iOS. The executive also led feature-implementation across the operating system, and he managed both bug-fixing processes and feature distribution to consumers. He also managed the frameworks within the operating system that power features and allow developers to build applications.
Lamiraux joined Apple in 1990, spending ten years as a Mac OS and later OS X software engineer before being promoted into more senior positions. He moved over to iOS in late 2005, more than a year before the original iPhone was shown to the public, and served in several managerial roles, culminating with his being named Vice President of Software Engineering for iOS Apps and Frameworks in September 2009.
