NO LONGER IN BETA: Back in January, Apple announced that it was debuting four new features for Apple iOS device users in the classroom, timed with the eventual release of iOS 9.3. The features were in beta back then—but no longer. As of March 21, Apple has officially released iOS 9.3, and along with it, the new "Classroom App," improved deployment and management, and a teacher's guide on incorporating the app and other features into the classroom.
