At the March 21 special event, alongside the various hardware announcements, Apple also released public versions of updates for iOS and tvOS. Both new releases bring some new features along with them, but are focused primarily on small "fit and finish" issues as well as improving security, speed, and fixing bugs. One feature shared between the new iOS 9.3 and the forthcoming OS X 10.11.4 is the new ability to create and encrypt individual notes in the Notes app using a passcode and Touch ID.
