Earlier this week, Apple released the second iteration of the minor update to watchOS, watchOS 2.2. watchOS 2.2 comes alongside tvOS 9.2, iOS 9.3, and Mac OS X 10.11.4 El Capitan.
All of these updates are fairly major in comparison with the other minor updates that Apple has released since the major updates (iOS 9, watchOS 2, etc.). iOS 9.3 has a number of new features, such as Night Shift and TouchID support for Notes. Mac OS X 10.11.4 El Capitan supports some of the features that come with iOS 9.3. tvOS 9.2 supports Bluetooth keyboards.
When the original watchOS 2.2 bneta was released, the only actual new feature was the ability to pair multiple Apple Watches with a single iPhone. watchOS 2.2 beta 2 actually has a new feature, which is a new Maps app. Check it out.
