As part of its big product event today, Apple is dropping a handful of significant updates to its platforms. The final versions of iOS 9.3, tvOS 9.2, and WatchOS 2.2 will all be available to download today for all supported devices. Apple began beta testing the updates back in January.

For you early adopters, all of these are available right now. Personally, there’s nothing crucial waiting for me so I’ll wait a few days before I update.
