Apple has announced during its March 2016 event that tvOS 9.2 will be made available today, March 21, and it will bring a number of new features to the Apple TV. With this update, you'll now have folders for your apps, so you can sort them the way you want, just like on your iPhone or iPad. Additionally, you'll be able to dictate text and passwords, as well as use Siri search in more apps. Some of those apps include CBS, History and A&E.
The Apple TV is gaining iCloud photo library support with Live Photos, so you'll be able to play your photos and videos on the big screen with ease. As noted above, the update will begin rolling out today, March 21, as a free update to the Apple TV.
