Apple announced some new features for its Apple TV set-top box during WWDC today. The company is bringing live sports and news to the TV app, along with full Dolby Atmos support coming to the Apple TV 4K.

Apple TV 4K is now the first (and only) streaming device to support both Dolby Atmos and Dolby Vision. iTunes Movies will start offering Dolby Atmos this fall, and just like when Apple started offering 4K videos, any movies you already own will get updated to Atmos for free.
