iOS 9.3 is coming in the Spring and will introduce Night Shift as well as a number of other new features.
Apple TV iOS 7 Beta Adds iTunes Radio and Conference Room Display Mode
Users of the Apple TV beta have discovered at least two new features inside. AppleInsider notes that Apple built an iTunes Radio client for the Apple TV -- something that Eddy Cue mentioned during the WWDC Keynote and that Apple has promoted to potential iTunes Radio advertisers -- with in-line video advertisements.
Apple has also added a 'Conference Room Mode' for use in business and academic settings that displays simple instructions for connecting to a Wi-Fi network and sending data from both a Mac or iOS device.
The final version of the Apple TV Beta software should be released alongside iOS 7 in the fall.
