iOS 9.3 is coming in the Spring and will introduce Night Shift as well as a number of other new features.
Apple Tweaks Website Design with Darker Navigation and Animations
Apple made some slight design changes to their website tonight, with a new dark navigation bar, as well as spring loaded and slide-in animations for products. The new design resulted in several hours of downtime for the Apple online store.
Some last minute part numbers had suggested the long awaited white iPhone may have been making an appearance, but that was not the case. The online store has adopted the new darker navigation bar, but there are no signs of new products.
