iOS 9.3 is coming in the Spring and will introduce Night Shift as well as a number of other new features.
Apple to Offer Live Video Stream of WWDC Keynote on June 2
Users will need Safari on Mac/iOS or QuickTime 7 on Windows in order to watch the stream, and Apple will also be making the stream available through a channel on Apple TV.
A number of announcements are expected at the WWDC keynote, with OS X 10.10 and iOS 8 expected to be the major focus of the event. OS X 10.10 in particular will reportedly be receiving the most attention as it will be receiving a facelift somewhat similar to that seen with iOS 7 last year. iOS 8 is said to be a more modest update, although there will undoubtedly be plenty of changes and additions relevant to users and developers alike.
Hardware announcements are a bit less certain, with two highly anticipated and long-rumored products in the iWatch and a revamped Apple TV unlikely to make their appearances at the event. Apple's rumored Retina MacBook Air may also not be ready, but the company could slip in some other announcements such as updates to the MacBook Pro or outdated Mac mini, or perhaps a low-priced iMac.
