The update also eliminates duplicate headers in the video list, prevents the navigation bar in Events from disappearing and corrects the problem that led to blurry text in session details. Version information has been added to improve bug reports. The app is available for free from the Apple App Store.
Like the app provided every year by Google for Google I/O, the WWDC app is made for both those attending and those watching at home. Streaming video allows registered Apple developers to view key sessions at home while those attending will be helped out by maps of the Moscone Center and other features.
