Netflix released a major update today. Version 7.0 has been optmized for the iPhone 6 and iPhone 6 Plus. This means it takes full advantage of those big displays, allowing you to see more content, without scrolling. Also on the changelog is support for iOS 8 and Chromecast improvements. If you went big with this last iPhone release, this app offers some clear advantages for iPhone 6 Plus owners.
On the iPhone 6 Plus, the Netflix app offers 1080p video. Not too shabby.
Netflix is available as a free update from the App Store.
