Do any of you have examples of apps that do a good job of highlighting new features in a contextual manner? Think adding a new feature to an app that can only be accessed from certain places (navigation menus, popups, etc.). Ideally I'd like to call these out when the user navigates to one of those places vs. a standard 'What's New in Version X.X.X' popup you see after upgrading an app. Also, bonus points if you have examples that are interactive vs. simply showing the user what they can do. I tried a little searching, but it's a tricky thing to search for. Any help/app examples/resources would be great. Thanks!
