The new 2.19 version of the app allows U.S. users who have Windows Phone 8.1 installed on their devices can now begin calls just by using Cortana. Microsoft says, "Now you can start Skype video and audio calls by simply asking Cortana something like "Skype get Lara Kingwell on the screen". In addition the new version lets 8.1 users swipe down to see any emails, texts and Skype updates in the Action Center feature. It also lets users edit their last sent message, which might come in handy for folks who type something up quickly. http://www.windowsphone.com/s?appId=c3f8e570-68b3-4d6a-bdbb-c0a
