Windows Phone 8.1 has been out as a developer preview for just a little more than a week, but we are already seeing developers updating their apps to support the OS’ new features. Among the many apps being updated is Wikipedia, developed by Rudy Huyn. This app is the closest to an official app from one of the world’s largest resources for information, as it is made by a popular third party developer with Wikipedia themselves approving and endorsing it for the platform. The app now has been updated to include support for Cortana, the new personal voice assistant and one of the major new features of the OS. Once updated, the v2.3 will let you directly search for topics using your voice by giving simple commands to Cortana.
