YouTube on Tuesday rolled out a significant update for its app on Windows Phone 8, completely redesigning the experience to take advantage of the platform's minimalist appearance. Microsoft said the app just went live, so you should get a notification soon; if not, you can manually update by going directly to the app's page.

When you do pick up the new YouTube, you'll see glut of new features, including the ability to share videos through email, text and social networks, and a neat option that allows you to play a video in the background, even when your screen is locked. Additionally, users can pin videos, playlists and channels to their Start Screen (the tile will show either the latest video or the most popular one), and an all-new playlist design.

If you have kids, the update support YouTube's Safety Mode, which parents can take advantage of through Windows Phone 8's Kid's Corner. There's plenty to digest here; the update is pretty robust and adds a lot of great little flourishes for a better mobile YouTube experience. If you're running Windows Phone 7.5, an updated YouTube app is expected to hit in a few weeks.
