The April update includes:
Party chat improvements – Additional icons and notifications within the party chat experience to help you understand your connection and microphone status. The party app will help you get your microphone enabled and show you when privacy settings or networking issues are blocking communication with particular party members.
• Game hub links – You’ll see activity feed items when any of your friends follow a game, and you’ll also be able to get back to a game’s hub from activity feed posts related to the game – including feed items about the game’s achievements, game clips and screenshots.
• Achievement notifications – With this update, you’ll also see the achievement’s description in the notification so you know what you did to earn this achievement without having to open the achievements app.
• What’s On – The What’s On area is now available for Xbox One users in the U.S., Canada, and the UK. In it, you’ll find links to popular videos, games, movies, TV shows, game broadcasts and clips, along with Trending TV shows if you have configured OneGuide for your Xbox One console
