Microsoft has already started to roll out the preview of the April update coming for the Xbox One. This preview is expected to run a bit longer than the previous update for the March update.

As such, Microsoft says that the following changes will not all be available in the first update preview and will be added over time prior to the update leaving the testing phase.
What’s new in this release?
  • Game and app saves and updates. A game save progress bar will show you the status of your game saves. You will also be able to easily tell what games and apps are being updated or have been updated recently.
  • Friends improvements. Notifications will be added to see when favorites and friends sign in to Xbox Live. This actually was one of the most frequently requested features from the first preview wave and we made it a priority to include it in the April update. Also, friends who are in multiplayer will be identified in the friends list. We’ll also add the ability to view friends’ most popular apps.
  • Blu-ray 50 Hz video output support for content recorded at 50 Hz will resolve video playback issues some Xbox Live members in Europe are experiencing.
  • Kinect voice and motion improvements will continue to fine tune the quality and reliability of Xbox One commands.
  • Improved GameDVR video quality through compression algorithm improvements.
  • Updates to Xbox One device management to address issues controlling TVs, set top boxes, and receivers that our customers have reported.
  • New audio settings to tune how much volume is lowered when Kinect is used in communications.

For those already in the preview program, you can find out more on the Xbox forums.
