Here's what's new:
FastStart Enabled for Select Titles
Announced back at E3 2018, FastStart allows you to jump into your games twice as fast and play after downloading just a fraction of it. FastStart works by identifying which files are needed to begin playing and prioritizes the download of those files first, enabling you to quickly jump into full-fidelity gameplay while the remainder of your title downloads in the background. Find the FastStart-enabled title you want to play in our catalog, hit 'Download' and your console will take care of the rest. What's more, it's now enabled for select English language titles in the Xbox Game Pass catalog, and will expand to more games in more languages over time.
Group Your Games and Apps
The update introduces a new enhancement to Pins, which Microsoft calls "Groups." With Groups, you can create multiple collections of content made up of anything from within My Games & Apps. You can also assign custom names to each Group, organize and order them, and add individual Groups to Home. Groups will appear across My Games & Apps, Home and Guide, so you'll be able to access your Groups at a moment's notice. Groups are tied to your Xbox Live account, so they will automatically sync across multiple Xbox One consoles.
Search Improvements on Xbox One
Searching for content is now easier. Now pressing the Y button anywhere in the dashboard will bring up the search dialog, allowing you to easily launch your content, sift through Settings, or find products in the Store. This process is found in many apps, but now you can do it anywhere within the dashboard.
Mixer Share Controller Improvements
Microsoft has made it easier to use Share Controller on the web. First, full mouse and keyboard support has been enabled for PC users, along with Share Controller Key Bindings.
Second, Microsoft has added multi-touch support for touch-enabled devices. This allows multiple controls to be used at the same time. For example, you can control the joystick and press A at the same time on your touch laptop.
And lastly, a per-channel leaderboard that spotlights viewers who have contributed to a streamer's channel the most during a Share Controller session has been added.
Full Screen Broadcasting on Mixer
Mixer streamers can now go full screen with their webcam while broadcasting. You can switch to full screen webcam broadcasting at any time you want. While in this mode game audio is muted, making it perfect for talking to your audience while switching from game to game or setting up before you start playing. You can even do all IRL broadcasts.
Console broadcasting quality and stability improvements
Microsoft has also made a number of changes and fixes to improve overall broadcast video quality. You will now experience improved performance when broadcasting bandwidth-heavy multiplayer.
