If you're a Xbox One Insider, you may be able to download a brand-new update. A Preview alpha build is now available for download for some players who take part in the Insiders Program, which allows players to test out new system and games features before they go live to all other players. Some new features will be available right away, with others rolling out over the next several weeks.

The biggest addition coming for Xbox Insiders is the Next Achievements feature in the guide. Now, those who test new features and games from Xbox One will be able sort a cross-games list of upcoming Achievements. This way, you can easily see which Achievements you're closest to and quickly launch the game to achieve them. You can also sort your Achievements by how rare they are.
