Remember those new Xbox One features Microsoft announced at Gamescom this week? They're available right now -- at least to members who are part of the company's preview program. Major Nelson just announced that Xbox Live users that have access to preview updates will be able to download the new features today. This includes the updated Friends section announced earlier this week as well as SmartGlass TV streaming, the system's new boot to TV mode and the long awaited Media Player app. The announcement also revealed a host of previously unannounced updates, including tweaks to the Party app and Xbox One's GameDVR.
