How to get your hands on it all:
Starting at 3:01AM ET (12:01AM PT) staged updates will roll out to Xbox One users all over the world. There are two ways to get the update:
Instant-On Power ModeTurn on this feature via Settings > Power & Startup. Your Xbox One will automatically download the update when your console is in Connected Standby Mode. Updates will be released by time zone, so this seems to be the best option to get the update as soon as its out so it’s available later Thursday.

When you’re ready to download it, or check in on if your time zone has received the update, go to Settings > System > Update Now.
