Xbox Preview Program Now Open to All
Xbox's Preview Program that allows invited users to preview updates, features, and apps has now been rebranded to Xbox Insider Program and is available to anyone.
To gain access to the new program all you have to do is opt in for it, no invitation required. The Preview Dashboard, now called Insider Hub, has been rebuilt from the ground up based on feedback from previous users. The UI has been rearranged a bit, the dashboard now offers notifications that are catered to useful information to Insider members.
The only thing that won't be available to Insider hubs are new system overhauls. These will continue to be reserved for invited members only. However, minor updates and new apps will be introduced to Insider members.
