The Xbox 360 received a system update today, which not only brings new features but also increases the Cloud storage limit.
Starting today, the Xbox 360's cloud storage limit, which was previously 512MB, has been increased to 2GB. This will allow players to use their Cloud storage to save even more game saves, which will also be very helpful to transfer them to Xbox One to continue playing your Xbox 360 games via Xbox One's backwards compatibility.
This update also introduces an Activity Feed, allowing users to like, comment and share your friend's activities, post new messages, watch game clips, view screenshots, and more. Other new features include the ability to see what your friends are playing on Xbox One and Windows 10, access your movie and TV collection from Microsoft Movies & TV and your Music in Groove Music, reedem codes from messages, and check your Microsoft account balance while looking at the details of a game or when browsing the marketplace.
