The new update largely gets things ready for this year's new Windows 10 dashboard and speedier user-interface.
According to Larry 'Major Nelson' Hryb, the update also fixes some known party chat issues.
Microsoft's new WIndows 10-inspired dashboard will launch alongside Xbox 360 backwards compatibility in November.
The dashboard will place an emphasis on speed and community, and also features Cortana integration.
Microsoft is also planning to introduce an early access scheme to Xbox One, similar to the one found on Steam.
