The latest mandatory Xbox Live update most notably adds voice support for Kiwis and Aussies.
All else in the update appears to be background improvements and preparation for other services.
Microsoft has acknowledged that the update may cause issues with Datel controllers and has proposed a fix.
Complaints that the update removes Twitter and Facebook from the social hub, making them accessible only via the Marketplace are yet to be addressed.
Two other Xbox users have stated that following their update, their Xbox no longer reads discs.
