If you were wondering why today's new system update for the Xbox 360 console was relatively large (90MB) but didn't seem to make any significant changes to the operating system's appearance, it's because there weren't any.
Xbox community figurehead Larry "Major Nelson" Hyrb has explained in a blog post
that the update's primary consumer feature is the addition of voice search support for Australian and New Zealand Kinect users.
So presumably, your Xbox console should now be able to process colloquial phrases such as "Oi! Xbox, gis me foxtel ya bum" and "Ay Icksbox, load the most choice game in my tele bro".
According to Major Nelson, the update also contains "Behind the scenes foundational improvement that will not be visually noticeable, but will help enable an easy update this Fall."
As always, the system update can be obtained automatically by connecting to Xbox Live on your console, or download for a manual disc or USB install from xbox.com/UPDATE
