Way early this morning, Major Nelson dropped us a note on the latest update for the Xbox 360.

This update addresses interruption issues that some Xbox LIVE users may have experienced when playing a limited number of Xbox 360 games.

Signing in within the next couple hours, you should be prompted with an update, but if not, you may have to wait for a little while.  There is no word on what games this update was for nor does the update add any new functionality to the 360.
