Not so long after the 1.6 patch, Infinity Ward have released the official 1.7 patch. It's not as much of patch compared to 1.6 but it fixes a couple of known issues...

Fixed an exploit that allowed players to access certain console dvars during multi-player matches.
Fixed a crash that could occur when a Chinatown Sabotage match would go into over-time.
Fixed a bug where the MP icons (Bomb, Defend, Capture, etc) were always showing up as English regardless of the install language
