Rockstar Games has released patches today for Grand Theft Auto IV for both the PlayStation 3 and Xbox 360 versions of the game. These patches fix the issues they have identified for each system, specifically multiplayer connectivity issues including freezes during certain modes, continuation when players leave matches, and bugs within races and race lobbies.
You'll be prompted to download the patch next time you're signed into Xbox Live or the PSN and start up GTA IV.

Changed countdown timer in lobby so that it no longer resets when new players join a game.
About time, because that always ticked me off.
Changed the kick option so that kicked players are no longer brought back to single player.
I'm glad they fixed that problem, it always messes up my wireless ethernet connection.
