In Steam News there was an announcement for a new patch for Left 4 Dead 2 with a list of many different updates. I have provided a link for you here as well as listed some key points made.

Updates to Left 4 Dead 2 have been released. The updates will be applied automatically when your Steam client is restarted. These and all previous fixes will be coming to the 360 later this month.

I am hoping that before the new year when the influx of gamers that receive this game for Christmas are rewarded with this patch.
