CoD4:MW Updates List?

Is there anywhere to find a list of what updates have fixed/changed what items for Call of Duty 4? I know the most recent one cut firing rate on all the single-shot fire weapons, but I'm curious what previous iterations have done. Sometimes it's hard to tell, lol. I googled it and came up with nothing.

I feel your pain, lol. The G3 is on the verge of being dead to me now. I've had an itchy trigger finger since playing Virtua Cop on the Sega Saturn, lol.
