Here’s the complete list of patch notes:

   Fixed one of the most frequently occurring client crashes
   Fixed broken collision on containers with open doors. The bug previously made grenades bounce back even though the doors were open.
   Fixed a bug in Defuse mode where defenders could win the round by killing all the attackers without disarming the bomb, if the bomb was disarmed in the previous round.
   Miscellaneous stability fixes further reducing the number of client crashes
   Fixed side gunner jitter when aiming in attack boats & transport helicopters
   Fixed some instances of frame rate drops when shooting at large Levolution objects after they have been destroyed (like the radar dish on Rogue Transmission)
   Fixed broken aiming for passengers on the China Rising dirt bike
   Fixed a bug where the sound when capturing a flag was not playing correctly
   Removed a bug that would double save during MP round transition and SP level transition. This fix will reduce the occurrence of corrupted save files.

I died dozens of times to this stupid bug.. glad it's fixed.

If the would only fix the jittering when some one revives you. Very annoying
