DICE pushed out both a new client patch and a server patch today on Dec 9. Here are the patch notes for the client patch. And here are the patch notes for the server update R15. Anyway I will quote both patch notes here.
Client Update Dec 9:
-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.
Server Update R15:
-Various server side crash fixes, including the top seen crashes on R14
-Activated the reservedSlotsList.aggressiveJoin command that enables VIP players and server administrators directly joining full servers
-Client patch compatibility to make servers compatible with the Dec 09 client update
