The Call of Duty: Advanced Warfare patch promised earlier this week has been deployed on Play Station 4 and Xbox One.
You can read the entire patch notes in full over on the official forums, as the list is rather long.

The PC, PS3 and Xbox 360 updates will be made available "soon".
The update is the "biggest title update yet" and includes balancing tweaks, fixes, improvements for emblems, Player Lobby improvements, a new way to view the Armory, map exploit fixes, spawn improvements, connectivity optimizations, anti-cheat improvements, and tons more.
