This update includes the latest version of the Unreal Engine 4. Also, a lot of improvements and fixes that were asked by the community are in the game now - for example a request about disabling Motion Blur.
Overall netcode was improved to make it use up less packages, to give you a smoother experience.
Also another balance update has taken place, reducing amount of enemy health on higher difficulties and reducing damage the Butchers deal while increasing spawn rate, giving the game a faster, more action oriented pace while keeping overall difficulty intact.
