The feature changes that you will see include making the globe heat map visible on the GamePad screen while in the multiplayer menu and tweaks to address the accuracy of theatre replays following weapon use in ADS.

Beyond that, the patch includes a number of fixes that address some Wii U specific issues as well as a number of issues that are not specific to the Wii U version. A good job was done outlining these fixes and tweaks in the patch notes in the community at callofduty.com .
