Presumably, the update adds support for at least some of the upcoming 9000 series CPUs from Intel:
Intel has already leaked their upcoming 9000 series of processors, which offers up to six processing cores with their i5 series branding, lacking any i7 listings under the code name "Coffee Lake (6+2)" with the six identifying core count while the 2 signifies the unit's number of graphical processing units.Via: Overclock3D
