is this version 12.1.6 MP1 or MP2

I downloaded the following file from fileconnect

Symantec_Endpoint_Protection_12.1.6_MP2_Full_Installation_EN

SEPM installs version 12.1.6465.6200 which i understand is MP2

But client installation packages for windows are 12.1.6318.6100 (MP1)

is somting wrong with the package or is there not yet a MP2 client package

thanks
