Details on each change can be found in the link above. I really don't like some of the FOB changes. They're seemingly just added in so they can sell you more FOB coins. Things like adding new weapons though is a welcome change.

Infiltrate without leaving a trace!
FOB expansion time reduction now available!
Improvements to on-screen UI elements and point scoring!
