the graphical A was repurposed from MechCommander for the new HBS game
CGL started using the logo on the Combat Manuals in 2015-16. It has also appeared on First and Second Succession Wars, the two Spotlight On PDFs, and the aforementioned BMM and TRO: Succession Wars. IntOps and CampOps were the last print products to feature the old logo. Touring the Stars: Iron Land, Old Kentucky, Mizar, and Wynn's Roost from 2017 still used the old logo as well.
I assume all CGL-published materials going forward will feature the new look
