True, disables 3rd party batteries.
I'd noticed this with 1.1.3 and 3rd party (non-oem) batteries. I haven't installed 1.1.4 yet, and may never install it.
Overall, my 6d seems much fussier and uncooperative about batteries than my 5d2. Even the 6d charger can be a p.i.t.a. to work with, compared with the charger that came with the 5d2.
