Turris OS 4.0 is released for testing (HBT)

I have a strange problem after the b11 installation with my MOX (modules P-A-G-B), but don’t know if it has to do with the update as I directly upgraded from b1 just before:
Foris/OpenWRT keeps detecting 3 WiFi-cards whereas I only have two installed (see also here):
