Where is latest B1 firmware?

Just got a B1 that shipped with firmware 8.3.something. Looking for the 8.4 branch and it does not seem to be on the Peplink download site.

There is a “Balance One” in the Balance section but I dont think that’s the B1 as it has 3 hardware generations.

There is an X section, but no B section.

I don’t see it either. If one types in “one” as @mystery suggested, one sees the FW for the Balance One and B alance One Cores – which are different animals.
Of course, one can always update the FW on-line via System → Firmware.

FYI: The B1 was able to self-update to firmware version 8.4.1
