[hpsdr] Firmware Version Confusion

[Mike F]

I am running Psdr 2.2.3,  When I look under the HPSDR setup tab I see 
that the firmware versions I installed in early November are:

Metis 6.7
Mercury 6.7
Pennylane 1.5

Neither Metis or Mercury have revisions anywhere near as high as 6.7 on 
the download page.

I ran into this problem when trying to verify that I had the latest 
firmware.  I suspect that these came from (maybe) W5WC's or K5SO's site. 
  Is there an easy way to determine which firmware versions are required 
for each app configuration (ie. 2.2.3, Ghpsdr3, Kiss, multiple mercury, 
multiple receiver, etc.).

Thanks
