[hpsdr] Metis ver 1.6 vs 1.7

[wbr at verizon.net]

I've been trying to find what the difference is
between the last two releases of the METIS
Firmware.

Can someone tell what was changed
between version 1.6 and 1.7

Both work for me,  but the difference
must be very subtle.

Thanks,  73,  Bill,  wf4r
