v11.8:
Thanks again.
Temps via RDC and new option -showdiff work fine.

Just a note: in readme file you forgot to indicate value of the new option -showdiff
1 (missing 1)
You are correct, thanks, I updated OP:
-showdiff use "-showdiff 1" to show difficulty for every ETH share and to display maximal found share difficulty when you press "s" key. Default value is "0".
