It's strange... That on the github, where is official excavator place is no 1.3.0a version...
Did you know v1.3.0a list of changes?
Color text :-) and new Dual algorithms: daggerHashimoto\pascal, daggerHashimoto\decred, daggerHashimoto\sia
If this is true then I will say goodbye to Claymore's dual miner. Looking forward to finding out, thanks for the info.
