I don't recall explicitly adjusting anything related to hardware error percentages.
Try attaching a screen shot of what you notice was omitted in this build.
Not much has changed recently on the display side.

http://23.108.83.14/images/2Pac-0012.pngIf you are comparing pre 4.10, I wouldn't be able to answer.
There would probably be some notes in GitHub.
Now that I've looked at further, I see that cgminer hasn't included HW % rate; I was confusing it with bfgminer I suppose.
My apologies.
