Well i've posted the changelog on the main topic.
the 7.8 is stable with better temperature handling, usb print are stable, even doing something else on the PC.
All is functionnal is a good to go.
I will post my setting for Makerware print , i got a pretty good result now.
My next hardware mod will be a more thicker glass bed, because the one in the package is too thin, and so doens't present a good level on the whole surface.
the Z probe need to be shimmed, if not the level spring are too much compressed and bend the heated bed.
