How can I change the arrowstyle etc.? The code below used to work pre v5.0. I've searched around the manual and the net a bit, but didn't really find something useful. Is it even possible in v5.1?
MnWE:
\documentclass{scrartcl}
\usepackage{chemmacros}
\usechemmodule{all}
\chemsetup[chemformula]{arrow-style = {>=stealth',line cap=round,thick}}
\RenewChemArrow{->}{\draw[chemarrow,->] (cf_arrow_start) -- (cf_arrow_end) ;}
\chemsetup[chemformula]{font-spec = {[Numbers={Proportional,Lining}]MinionPro}}
