Hm, has something change in the way a font feature should be implemented? This used to work: \definefontfeature[smallcaps][default][script=latn,smcp=yes] \starttypescript [sans] [seravek] [name] \definefontsynonym [Seravek-Roman] [file:Seravek-Regular] [features=default] \stoptypescript \starttypescript [sans] [seravek] \definefontsynonym [Sans] [Seravek-Roman] [features=default] \definefontsynonym [SansRegularCaps] [Sans] [ features=smallcaps] \stoptypescript \starttypescript [Seravek] \definetypeface [Seravek] [ss] [sans][seravek][default] \definetypeface [Seravek] [mm] [math][palatino][default] \stoptypescript \usetypescript[Seravek] \setupbodyfont[Seravek,ss,12pt] \starttext This is \fontname\font. {\sc This is \fontname\font.} \stoptext I get no smallcaps. If I add \def\sc{\addff{smcp} I get still no smallcaps. Willi
