Hi, in current luatex snapshot (LuaTeX, Version snapshot-0.30.0-2008093012, ConTeXt ver: 2008.10.03 23:45) hz seems to be broken (unless I made a typo here): \definefontfeature[hz][default] [protrusion=pure,expansion=quality,mode=node,script=latn] \usetypescript[postscript] \definetypeface[postscript][rm][serif][times][default][features=hz] \setupbodyfont[postscript,10pt] \setupinterlinespace[line=12pt] \setupalign[line,block,hanging,hz] \starttext \showframe \input tufte \stoptext Steffen
