Hi Hans & comp. is there any reason why the latest beta doesn't typeset random glyphs with rand feature as it used to at least a year ago? *.tma and *.tmc files also differ in size. ConTeXt ver: 2011.08.04 00:42 MKIV LuaTeX-0.70.1 \definefontfeature[punk] [mode=node,script=latn,rand=yes,kern=yes,tlig=yes] \starttypescript[serif][punknova] \definefontsynonym[Serif][file:punknova-regular][features=punk] \stoptypescript \starttypescript[punknova] \definetypeface[punknova][rm][serif][punknova][default] \stoptypescript \setupbodyfont[punknova] \starttext \rm \input knuth\par \stoptext BTW, is \installfontfeature deprecated as the font-ini.mkiv says: "installing font features *was* experimental"? Any other way to install font features from *.fea file instead of \installfontfeature[otf][rock] \definefontfeature [myfeature] [mode=node,rock=yes,featurefile=rockfile.fea] Thank you, Jano
