Hi all (Hans, Taco...), thre appears to be a problem with font-syn.lua in the latest release. First, there's a typo in l. 291. I think if not filename and not reloaded and fonts.name.autoreload then should be if not filename and not reloaded and fonts.names.autoreload then But even after correcting that, I still get errors when compiling something with Greek in it: This went wrong: ...al/texlive/texmf-local/tex/context/base/font- syn.lua:296: attempt to index local 'name' (a nil value) report >> fontnames: 0 system files identified, 0 hash entries added, runtime 0.000024 seconds. <to be read again> \relax \xxdododefinefont ...tspec {#4}\newfontidentifier \let \localrelativefontsiz... \fontstrategy ...me \fontclass #2#3#4#5\endcsname \tryingfontfalse \fi <inserted text> ...yle \fontalternative \fontsize \fi \iftryingfont \fontstr... \synchronizefont ...strategy \the \fontstrategies \relax \fi \iftryingfont \... <argument> \getvalue {\@style@ \fontstyle } \edef \fontstyle {\fontstyle }\if... ... l.68 \startgreek ? ! Emergency stop. Any pointers? Thanks! Thomas
