Hi, if there any changes in the interface for using symbols?
I tried today the example from Aditya's Blog but it shows no symbols:

\definetypeface[mainfont][rm][specserif][Linux Libertine O][default]
\definetypeface[mainfont][mm][math] [TeX Gyre Pagella Math][default]
\definetypeface[mainfont][tt][mono] [Dejavu Mono][default] [rscale=0.8,
features=none]
\setupbodyfont[mainfont,11pt]
\usesymbols[fontawesome]

\define\FA{\dosingleargument\doFA}
\def\doFA[#1]{\inlinedbox
    {\scale[height=1em]{\symbol[fontawesome][#1]}}}

\starttext
Checked box \FA[check-square-o]
Unchecked box \FA[square-o]
\stoptext
i use luamtetex for archlinux with all luatex modules linked to lmtx folder
