Thanks, Henri.
The mwe seems to work without specifying the font, but that may just be a
deceptive triumph of bad
form.
I have a number of fonts in my document in which I would like \textfraction to
work. Is there are
global way to prepare them or must I do it one by one?
You cannot prepare the font for this by yourself (unless you are a font
designer). The font needs
to have the "frac" feature present. Your macro \textfraction{1/2} simply
typesets 1/2 with the frac
feature enabled. You can find out if your font has this feature using the tool
otfinfo, e.g.
in context the font script can give all kind of info
mtxrun --script font --list --list --file --pattern=dejavu* --info
$ otfinfo -f FiraSans-Regular.otf

Adding
\definefontfeature[fraction][frac=yes]
\definehighlight[textfraction][style={\feature[+][fraction]}]
fixes the problem in the sample just sent.
This, and the font has to have the corresponding feature present.
Sorry for the misfire.

Has there been a change to \textfraction?
Try
1\textfraction{1/2}.
I get
1 /1/2
with ConTeXt ver: 2017.06.30 (and earlier on the wiki)
