Hi all,

the most recent luatex seems to have problem with extending fonts.
(linux-armhf rev 6378 and 6379, Windows 64 rev 6378)

My example:

\definefontfeature[extend][default][extend=1.4]
\definefontfeature[narrow][default][extend=0.8]
\definefont[one][name:yanonekaffeesatzbold*narrow]
\definefont[two][name:yanonekaffeesatzbold]
\definefont[three][name:yanonekaffeesatzbold*extend]
\starttext
\one Montag, 3. Juli 2017\par
\two Montag, 3. Juli 2017\par
\three Montag, 3. Juli 2017
\stoptext

Is it a bug or am I missing something?

Greetings Lutz
