Hi all,
I can't get Kerning working with Noto Serif.
My minimal file is:

\definefontfeature[oldstylenumber][onum=yes]
\definefont[testnoto][file:NotoSerif-Regular*default at 12pt]
\starttext
Line 1: {VAVAVAVAVAVA 12345}\par
Line 2: {\setff{oldstylenumber}VAVAVAVAVAVA 12345}\par
Line 3: {\addff{oldstylenumber}VAVAVAVAVAVA 12345}\par
\testnoto
Line 4: {VAVAVAVAVAVA 12345}\par
Line 5: {\setff{oldstylenumber}VAVAVAVAVAVA 12345}\par
Line 6: {\addff{oldstylenumber}VAVAVAVAVAVA 12345}\par
\stoptext

Line 4 and 6 should be significantly shorter too.
I tried the variable and the static versions.
In fontforge I can see a kerning of -80 between A and V.
My context is the newest lmtx.

Greetings Lutz
