Hi Hans,
I have two issues with variable fonts (using current latest from yesterday):
1. Using the following sample:
\usemodule[fonts-variable]
  \starttext
   \showfontvariations[font=file:grenze.ttf]
  \stoptext
With the fonts from
https://github.com/Omnibus-Type/Grenze/tree/master/fonts-/gx, I get the
following error message:
lua error:
   run callback [6]:
...ext/tex/texmf-context/tex/context/base/mkxl/lpdf-emb.lmt:84: number
(local 'n') has no integer representation
stack traceback:
    ...base/mkxl/lpdf-emb.lmt:84: in upvalue 'tocardinal2'
    ...base/mkxl/lpdf-emb.lmt:771: in local 'writer'
    ...base/mkxl/lpdf-emb.lmt:2358: in field 'integer index'
    ...base/mkxl/lpdf-ini.lmt:828: in upvalue 'run'
    ...base/mkxl/lpdf-ini.lmt:859: in field 'finalizedocument'
    ...base/mkxl/lpdf-lmt.lmt:3413: in field '?'
    ...base/mkxl/luat-run.lmt:58: in function
      <...ext/tex/texmf-context/tex/context/base/mkxl/luat-run.lmt:56>
<empty file>
mtx-context     | fatal error: return code: 1
This crashes LuaMetaTeX but not LuaTeX.
i'll catch it
...
2. The other font is Recursive
(https://github.com/arrowtype/recursive/tree/main/fonts/recursive_for_googlef...).
\usemodule[fonts-variable]
  \starttext
   \showfontvariations[font=file:recursive.ttf]
  \stoptext
There are some some instances (in pages 4 to 14) that don’t have the
font (only Latin Modern Roman).
i'll catch it
...
Also in the last instances (at least, pages 19 to 25), kerning or
interletter spacing clearly needs to be improved.
no clue (ok, a little)
Hans
