Hi all,
with
LuaTeX, Version beta-0.77.0-2013073017 (rev 4639)
and
ConTeXt ver: 2013.08.06 15:50 MKIV beta fmt: 2013.8.7 int: english/english
Context seems not to be able to typeset Labels anymore.
Yesterday, before an Update, all worked as expected.
Minimal not working example:
\starttext
\startMPpage
draw fullcircle scaled 5cm withcolor red;
label(textext("\CONTEXT"),origin);
\stopMPpage
\stoptext
