Hello all,
The example below continues to work with MkIV, but now fails with the most recent (ConTeXt ver: 2021.10.24 21:45) LMTX:
\define\DraftOf {Draft of \date}
\setupinteraction [date={\DraftOf}]
\starttext
Fail with LMTX, works with MkIV.
\stoptext
If the answer is "don't do that" I can find another way to accomplish what this does -- not a big problem. But I do want to point out the difference in behavior.
