Hans,

Let me rephrase the question.

With the following example:

\starttext

\contextkind

\stoptext

The standalone installation returns a document containing "beta" and context --luatex with the LMTX installation complains of an undefined control sequence.

The file context.mkiv differs between the two installations.

If the two are expected to differ, I am asking which is the reliable version.

You had stated in an earlier email that the --luatex option provided to an LMTX installation will produce an MkIV result, but that does not seem to still be the case.

My apologies to Hans and the list. My MkIV installation reverted to the 2020-01-30 release at some point in late September or early October. I have corrected that and now see no differences other than version strings in the source directory.
