Hi Hans, Since a few weeks (or months?…) ago the use of \eqno and \eqalignno has been changed in mkiv. It is better to use the construction such as: \placeformula \startformula \startalign \NC H(I,J) \NC = H(I) + H(J|I) \NR[eq:equivoc] \NC W(I,J) \NC = H(J) - H(J|I) \NR[eq:wedinfo] \stopalign \stopformula Best regards: OK

This code now fails where before contextbeta had no problems:

This happens in ConTeXt ver: 2017.04.16 12:32 MKIV beta fmt: 2017.4.16 int: english/english I am not sure when this started to happen, but for sure after 2016-02-12.

Here is a minimal example to run:

\starttext \placeformula\startformula \eqalignno{ 3x - 4y &= 5 \cr x + 7 &= -2y \cr z &= 2 } \stopformula \stoptext
