This code now fails where before contextbeta had no problems:

tex error       > tex error on line 101 in file Info/waarneming.tex: ! Misplaced alignment tab character &

<recently read> &



l.101 H(I,J) &
             = H(I) + H(J|I)\qquad&\hbox{\ineq[eq:equivoc]}\cr

  99     \placeformula\startformula
100     \eqalignno{
101 >>  H(I,J) &= H(I) + H(J|I)\qquad&\hbox{\ineq[eq:equivoc]}\cr
102     W(I,J) &= H(J) - H(J|I)\qquad&\hbox{\ineq[eq:wedinfo]}\cr
103     }
104     \stopformula

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

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
