1. The bordermatrix code is part of the core and you can remove it from
cont-new.mkiv.
2. To use the \equalign command you have to enable the special meaning
of & in math mode with \setupmathematics[ampersand=normal].
3. User the new mathalignment environment as replacement for \equalign
which avoids special characters like &.

Dear list,
Some months ago, Hans wrote to this list (see below) a macro to do
matrix showing outside the brackets some informations (like we usually
do for Markov chains), but adapted some plain tex code, which worked
in MKII). I have used with success this code since then, but some
weeks ago, the behavior of Context had changed (probably something on
my part; I have updated the installation, but nothing changed).
The problem (I think) is linked to \unprotect \protect. When this code
is put before the \starttext to the the cont-new-mkiv, the border
matrix behave well, but a simple \eqalign like this:
\startformula
\eqalign{ & \lambda=5, \mu =5 \cr
& \mu=8 \cr }
\stopformula
do not works is I replace « \lambda » by « \lambda_2 » for example. I
have no idea what’s is going on. here is a minimal example where
Hans’s code is before the \starttext:
