Several math features broke for me in new Debian version
Dear Friends,
I am a regular user of ConTeXt. A recent upgrade of ConTeXt in Debian
broke things for me. The bug report is here:
https://bugs.debian.org/1055233
but I have reproduced the gist here:
Upon upgrading to ConTeXt 2023.05.05.20230730+dfsg-2, several math
features seem to break for me. Here is an example:
\starttext
Hello world!
\startformula
X(f) = \startcases[align={right,left},distance=3pt]
\NC T, \NC{} $|f| < \frac{1}{2T}$ \NR
\NC 0, \NC{} $|f| \geq \frac{1}{2T}$ \NR
\stopcases
\stopformula
\stoptext
The above works very well in 2021.03.05.20230120+dfsg-1+deb12u1 but
gives me this error in 2023.05.05.20230730+dfsg-2:

There has been changes in the math alignment mechanism a while ago and the cases environment use math mode for a column entry when you use the \NC tag at the begin of a cell, to make your example working again remove the $ in the column. \starttext \startformula X(f) = \startcases \NC T, \NC |f| < \frac{1}{2T} \NR \NC 0, \NC |f| \geq \frac{1}{2T} \NR \stopcases \stopformula \stoptext To typeset the content of a column as text replace \NC with \TC at the begin of the cell.

Thank you for pointing this out. For now, I shall refrain from upgrading, since this is a backwards incompatible change that affects many files. Eventually, I'll make the required changes. Kumar -- Kumar Appaiah
