It seems that with the latest beta there is a bug in the way how the command \text is handled in step charts (plesae see the attached PDF). This bug is absent from mkii, and absent from previous versions of mkiv (up to a weak ago, I believe).
This is a minimal example which shows that the font used in each cell of \text changes randomly (there are four instances of \text, and each time a different font is used…):
%%%% begin random-text-size.tex \usemodule[steps]
\starttext \input knuth.tex
\placefigure[none][-]{}{ \startSTEPtable \cell {$(f\circ u)(x_{*} + o(1)) = $} \text{definition of $f\circ u$} \cell {$f\left(u\left(x_{*} + o(1)\right)\right) = $} \text {$u$ is continuous} \cell {$f\left(u(x_{*}) + o(1)\right) = $} \text {$f$ is continuous} \cell {$f\left(u(x_{*})\right) + o(1) =$} \text {definition of $f\circ u$} \cell {$(f\circ u)(x_{*}) + o(1)$.} \stopSTEPtable}
\stoptext %%%% begin random-text-size.tex
This bug arises from low-level changes in the handling text from MetaPost. I have reported this to Hans (in the context of graphs), although I have not understood how to fix it. The result is kind of fun: like something that many people produced at the time of the introduction of the Apple MacIntosh! Alan
