Yes, something has changed internally. Earlier, if you used:
\startalign[align={right,left}, n=4]
...
\stopalign
then the alignment was right left right left, i.e., the alignment cycled. Now,
the alignment is right left left left, i.e., unspecified alignments default to
left. So, in your example, each column in the second "block" is left aligned.
To change that, you can use:
\starttext
\startformula \startalign[m=2,distance=8em,n=5,
align={right,middle,middle,middle,left, right,middle,middle,middle,left}]
\NC 0 \NC < \NC 2x + 5y \NC < \NC 10
\NC 4 \NC < \NC 3x + y \NC < \NC 9 \NR
\NC 3 \NC < \NC 2y + 3z \NC < \NC 15
\NC 10\NC < \NC 8y + 5z \NC < \NC 20 \NR
\stopalign \stopformula
\stoptext
But this is ugly.
I haven't looked at the math alignment code in a while, but I'll check with
Hans if the old behavior can be reintroduced.
