Not a bug, but new interface. You need: \definemathmatrix[matrix] [align={1:right,2:left,3:left}] It is also possible to say: align={all:middle}. Combination of the two don't seem to work. Aditya

Hi Hans and Aditya, Thanks for the clarification. Since for some documents I still use mkiv, I ended up using a definition which depends on whether one is using mkiv or lmtx, as in the example below. I wonder if there is a better solution. Best regards: Otared % begin bug-aligned-solved.tex \doifmode{mkiv}{\definemathmatrix[alignedcases] [align={right,left,left}, distance=3pt, left={\left\{}, right={\right.}, style=\displaystyle]} \doifmode{mkiv}{\definemathmatrix[matrix] [align={right,left,left}]} \doifmode{lmtx}{\definemathmatrix[alignedcases] [align={1:right,2:left,3:left}, distance=3pt, left={\left\{}, right={\right.}, style=\displaystyle]} \doifmode{lmtx}{\definemathmatrix[matrix] [align={1:right,2:left,3:left}]} \starttext \doifelsemode{lmtx}{We are using LMTX}{We are using mkiv} \placeformula[eq:1] \startformula \startalignedcases \NC \partial_{t} u \NC = \Delta u + \epsilon^{-2}f(u) \NC\qquad\text{in }\, \Omega\times (0,+\infty) \NR \NC {\partial\phi(u) \over \partial{\bi n}} \NC = 0 \NC\qquad\text{on }\, \partial \Omega\times (0,+\infty)\NR \NC u(x,0) \NC = u_{0}(x)\NC\qquad\text{in }\, \Omega.\NR \stopalignedcases \stopformula \startformula \startmatrix \NC ABC \NC ABC \NC ABC \NR \NC AAAAAA \NC AAAAAA \NC AAAAAA \NR \stopmatrix \stopformula % end bug-aligned-solved.tex

I confirm that this is a bug, which was not there in the version from mid Dec. Not a bug, but new interface. You need: \definemathmatrix[matrix] [align={1:right,2:left,3:left}] It is also possible to say: align={all:middle}. Combination of the two don't seem to work. basically we increment each element but a number sets the column so one can go to a specific column; empty (whatever non number will start again at zero)
