Dear list,
while doing some math typesetting, I have found the following features not working in LMTX:
1. Non-displaystyle operators are simply not shown (try \sum or \lim in text or scriptstyle). This works in MkIV (and iirc in LMTX versions from before november). 2. \underbrace{x}_{y} stopped working. It produces an underbrace but the subscript is not centered below the brace. It will show up as right subscript. This works in MkIV. 3. \startformulas does not allow numbering formulas because the number will run into the next column. I have posted this at
https://tex.stackexchange.com/questions/518262/context-number-formulas-side-... and Henri Menke tested that it broke in 2017. Aditya Mahajan mentioned that it is a bug.
For the upper two cases: Is anything wrong with my LMTX installation or did I miss some upgrade instructions for math in LMTX?
Many thanks for an answer.
Hi,
Regarding the first two issues your are reporting on, your file typesets correctly with my installation of LMTX (version 2019.12.04 21:35). I get the three different sizes of \sum as expected, and the underbrace has $n$ under the middle of the brace.
The third issue is present, as you are saying in your message. But I don't know what you are trying to achieve with two \startalign...\stopalign in the same formula.
Best regards: OK

fixed in next beta (relates to some new stuff in the engine related to some border case but often happening math spacing)
- \underbrace{x}_{y} stopped working. It produces an underbrace but the subscript is not centered below the brace. It will show up as right subscript. This works in MkIV.
idem

This one is for Aditya who knows more about these math alignments (needs) than I do.
Aditya: when we comment the \aligntab it's ok but i'm hesitant to do that patch ... so do you see bad consequences?

will be fixed
