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-by-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)

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?
\def\math_alignment_NR_indeed[#1][#2]%
{%\aligntab % HERE
\dostoptagged % finish cell
\strc_formulas_place_number_nested{#1}{#2}%
\math_number_right_of_eqalign
\global\settrue\c_math_eqalign_first
\crcr
\dostoptagged} % finish row

will be fixed
