Hi Have updated my standalone installation from one of the 2020 releases to the latest one running

./first-setup.sh --context=latest --modules=all

Hi Christoph,

sorry for the obvious suggestion «post facto»: never update ConTeXt without a backup first.

...

[...] Therefore i have the following questions - would it help to sacrifice the updated standalone installation and do a fresh install

I don’t think it would work, since it only works with LuaMetaTeX.

I got the same results (in Windows [because I cannot make it work in Linux]) with LuaTeX 1.15 (the one that comes with ConTeXt LMTX).

My suggestion would be a fresh install (in a different directory, no need to remove anything) of ConTeXt LMTX.

...

- What else i would have to check and probably fix to make the math working as expected

Math is being improved in ConTeXt these days. It might be a bug.

I wonder whether Mikael or Hans could review your issue.

Just in case it might help,

The strange thing with fractions seems to be due to the parameter FractionNumeratorDisplayStyleShiftUp in lm.lfg. If you always set it to 600, it seems to work also for luatex. (This will be fixed.) Another thing: Instead of using \over, I suggest that you use \frac (less surprises). Something like: \starttext \startformula a=b + 1 \stopformula \startformula a = \frac{ b + \mu }{ c } \stopformula \startformula a = \frac{\frac{ b + \mu }{ c } + e}{ d + i } \stopformula \stoptext /Mikael

Thank you very much for the hints. \frac didn't help either even after moving broken installation aside and doing a fresh install with

sh ./first-setup.sh --modules=all --context=latest

Results still similar see attached. We had to adapt the lfg file for lm (other fonts are ok) so i'll make an update.

If you're in a hurry, in lm.lfg: parameters = { FractionNumeratorDisplayStyleShiftUp = 600, -- used to be a function NoLimitSupFactor = 0, NoLimitSubFactor = 900, -- AccentBaseHeight = 0, AccentBaseDepth = 50, }, can be adapted.

That's fine. As soon as post that update is ready for pulling I will pull. Till then i can wait.

Hi Christoph, to check when there is a new release I use: curl -I https://lmtx.pragma-ade.com/install-lmtx/texmf-context.zip 2>&1 | grep -i Last-Modified Just in case it might help you, Pablo
