Compatibility with amsmath is broken

[tweh]

Due to some changes in the implementation of \genfrac in amsmath the compatibility is broken and in (de)nominators \mathstyle doesn’t give the right/expected result. Please see Value of LuaTeX’s \mathstyle in \frac (de)nominator on TeX.SX for further details.

% !TeX program = lualatex
\documentclass{article}

\usepackage{amsmath}
\usepackage{lualatex-math}

\begin{document}
   $\dfrac{\mathstyle}{\mathstyle} \neq \dfrac{4}{5}$
\end{document}

Pleas note that \frac still works, as it is not defined using \genfrac.

Thanks for the report, and sorry for the slow response. I've adapted the patch; could you maybe check whether it works now for your use case?

sorry about that I should have checked and flagged that with you at the time:-)

Hi, seems to work now in the version I downloaded from the current master branch (\filelist → 2017/06/15 v1.7). For sake of completeness the CTAN version (\filelist → 2016/04/16 v1.6) does not work.

Thanks, I've uploaded the new version to CTAN.
