Package: texlive-math-extra Version: 2015.20160215-1 The following document demonstrates several problems introduced with texlive 2015.
\documentclass{minimal} \usepackage[bold-style=ISO]{unicode-math} \setmathfont{xits-math.otf} \renewcommand{\v}[1]{\ensuremath{\mathbf{#1}}} \begin{document} \noindent Is this $v{\nabla}$ a nabla?\\ Is this vector $\v{r}$ slanted?\\ Does this vector $\v{\hat n}$ carry a hat? \end{document} The problems, all in math mode: - Bold special symbols like \mathbf{\nabla} are not rendered at all. - Bold latin letters are not rendered slanted. - Within \mathbf{..}, carets, tildes &c are not rendered. Under texlive 2014, the rendering was correct.
