I update the TeX Live 2019 on my computer today. Then the behavior of \bfdefault
and \bfseries
changed, see the next MWE:
\documentclass{article}
\begin{document}
\bfdefault\\
{\fontseries{\bfdefault}\selectfont TEXT}\\
{\bfseries TEXT}
\end{document}
The result before updating:
The \bfdefault
was bx
and it changed to b
.
The \bfseries
is not equivalent to \fontseries{\bfdefault}\selectfont
after updating.
Is this a bug? Or something else?
