-Note that color specification in font~definitions, such as
-\begin{lstlisting}
-\font\test=file:lmromandunh10-regular.otf:color=FF0000BB % \font primitive
-\addfontfeatures{Color=00FF00} % fontspec
-\end{lstlisting}
-are not compatible with \LuaTeX-ja in plain \LuaTeX\ and \LaTeX~2019-10-01~(or prior).
-So we recommend to use \LaTeX~2020-02-02.

-なお,フォント定義の際の色指定,例えば
-\begin{lstlisting}
-\font\test=file:lmromandunh10-regular.otf:color=FF0000BB % \font primitive
-\addfontfeatures{Color=00FF00} % fontspec
-\end{lstlisting}
-は,plain \LuaTeX や\LaTeX~2019-10-01以前において\LuaTeX-jaとは\emph{共存しない}.
-そのため,\LaTeX~2020-02-02以降を用いることを勧める.
