kvoptions-patch breaks \usepackage[quiet]{fontenc}

[cjorssen]

With an up to date TeXLive 2020, the following does not compile nicely.

\documentclass{article}
\usepackage{kvoptions-patch}
\usepackage[quiet]{fontspec}
\begin{document}
Test
\end{document}

kvoptions-patch is no longer compatible with latex.

We will make it a no-op if the new latex is detected to avoid that it breaks packages like fontspec using \RequirePackageWithOptions .

Thanks for the commit and the explanation. I guess there will be similar issues with xkvltxp packge (xkeyval bundle).

A new version has been sent to ctan.
