Incompatibility between the fall 2020 LaTeX release and the packages xwatermark and catoptions

Hi,

I just want to report that the aforementioned packages stopped working
after the fall 2020 LaTeX update (between September 29th and October
14th), because they change internal LaTeX macros.

https://github.com/latex3/latex2e/issues/411
but it is probably a "distribution" problem, in the sense that maybe
these package should be marked in some way (to report a warning or
something).

I want to take the opportunity to thank all for the good work on the
tex-live distribution. I use it a lot on a lot of linux distros and

I must also say that I was surprised to get a breaking change during an
in-release update :)

Compiling the MWE below gives error with texlive 2020 installed today,
but not with texlive 2020 installed around September 29th.

MWE:
\documentclass{article}
\usepackage{xwatermark}
\begin{document}
test
\end{document}

Thanks
Matteo Gamboz
