Break. texfig now must manually assigns LaTeX header part [texfig-0000]

Form @texfig{...} at before implicitly do

\usepackage{quiver}
\usepackage{tikz}
\usetikzlibrary{spath3, intersections, backgrounds}

for users, now they are removed. Hence you must write it out explicit

@texfig[#:header @"
\\usepackage{tikz}
\\usetikzlibrary{spath3, intersections, backgrounds}
"]{
...
}

The output Tex file you will get is

\documentclass[crop,dvisvgm]{standalone}
\usepackage{tikz}
\usetikzlibrary{spath3, intersections, backgrounds}
\begin{document}
...
\end{document}
