If you move floatrow earlier it works fine

\documentclass{article}
\usepackage{kpfonts}
\usepackage{floatrow}
\usepackage{booktabs}

\usepackage{siunitx}

\usepackage{pgfplots}

\begin{document}
Foo
\end{document}


essentially the difference is that siunitx no longer loads etex.sty as latex2015
uses extended registers automatically, however there can be
differences around the edges,
in particular you need to declare inserts before the classic registers
are allocated.
