To see a non contrived example where the change breaks existing
documents, take this example
(using a math expression from the breqn package documentation)
\documentclass[]{article}
\usepackage{breqn}
\begin{document}
aaaaaaaaaaaaaaaaaaa
\begin{dmath*}
g = 0 + 1 - 1
\end{dmath*}
aaaaaaaaaaaaaaa
\begin{dmath*}
T(n) \hiderel{\leq} T(2^{\lceil\lg n\rceil})
\leq c(3^{\lceil\lg n\rceil}
-2^{\lceil\lg n\rceil})
<3c\cdot3^{\lg n}
=3c\,n^{\lg3}
\end{dmath*}.
\end{document}
I attach the output from xelatex 2014 and 2015,
basically breqn doesn't work with xelatex 2015.
I haven't fully traced it but I suspect (since math lists are opaque now)
that this is not fixable by changing macro code.
