+\subsection{Detect unicode engines when setting \cs{std at minus} and \cs{std at equal}}
+
+\pkg{amsmath} now detects the unicode engines and use their extended
+commands to define \cs{std at minus} and \cs{std at equal}. This avoids that package like
+\pkg{unicode-math} have to patch the code in the begin document hook to exchange the commands.
