+\subsection{Spacing commands moved from \pkg{amsmath} to the kernel}
+Originally \LaTeX{} only provided a small set of spacing commands
+for use in text and math, some of the commands like \cs{;} were
+only supported in math mode. \texttt{amsmath} normalized  and
+provided all of them in text and math. This code has now been
+moved to the kernel so that it is generally available.
