+\subsection{Improving the handling of \cs{label}, \cs{index}, and \cs{glossary}}
+
+In standard \LaTeX{}, the three commands \cs{label}, \cs{index}, and
+\cs{glossary} take exactly one mandatory argument, e.g.,
+\verb=\index{=\meta{entry}\verb=}=. In some extension packages, for
+example, in \pkg{index} or \pkg{cleveref}, they are augmented to
+accept an optional argument and in case of \cs{index} also a star
+form. These extensions conflict with \LaTeX's way of disabling the
+commands within the table of contents or within the running header,
+because there, they were redefined to expect just a mandatory argument
+and then do nothing. We have now changed that behavior so that the
+redefinitions in these places accept an extended syntax.
