+\subsection{Change behavior of tagging sockets with two arguments}
+
+When calling tagging sockets with two arguments using \cs{UseTaggingSocket}
+when tagging is suspended previous versions of \LaTeXe{} dropped both arguments.
+This behavior has been changed to drop the first argument and preserve the second
+one instead, thereby allowing tagging sockets to be used to wrap existing content
+which should still appear in a non-tagging context.
+
+Since no tagging sockets currently provided by \LaTeXe{} use two arguments
+we do not expect this change to affect any existing documents, but if a custom
+tagging socket has been defined outside of the kernel it might need to be adapted
+be compatible with the new behavior.
