+\subsection{Add \pkg{ltcmd} support for \cs{NewCommandCopy} and \cs{ShowCommand}}
+
+Since the 2020-10-01 release (see~\cite{34:ltnews32}), \LaTeX{} provides
+\cs{NewCommandCopy} to copy robust commands, and \cs{ShowCommand} to
+show their definition in the terminal.  In the same release, the
+\pkg{xparse} package was integrated in the kernel (now called
+\pkg{ltcmd}).  But since then, the support for \cs{NewCommandCopy} and
+\cs{ShowCommand} was not implemented in \pkg{ltcmd}.  The present
+\LaTeX{} release ships with that support implemented, so now commands
+defined with \pkg{xparse}/\pkg{ltcmd} can be copied and their definition
+can be easily shown in the terminal without \cs{csname} gymnastics.
