 \section{Code improvements}
 
+\subsection{Tab character as a special}
+
+In \LaTeX{} News~38, we described the extension of \cs{verb}, etc., to cover
+the tab character as equivalent to a space. We have now added tabs to the
+standard list of characters covered by \cs{dospecials}. This allows them to
+used in for example a \texttt{v}~specification document command without
+additional steps.
