\subsection{Supporting the \texttt{ssc} and \texttt{sw} shapes}
274+
275+
The \texttt{ssc} shape (spaced small capitals) is supported in
276+
\LaTeX{} through the commands \cs{sscshape} and \cs{textssc}. However,
277+
until this release there where no font shape change rules defined for
278+
this admittely seldom available shape, so that
279+
\begin{verbatim}
280+
\sscshape\itshape
281+
\end{verbatim}
282+
changed unconditionally to \texttt{it} (italics) rather than to
283+
\texttt{sscit} (spaced small italic capitals). Thanks to Michael
284+
Ummels, the missing declarations have now been added so that shape
285+
changes in font families that support spaced small capitals work
286+
properly.
287+
288+
At the same time we took the opportunity to improve the fallbacks for
289+
the \texttt{sw} (swash) shapes, which are accessible through the
290+
commands \cs{swshape} or \cs{textsw}. If an \texttt{sw} combination is
291+
not available, the rules now try to replace \texttt{sw} with
292+
\texttt{it} rather than falling back to \texttt{n}.
