+\subsection{Support fragile commands in \texttt{array} or \texttt{tabular} column templates}
+
+The preamble specifiers \texttt{p}, \texttt{m} and \texttt{b} receives
+a user supplied argument: the width of the paragraph column. Normally
+that is something harmless, like a length or a simple length
+expression. But in more complicated settings involving the \pkg{calc}
+package it could break with a low-level error message.  This has now
+been corrected.
