+\subsection{Support \eTeX\ length expressions in \texttt{picture} coordinates}
+
+Picture mode coordinates specified with \texttt{(\_,\_)} previously
+accepted multiples of \cs{unitlength}. They now accept \eTeX\ length
+expressions (as used by the \cs{glueexpr} primitive although all uses
+in \texttt{picture} mode are non stretchy).
+
+So valid uses include \verb|\put(2,2)| as previously,
+ but now also uses such as \verb|\put(\textwidth-5cm,0.4\texteight)|.
+
+Note that you can only use expressions with lengths, \verb|\put(1+2,0)| is not
+supported.
