\part{Introduction}
\section{New in v1.5}
+\subsection{The primitive \texttt{\protect\textbackslash expanded}}
+As of version 1.54, \CF requires a \TeX{} engine that provides the \verb|\expanded| primitive. If this is not available, \CF will not be loaded. It is strongly recommended that you update your \LaTeX{} distribution in order to take advantage of the newer engine that provide for the use of this new primitive.

\subsection{The macro \texttt{\protect\textbackslash charge}}
Version 1.5 implements the macros \verb|\charge| and \verb|\Charge| (see page~\pageref{charge}) whose purpose is to place arbitrary elements around an atom that can be placed with great precision. These macros will replace the \verb|\lewis| and \verb|\Lewis| macros because they are much more powerful and configurable, even if more verbose. It is therefore important to note that the macros \verb|\lewis| and \verb|\Lewis| \textcolor{red}{\bfseries are no longer documented and will be removed from the \CF package}.
