+\subsection{Main Updates in DRAGON}\label{sect:Updates}
+
+The frozen version (DRAGON Release 3.06) has seen a large number of changes since
+the first official release of the code (DRAGON\_960627).
+
+\vskip 0.15cm
+
+The following DRAGON package (DRAGON Version4) is an evolution of the frozen version,
+released as an attempt to introduce innovative capabilities:
+
+\begin{itemize}
+
+\item The self-shielding module \moc{USS:} allow increased accuracy and better representation
+of phenomena such as {\sl distributed self-shielding effects} and {\sl mutual self-shielding effects}.
+
+\item The new flux solution solver MCCG is an implementation of the long characteristics method proposed
+by Igor Suslov. This solver is initiated by the new tracking module \moc{MCCGT:}.
+
+\item The new flux solution module \moc{FLU:} is a complete rewrite of the outer iteration
+for the multigroup flux calculation that is now compatible with the method of characteristics and with
+any other approach requiring inner iterations. The \moc{MOCC:} module is no longer required.
+
+\item The burnup module \moc{EVO:} was extended to take into account energy produced by radioactive
+decay and by reactions other than fission.
+
+\item The new module \moc{COMPO:} is used to create and increment a multiparameter reactor database. The
+module The companion module \moc{NCR:} is used to interpolate an existing multiparameter reactor database.
+
+\item The flux solution solver SYBIL related to 2D assembly calculations was extended to allow
+sectorization of the cells.
+
+\item The method of discrete ordinates is implemented in tracking module \moc{SNT:}.
+
+\item The \moc{EXCELL:} module has been removed, but its capability is now implemented using the \moc{XCLL} keyword
+in \moc{EXCELT:}.
+
+\item The \moc{LIB:} module can access NDAS-formatted cross-section libraries.
+
+\end{itemize}
+

+
+The current DRAGON package (DRAGON Version5) is a rewrite of the code around the GANLIB5 kernel\cite{ganlib5}, intended to be 64-bit clean.
