 This manual is organised in as follows. Chapter~\ref{PE} presents the model basics, 
 $i.e.$ the equations and their assumptions, the vertical coordinates used, and the 
 subgrid scale physics. This part deals with the continuous equations of the model 
-(primitive equations, with potential temperature, salinity and an equation of state).

+$\bullet$ The main modifications from NEMO/OPA v3.4 and  v3.6 are :\\
+\begin{enumerate}
+\item I/O management: NEMO in now interfaced with XIOS, a Input/Output server having a versatile xml user interface, and 
+allowing I/O to be performed on dedicated processors thus improving scalability and performance on massively parallel platforms. 
+\item ICB module \citep{Marsh_GMD2015}: icebergs as lagrangian floats ; 
+\item SAS: Stand Alone Surface module allowing testing of forcing set with bulk formulae, to run sea-ice models without ocean, to run ICB icebergs module alone, and to test AGRIF with sea-ice
+\item ISF : Under ice-selves cavities (parametrisation and/or explicit representation)
+\item Coupled interface for next IPCC requirements (multi category sea-ice, calving and iceberg module)
+\item Ocean and ice allowed to be explicitly coupled through OASIS, using StandAlone Surface module)
+\item On line coarsening of ocean I/O
+\item Major evolution of LIM3 sea-ice model \citep{Rousset_GMD2015}
+\item Open boundaries: completion of BDY/OBC merge : BDY is now the only Open boundary module available
+\item re-visit of the specification of heat/salt(tracers)/mass fluxes ;
+\item levitating or fully embedded sea-ice (for LIM and CICE) ;
+\item a new parameterization of mixing induced by breaking internal waves (de Lavergne et al. in prep.)
+And also:
+\item update of AGRIF package and AGRIF compatibility with LIM2 sea-ice model ;
+\item A new vertical sigma coordinate stretching function \citep{Siddorn_Furner_OM12} ;
+\item Smagorinsky eddy coefficients: the \cite{Griffies_Hallberg_MWR00} Smagorinsky type diffusivity/viscosity for lateral mixing has been introduced ;
+\item Standard Fox Kemper parametrisation
+\item Analytical tropical cyclones taken in account using track and magnitude observations (Vincent et al. JGR 2012a,b) ;
+\item OBS: observation operators improved and now available in Standalone mode ;
+\item Log layer option for bottom friction
+\item Faster split-explicit time stepping ; 
+\item Z-tilde ALE coordinates \citep{Leclair_Madec_OM11} ; 
+\item implicit bottom friction ;
+\item Runoff improved and SBC with BGC
+\item MPP assessment and optimisation
+\item First steps of wave coupling

+Features becoming obsolete: LIM2 (replaced by LIM3 monocategory) ; IOIPSL (replaced by XIOS) ; 
+
+Features that has been removed : LOBSTER (now included in PISCES) ; OBC, replaced by BDY ;
