     ==============================

+o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
+             fix the singleCpuIO RS version of MDSWRITEFIELD
+   and add a WARNING if using globalFiles=T with multi-processors.
+o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
+  using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
+o tracer advection scheme:
+  add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get 
+   those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile, 
+   was not very convenient).
+  add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
+   (further tests needed for the implicit DST & Flux-Limiter schemes).
+o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
+  and sRef for convenience, handy, when you want to initialize
+  ptracers in a large domain with a constant non-zero value. Also,
+  untangle ptracers_init.F a little.

 o vorticity & strain are now computed without masking, to account for 
   no-slip-side BC in variable viscosity calculation ; mask is applied
   anyway later on, before computing advection/coriolis terms.
