     Notes on tags used in MITgcmUV
     ==============================
 
+o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
+o add new offset feature to offline pkg (plus minor cleanup)
+o cfc fixes for final year of integration
+o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
+  be in GCHEM_OPTIONS).
+
+checkpoint57x_post
+o fix testreport Pb in multiple test experiment.
+o cleanup our namelist syntax in verification:
+  - make it more F95 standards compliant (some work still needed)
+  - allows the vast majority of our tests to work with gfortran
+o Non-Hydrostatic:
+ - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
+ - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
+o Allow to apply AB on T,S rather than on AB(gT,gS):
+ - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
+ - use the same arrays (gtNm,gsNm) to hold tracer field at previous
+   time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
+ - need a "clever" read_pickup to restart from the other AB formulation
+o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h 
+o remove some unused variables (reduces number of compiler warnings)
+o adjoint
+  * Disable useVariableViscosity for adjoint for time being
+    (there are a number of extensive recomputations)
+  * Initialize certain variables needed for adjoint
+
+checkpoint57w_post
+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.
+
+checkpoint57v_post
+o change dome exp. to use variable viscosity in side-drag terms.
+o remove all the files from the cfc_offline test since they are now
+  incorporated into tutorial_cfc_offline which has been producing
+  identical results for a few days of testing
+o add new parameter: sideDragFactor to enable half-slip-side BC
+  and change side-drag S/R to use viscosity from mom_calc_visc
+  (can switch back by setting sideDragFactor=0.); affects results at 
+  truncation level; regenerate output for exp.: global_ocean.cs32x10(x3), 
+   global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
+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.
+o modify exp4 to test new obcs support for reading from external files
+  and for passive tracers
+o fix behavior of ptracers_monitor when monitor output is written to a 
+  netcdf-file; still not independent of monitor.F (writes in the same
+  file).
+o change default value of tRef (put a uniform, meaningful value for ocean 
+  & atmos) and initialize sRef (was missing, as Martin mentioned).
+o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity 
+  to be proportional to enstrophy dissipation length.  Thus,
+   viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
+  This is now consistent with Smagorinsky and with the manual.
+
 checkpoint57u_post
 o OBCS and PTRACERS: add open boundary support for passive tracers
   - either use homogenous (pseudo) v.Neumann conditions or prescribe
