     Notes on tags used in MITgcmUV
     ==============================
 
+o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
+     and update lab_sea output.txt file.
+
+checkpoint57y_post
+First step for a NLFS adjoint
+o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
+o new init. routines for calc_r_star, calc_surf_dr
+o still need to deal with ini_masks_etc
+o testreport seemed happy
+checkpoint57y_pre
+
+o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
+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,
