     Notes on tags used in MITgcmUV
     ==============================
 
+o model/src/ini_curvilinear_grid.F: check in hack for SX8 compiler
+  to make sure that recip_dxV and recip_dyU are never zero, until we 
+  have a proper exchange for them. Most compilers do not seem
+  to mind divisions by zero in the overlaps, as long as the results are
+  not used anywhere, but sxf90 does. 
+o pkg/shelfice: fix bug with SHELFICEconserve flag, prepare for 
+  real fresh water flux (not yet)
+o pkg/mdsio & rw:
+ - add argument & option to S/R MDS_WRITEVEC_LOC (avoid Open/Close & write-meta)
+ - add simple interface S/R to MDS_WRITEVEC_LOC in pkg/rw: WRITE_GLVEC_RX.
+o pkg/flt:
+ - replace FLT_INIT by 3-steps standard initialization S/R: readparms,
+   init_fixed & ini_varia.
+ - clean-up & simplify linear interpolation S/R:
+   move flt_bilinear.F -> flt_interp_linear.F ; add arg. myThid.
+ - fix some indices (mainly vertical index) ; add IMPLICIT NONE.
+ - more efficient I/O, using new options of MDS_WRITEVEC_LOC S/R.
+ - add vert. coordinate & horiz. indices to output files.
+ - change vertical position in initial condition, from index to depth [m].
+ - store horizontal (decimal) indices i,j in common block (instead of coord. x,y)
+   (easier to get to a curvilinear grid) ; delX,delY no longer used.
+o pkg/ggl90: a few modifications:
+ - fix bottom boundary condition, and interpolation of KappaE
+   near top and bottom
+ - use same set of viscosity/diffusivity for TKE/momnetum/tracer 
+ - add smoothing option as in Blanke and Delecluse (1993) (--> ALLOW_GGL90_SMOOTH)
+ - add a few options for mixing-length upper limit (--> mxlMaxFlag)  
+o rename thetaMin,phiMin -> xgOrigin,ygOrigin
+  (maintain temporary backward compatibility, until next checkpoint)
+
+checkpoint61h
+o pkg/diagnostics with "periodic averaging diagnostics":
+  fix S/R DIAGNOSTICS_COUNT ; hack diagnostics_out.F to get NetCDF output. 
+o pkg/my82: add missing "_d 0" ; update output of exp. vermix.my82
+o pkg/obcs: fix loop ranges for balancing code
+o pkg/flt:
+ - improve criteria for finding which tile owns a float.
+ - fix FLT_EXCH for case without MPI ; apply cyclic BC + fix also the MPI case.
+o Add well-mixed CO2 box in aim_v23 (which includes changes in pkg
+  aim_compon_interf, ocn_compon_interf, gchem, and dic to get coupling
+  with ocean biogeo)
+o pkg/flt:
+ - do some cleaning and fix the restart ;
+ - add output.txt in flt_example/results to get this pkg tested.
+o genmake2: add an EXTENDED_SRC option and flag.
+   for now, cannot be turned on on command line (only through genmake_local)
+o pkg/mdsio: read/write vector:
+ - singleCpuIO: fix RL/RS in MDSWRITEVECTOR by calling new S/R MDS_BUFFERtoRL/RS
+ - singleCpuIO=F: fix arrType & filePrec & _BYTESWAPIO in both MDSREADVECTOR
+   & MDSWRITEVECTOR by calling new S/R MDS_RD/WR_VEC_RL/RS.
+ - affects gradient of test-exp "bottom_ctrl_5x5" (not due to _BYTESWAPIO)
+  (drop to 4 digits matching for grad). But this test does not look very
+  reliable (was already failling on eddy, fc5, at 6.digits). Update output.
+
+checkpoint61g
+o pkg/flt:
+  - move FLT_CPPOPTIONS.h to FLT_OPTIONS.h (standard name)
+   + make OPTIONS file more standard.
+  - rename S/R MDSREADVECTOR_FLT to FLT_MDSREADVECTOR (to mach src file name)
+  - fix _BYTESWAPIO CPP-Flag
+  - standard reading of file-parameter "data.flt"
+  - fix argument list of S/R FLT_RESTART
+  still need to fix _BYTESWAPIO in pkg/mdsio/mdsio_writevector.F
+o pkg/obcs: fix a CPP-flag, bug reported by Jeff Blundell
+o gather_2d.F/scatter_2d.F: suppress vectorisation on NEC SX in respond to
+  a still unfixed compiler/optimization bug
+
+checkpoint61f
+o pkg/seaice, LSR solver: fix bug in GLOBAL_MAX calls ; 
+  update results of global_ocean.cs32x15.icedyn test.
+o move getcon.F from model/src to pkg/fizhi.
+o pkg/exf: add parameter for extrapolation of temp up to the surface 
+   and option to prevent negative evap (in bulk_largeyeager04 only).
+o Prather Advection scheme: fix tracer conservation for divergent flow
+  (e.g., when using NonLin Free-Surface).
+o kpp: retire KPPmld diagnostics --> use MXLDEPTH instead
+o gmredi (Visbeck-variable-K):
+ - add more parameters to Visbeck-variable-K.
+ - use a 5 points average for dSigmaR in Visbeck-K calculation
+   (more "homogenous": same stencil and same weights as in dSigmaH)
+ - update output of ideal_2D_oce experiment.
 o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4 
   (#undef REAL4_IS_SLOW)
  - pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4 
@@ -16,6 +97,8 @@
    calling DIAGNOSTICS_FILL
  - model/inc/CPP_EEMACROS.h: make the _EXCH_*_RS macros expand into 
    real*4 (CALL EXCH_*_RS) versions.
+ - tested in 2 experiments: inverted_barometer & solid-body.cs-32x32x1
+   (generate new output).
