     Notes on tags used in MITgcmUV
     ==============================
 
+o pkg/seaice: fix bug in evp solver, while doing that
+  - change (improve?) discretization of stress computations for both
+    cgrid-lsr and evp solver
+  - add a new routine to compute strain rates
+  - the above changes lab_sea results
+  - add no slip conditions for evp solver (off by default), lsr-version
+    may follow
+  - fix exchange for shear at Z-points (does not change lab_sea)
+  - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
+    (to force the user to pick a time step since there is not "safe" way
+    of choosing it)
+o pkg/kpp: add code to have mixing in shelf ice caverns
+
+checkpoint59
+o pkg/exf: 
+  - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
+    ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
+  - move exf header files from lower_case.h to UPPER_CASE.h ; 
+    add missing cvs Header & Name
+  - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
+  - add namelist param. selectStressGridPosition, exf_monFreq
+  - retire many _CLIM routines, and remove data.exf_clim 
+    + params moved to data.exf
+    + climsst, climsss now handled by exf_set_gen, i.e.
+      climss?period=0 refers to constant field,
+      climss?period=-12 to monthly forcing
+  - split up namelists in data.exf
+o pkg/seaice:
+  - remove seaice_exch and seaice_exch_uv
+  - remove superfluous exchange of theta
+  - add myThid to seaice_budget_ocean/ice
+  - add new interface for atmospheric wind forcing (C-grid only)
+    + new routine
+    + two new field (taux, tauy for stress over ice)
+    + removed one global field (DAIRN) for C-grid case only
+o pkg/thsise
+  - 2nd set of modifs for thsice adjoint in conjunction with exf
+o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
+
+checkpoint58y_post
+o Added capability for latitudinal dependence of Bryan and Lewis, 1979
+  vertical diffusivity, similar to that in MOM4; turned on using
+  #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
+  diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
+o Added capability for 3D specification of background vertical diffusion
+  coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
+  in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
+  "data" file that contains the 3D vertical diffusivity coefficients.
+o ice dynamics (pkg/seaice) with thsice thermodynamics:
+  - add code within pkg thsice to advect & diffuse sea-ice fields
+  similar to (and will replace) what has been added in  seaice_advdiff.F,
+  but: - conserving Mass, Heat & Salt.
+       - better when using non-linear advection scheme (not yet fully tested)
+       - can also be used in atmospheric set-up (for now, only the diffusion).
+
+checkpoint58x_post
+o IO option for global-file compact format:
+  - add options when generating topology (utils/exch2/matlab-topology-generator)
+  - add I/O capability (pkg/mdsio).
+  - adapt utils/matlab/rdmds.m to read this format.
+  for now long-line format not yet supported by pkg/mdsio (& exch2).
+o shelfice: add a few diagnostics
+
+checkpoint58w_post
+o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
+  rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
+  (and replace horiVertRatio in NH code).
+  Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !) 
+                     and tutorial_plume_on_slope (sensitive to truncation)
+o seaice: if ALLOW_ATM_WIND is undefined use wind stress
+  directly to drive seaice model (C-grid only)
+o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
+ - reintroduce computation of wind from stress, 
+ - compute tau (in exf_bulkformulae.F) from windstress averaged to 
+   mass points to avoid tau = 0
+ - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
+o rdmnc.m: make it work with "global" files created with gluemnc
+o rdmnc.m : some improvements in dealing with singleton dimension
+  (tested on all testreport mnc output files).
+o genmake2: disable pkg/profiles if netcdf test fails.
+o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
+o move call to cal_readparms up to make calendar parameters/variable available
+  to all packages
+
+checkpoint58v_post
+o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
+  useDynP_inEos_Zc tested.
+o pkg/exf: changes to properly interpolate/mask/scale initial fields
 o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
   and portions thereof.  See read_cs.txt for description and examples.
 o utils/matlab/cs_grid/bk_line: to compute transport through passages,
