     Notes on tags used in MITgcmUV
     ==============================
 
+o pkg/kpp: replaced _KPP_RL with _RL
+o bug fixes for vertical diffusivity computations when both KPP and
+    3D diffusivity arrays are used.
+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)
+  - add principal stress diagnostics
+  - rearrange fields for evp a little to avoid having to call a: too many 
+    exchanges and b: exchanges for stress trensor components which we do 
+    not have.
+  - modify Hibler+Bryan (1987) stress coupling so that it reuses information
+    of evp, complete rewrite for lsr case (latter is does not yet work
+    in all cases)
+o pkg/kpp: add code to have mixing in shelf ice caverns
+

 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
@@ -20,6 +51,7 @@
     + 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.)
