     Notes on tags used in MITgcmUV
     ==============================
 
+o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
+  - change discretisation of evp-solver in order to avoid another exchange
+    (changes lab_sea) and clean up a little
+  - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS) 
+    help the adjoint (this also changes the results slightly)
+  - add a few "_d 0" where they had been missing in seaice_evp.F
+  - cleaning up: remove unused seaice_calc_rhs.F
+o pkg/exf: some cleaning-up:
+  - change various "constants" into runtime parameters
+  - cleaned-up Large&Yeager04 routine which should eventually
+    replace exf_bulkformulae.F (changed names of S/R and CPP)
+    and merged various ALLOW_ATM_WIND options
+ only used with thsice pkg (in thsice_get_exf.F):
+  - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
+    which are used when useStabilityFct_overIce=TRUE (= the default)
+  - change default values of ice & snow emissivity and scale downward LW
+    by ice & snow emissivity.
+o pkg/thsice:
+ fix few little problems, in thsice_calc_thickn.F:
+  - growth vertically (and not laterally) if iceFrac == iceMaskMax
+  - melt laterally only if hIce < hThinIce (as the comments say)
+  and in thsice_extend.F:
+  - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
+  - start to form ice as soon as the minimum ice-volume is reachable.
+ update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice), 
+  and cpl_aim+ocn
+o pkg/kpp
+ - move computation of surface related input fields to KPP into a new
+   subroutine kpp_forcing_surf.F
+ - remove wrong (within bi,bj loops) EXCH calls.
+ - little cleaning (add argument myThid in last position, cvs header ...)
+ - for now, fix conservation problem by exchanging KPPviscAz (may not 
+   be the best fix)
+o pkg/seaice
+ - check for inconsistent evp parameter/cpp-flag combination
+ - remove leftover errIO flat for obsolete name list error handling
+o OpenAD
+ - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
+
+checkpoint59a
+o pkg/seaice: some parameter clarifications and a little bit of clean up
+o pkg/thsice: rename run-time parameters:
+   himin       -> hIceMin
+   himin0      -> hThinIce
+   hihig       -> hThickIce
+   i0          -> i0swFrac
+   transCoef   -> bMeltCoef
+   frac_energy -> fracMelting
+  add new parameters: hNewIceMax, fracFreezing, dhSnowLin
+   with default values (for now) that do not change the results.
+  remove old version of thsice vars advection in pkg/seaice.
+o in FFIELDS.h: 
+  - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
+  - make pLoad & sIceLoad always available (but still only used if
+     ATMOSPHERIC_LOADING is #define).
+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
+  - add myThid to all kpp routines (long overdue)
 
 checkpoint59
 o pkg/exf:
