     Notes on tags used in MITgcmUV
     ==============================
 
+o Added capability for latitudinal dependence of Bryan and Lewis, 1979
+  vertical diffusivity, similar to that in MOM4; vertical diffusivity is
+  specified using diffKrBL79* diffKrBLEQ* and KbryanLewisLatTransition
+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).

+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
+

 o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
   rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
