     Notes on tags used in MITgcmUV
     ==============================
 
+o move balancing of fluxes before the call of external_forcing_surf
+o seaice:
+  - correct units of turning angles (now they are really in degrees)
+  - move computation of GWATX/Y out of main routine into dynsolver
+  - initialize GWATX/Y in seaice_init
+o Apply mask on Fresh-Water flux (needed for SSH forcing).
+  update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual) 
+o seaice: add runtime flags for turning angles (default to zero)
+o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean 
+  and trend from exf forcing and ctrl control adjustments
+o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
+  (since checkpoint57x_post)
+o change the default rotation period to 86164.s = the Earth rotation
+o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
+  and based on a reference stratification. Tested within hs94.cs-32x32x5.
+o seaice advection: add code for choosing between the default (2nd order
+  central differences) and multiDim advection schemes provided by
+  pkg/generic_advdiff
 o seaice:
   - removed all references to SEAICE_GRID.h fields from 
     dynsolver, advect, diffus, lsr, without changing the results of lab_sea
     (cubed-sphere configuration will change a little)
   - grid computations in seaice_init are obsolete now.
   - cleaned up code a little so that is easier to read (hopefully).
-  - added new (better?) discretizations of advection and diffusion
-    (still commented out)
+  - added new (better?) discretizations of default advection and diffusion
+    (turn on with SEAICEuseFluxForm)
+  - replace 1 in 3d global fields by kSurface in growth.F
   
 checkpoint58a_post
+o seaice:
+  - bug fix in advect.F
 o shelfice: 
   - separate shelfice load anomaly from pload (breaks with time 
     dependent forcing), => introduce constant field shelficeLoadAnomaly.
