     Notes on tags used in MITgcmUV
     ==============================
 
+checkpoint44b_pre/_post
+o merge of relevant stuff from the ecco-branch:
+  - genmake: removed $S64 overwrite for case SunOS
+  - pkg/exf: update and corrections for field swapping and obcs
+  - pkg/ecco: parameter lists for the_model_main, the_main_loop
+              harmonized between ECCO and MITgcm
+  - pkg/autodiff: added flow directives for obcs, mdsio_gl_slice
+                  updated checkpointing_lev... lists for obcs
+  - model/src: minor changes in forward_step, plot_field
+               added directive for divided adjoint in the_main_loop
+  - pkg/mdsio: added mdsio_gl_slice
+
+next checkpoint:
+o check parameters & config (chkpt44a_pre,post)
+o OBC and NonLin_FrSurf.
+
+checkpoint44
+o fix bug in mom_vi_del2uv
+o select when filters are applied ; add options to zonal_filter (data.zonfilt)
+o gmredi: fix Pb in the adiabatic form ; add options (.e.g. Bolus advection)
+o update AIM experiments (NCEP input files)
+o improve and extend diagnostics (Monitor, TimeAve with NonLin-FrSurf)
+o added some stuff for AD
+
+checkpoint43
+o added two new advection tests
+o added global 4x4 degree ocean test
+o added test of H&S94 with free surface on cube
+o some final mods for gradient check, adjoint,...
+
+checkpoint42
+  Fixed AD-related problems:
+o Store directives up-to-date with re-arranged Adams-Bashforth
+  (mainly thermodynamics.F)
+o New store directives for multi-dim. advection schemes
+  * new CPP flag ALLOW_MULTI_DIM_ADVECTION
+  * new common block and key passkey
+  (mainly gad_advection.F)
+o Modified store directives for split of dynamics/thermodynamics
+  for the case ALLOW_KPP
+o Cleaned argument list for timestep_tracer.F
+
+checkpoint41
+o re-formatted/added comments in prologues of key subroutines
+  to work with protex
+
 checkpoint40
-o all changes of checkpoint40pre?
+o moved calc_gs, calc_gt and calc_tr1 back to model/src
+o added FLT (floats) package from Arne along with demo. experiment
+o re-arranged Adams-Bashforth scheme for tracers to allow easier
+  implementation of forward-in-time forcing terms
+o more mods for non-linear free-surface including new variable
+o modified multi-dim method to work on cube
+o bug fix in KPP (from DM)
+
+checkpoint40pre9
+o added DST advection schemes
+o fix MPI bug on SGI's
+o modifications for non-linear free-surface
+o fixed conditionals for fixed flow/passive tracer only mode
+o added tension/strain form of stress tensor
+o changes to commenting of arguments for TAF/TAMC
+o added/updated many matlab scripts
+o added multi-dimensional advection method for tracers
+  
+checkpoint40pre8
 o new package rw/
   Added method for dumping intermediate local arrays:
   mdsio_writetile - same as mdsio_writefield except works from inside
