     Notes on tags used in MITgcmUV
     ==============================
 
+o argument futureIter of S/R obcs_calc missing in exp4 & internal_wave /code
+o solve_for_pressure : set cg2d_x to zero where OBCS are applied
+
+checkpoint44h_post = checkpoint45
+o Fix to restore differentiability:
+  place at which packages_init_variables is called in
+  initialise_varia is crucial for reverse control flow.
+o modifications in GMRedi to enable stable adjoint
+  (corresponding modif's in thermodynamics, dynamics)
+o added missing hook for sponge layer code in external_forcing
+o modified test cost functions
+o storing in gad_advection (plus removal of write(0,*)!
+o missing headers TR1.h added in convective_adjustment routines
+o errorMessageUnit set non-equal zero in eeboot
+  (conflict on some platforms, e.g. IBM SP3)
+o modified carbon verif.
+
+checkpoint44h_pre
+o vertical grid option: allow to put the Interface at the middle between
+  2 cell-centers ; replace delZ in pkg/kpp by drF.
+o GM Advective form: Tracers are advected using the residual transport (=
+  Euler+GM-bolus); set param GM_AdvSeparate=T to return to previous form.
+
+checkpoint44g_post
+o fix surface correction term in multiDimAdvection (affects plume_on_slope 
+  results) ; ifdef missing in thermodynamics.F
+
+checkpoint44f_pre,checkpoint44f_post
+o added PTRACERS package
+  This allows an arbitrary number of passive tracers to be integrated
+  forward simultaneously with the dynamicaly model.
+  + Implemented so far:
+    - basic forward algorithm (time-stepping, advection, diffusion, convection)
+    - I/O and checkpointing
+    - GM/Redi  *but*  using the GM/Redi coefficient of Salt
+  + Not implemented so far:
+    - KPP
+    - OBCS
+  + No specific example supplied (yet) but global_ocean.90x40x15 has the
+    necessary data.ptracer file. Simply use -enable=ptracers and uncomment
+    line in data.pkg.
+  + This package is disabled by default since it increases storage.
+
+
+o testscript: added -cleanup option
+o Shap_filt: a) new shap_filt S/R to use no-slip BC with S2 filter
+             b) enable to filter 2D fields.
+
+checkpoint44e_pre,post
+o re-wrote convective adjustment to use pre-calculated weights
+  Affects: model/src/convective_adjustment.F, convective_adjustment_ini.F
+  Adds:    model/src/convective_weights.F, convectively_mixtracer.F
+  Original calls to convect() still in place.
+
+chkpt44d_pre,post
+o added missing EXCLUDE_MONITOR flags
+o changed "e" to "_d" in gmredi_slope_limit, gmredi_slope_psi
+  (incompatible typ in MIN/MAX expressions caused problems
+  on IBM SP3)
+o in genmake added variable MAKEDEPEND
+  plus resetting for case SunOS
+o added timer_stats.c routine for IBM SP3
+o removed variables in dynamics
+!!! I forgot to create tag chkpt44d_pre !!!
+!!! But chkpt44d_pre = chkpt44c_post    !!!
+
+o real fresh water flux implemented with non-linear free-surface.
+
+chkpt44c_pre,post
+o few fix (mask in shap_s2, EmPmR in external_field_load, 
+  USE_NATURAL_BCS in solve_for_P); 
+o add arguments myIter & myTime to S/R obcs_calc & solve_for_P
+
+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
+
+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
