     Notes on tags used in MITgcmUV
     ==============================
 
+checkpoint50b_post
+o store u*,v* in gU,V instead of in guNm1,gvNm1
+o in order to put the momForcing out of the Adams-Bashforth:
+  move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
+  to timestep.F
+o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
+o re-generate output for highly sensitive test-exp:
+   global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
+
+checkpoint50b_pre
+o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
+o corrected CPP option mismatch in exf_Bulk... functions for case 
+  #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
+
+checkpoint50a_post
+o Bug fix for merging between c50 and KPP.
+  ikey was passed from thermodynamics to kpp_calc via
+  common block rather than being recomputed in kpp_calc,
+  in contradiction with new key itdkey.
+  New key ikppkey created, and tamc.h headers updated.
+
+checkpoint50
+- 2nd step of merge with ecco-branch:
+  merge changes in ecco-branch back into main trunk
+- bug fix in find_alpha
+- more storing in gmredi_calc_tensor.F, kpp_routines.F
+- avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
+- merged some sliced AD support routines
+
+checkpoint49
+merged from ecco-branch:
+o exf:
+  - Enable initialisation of forcing fields to constant 
+    (runtime) values.
+  - in exf_getffields.F
+    Reduce i-/j-loop to interior domain, discarding overlaps.
+    That also fixes wrong TAF-key computations for key_1, key_2
+    with bulf formulae.
+  - exf_init.F modify #ifdef for exf_init_evap
+  - exf_getffieldrec.F, ctrl_getrec.F
+    The following INT-usages are not safe:
+      fldsecs  = int(fldsecs/fldperiod)*fldperiod
+      fldcount = int(fldsecs/fldperiod) + 1
+    and were modified.
+o autodiff: checkpoint_lev...
+  - updated storing for bulk formulae (some arrays were missing)
+  - added state for seaice package
+  - synchronized with main branch
+o DIVA:
+  Modif.s in
+  - the_main_loop.F
+  - the_model_main.F
+  and added cost_final_restore.F cost_final_store.F
+  o With these changes, it is possible to fully separate
+    the first forward run to compute the cost function (mdthe_main_loop)
+    and adjoint runs over individual DIVA intervals (adthe_main_loop)
+    into separate model executions.
+    This enables better tuning of DIVA to given queue sizes.
+  o Loss of cost function value in consecutive DIVA runs is
+    fixed by storing to 'costfinal' file.
+  o Appropriate call of ctrl_unpack/_pack,grdchk_main at 
+    beginning/end of adjoint integration is accounted for.
+  The current changes apply to TAF-1.4.26.
+  TAF has one remaining bug, requiring one manual change
+  (see MITgcm manual).
+o cal: synchronized between MAIN and ecco-branch
+
 checkpoint48i_post
 o Changes to restore differentiability of code w.r.t. previous tag
   (mostly adding new routines to make list and replacing
