     Notes on tags used in MITgcmUV
     ==============================
 
-o modifications to make FREEZE flux visible to pkg/kpp
+o surface flux time-av diagnostic modified for NLFS & RealFreshWater 
+
+checkpoint52c_post
+o Fixing OPTIONS files for use of exf:
+  - ALLOW_ECCO not needed
+  - ECCO_CPPOPTIONS.h should not be included from
+    EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
+    as has been the case in the past
+  - All cal/exf related options are currently set in
+    single header file. Should remain so until we
+    agree on a consistent new policy.
+o Removed all CPP options for cal package.
+  cal has no more CPP options.
+o modified STOREs in GAD_ADVECTION
+o corrected key comp. for passkey
+
+checkpoint52b_post
+o new version: "thsice" of thermodynamic sea-ice pkg:
+ - only 1 call from "forward_step"; conserve energy, fresh-water & salt. 
+ - modify fluxes but do not change theta directly;
+ - light cleaning of bulk_force pkg (still needed with thsice).
+ - add forcing fields + data files in global_ocean.cs32x15/inp_thsice 
+   + output_thsice.txt to test thsice & bulk_force pkgs.
+o put back grid & coriolis monitor output.
+checkpoint52b_pre
+
+o call "do_the_model_io" at the beginning (=> dump initial state) 
+o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
+o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
+  (need info on NUMBER_OF_PTRACERS)
+o missing PTRACERS headers in some routines
+o default tamc.h in pkg/autodiff supposed to crash
+  to ensure proper customization
+
+checkpoint52a_post
+o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
   - moved surfaceTendencyTice from pkg/seaice to main code
-  - FREEZE moved to FORWARD_STEP
-  - subroutine FREEZE now limits only surface temperature
-    this means new output.txt for global_ocean.90x40x15,
-    global_ocean.cs32x15, and global_with_exf, but note
-    that results for these three experiments remain
-    bit-identical to before if allowFreezing=.FALSE.
+  - subroutine FREEZE_SURFACE now limits only surface temperature
+    and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
+    => new output.txt for global_ocean.cs32x15 & global_with_exf
+  - keep the old version of FREEZE for backward compatibility;
+    global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
+  - corresponding modifs for TAF directives
 o added surface flux output variables to TIMEAVE_STATVARS
 o time-averaged output for pkg/ptracers
+o fix problem with ECCO-related divided adjoint
+  snapshot file was missing some ad-variables,
+  but no warning issued by TAF
 
 checkpoint52a_pre
 o some bug fixes for #undef REAL4_IS_SLOW
