     Notes on tags used in MITgcmUV
     ==============================
 
+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
+  - 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
+
+checkpoint52 = ecco_c52_e35
+o after testing adjoints of checkpoint51u_post
+
 checkpoint51u_post
 o this is the post-merge tag of the ecco-branch
   (needs another clean checkout and re-testing)
