     Notes on tags used in MITgcmUV
     ==============================
 
+checkpoint51
+o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
+  - autodiff, ctrl, exf, grdchk, seaice
+  kept separate packages
+  - cost, ecco, obcs
+
+checkpoint50i_post
+o Preparing next differentiable checkpoint and sync
+  of MAIN vs. ecco-branch
+  - 1st step: this one is differentiable
+  - 2nd step: next(! not this) checkpoint will have updated packages 
+              from ecco-branch)
+
+checkpoint50h_post
+o new package "land": provide surface BC for AIM.
+o pkg/ptracers: apply exchange to all tracers after reading a pickup.
+o AIM: use true log-P extrapolation for near surface temp (= as in 
+    F.Molteni paper) ; update aim.5l_cs output.
+o New variable in PARM03 for more flexible pickups
+o somewhat cleaned package initialisation sequence for
+  ctrl/ cost/ ecco/ in packages_... routines
+
+checkpoint50g_post
+o merged with release1_p17 (pkg/seaice and verification/lab_sea)
+  - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
+  - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
+    made the default because of faster convergence than ADI
+
+checkpoint50f_post
+o exf totally restructured
+  - replaced all exf_set_ routines by one generic exf_set_gen.F
+    and made sure it's still differentiable
+  - split exf_getffields.F into new exf_bulkformulae.F
+  - exf_inscal_/exf_outscal_ suffixes consistent with field names
+  - updated adjoint/makefile and relevant verif. accordingly
+
+checkpoint50f_pre
+ o AIM: near surface temp evaluated from Pot.Temp: fixed for Part Cell ;
+      + change Evap over land. (update aim.5l_cs output)
  o added missing .cvsignores and made uniform across expts
  o changed configuration of tidal_basin_2d expt
  o added pkg/debug functions for tracing code in fatal crashes
  o tidied pkg/monitor to use MONITOR_OPTIONS.h
  o new fn in pkg/monitor to stop model if solution grows too big
  o removed lots of single quotes from comments
- o fixed gather/scatter inital MPI dialogue in ini_procs.F
 
 checkpoint50e_post
 o make KPP work with PTRACERS
