     Notes on tags used in MITgcmUV
     ==============================
 
+checkpoint51a_post
+o added code for biogeochemistry package
+  - new pkgs: dic, gchem
+  - new subroutine in ptracers
+o modify code for biogeo packages
+  - in model/src and pkg/ptracers
+
+checkpoint51
+o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
+  - autodiff, ctrl, exf, grdchk, seaice
+  kept separate packages
+  - cost, ecco, obcs
+o updating verification/internal_wave, verification/lab_sea
+  (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
+
+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
+
+checkpoint50e_post
+o make KPP work with PTRACERS
+ - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
+   nearly a copy of kpp_transport_s
+ - there is no analogue to SurfaceTendencyS, so I have to use 
+   gPtr(of the surface layer) instead
+o add a new platform SunFire+mpi (SunFire 15000) to genmake
+checkpoint50e_pre
+
+checkpoint50d_post
+o change kpp output from multiple-record state files to single-record state 
+  files analogous to write_state.F
+o reduce the output frequency of cg3d-related stuff to the monitor frequency, 
+  analogous to the cg2d-related output. 
+o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512, 
+  so that writing to internal file fn (with length 512) fails.
+checkpoint50d_pre
+
+checkpoint50c_post
+o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
 o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
 o add time-average diagnostic of U*V and vertical diffusive flux for theta.
 o bug fixed in convective adjustment diagnostic (multi-tile set-up).
