     Notes on tags used in MITgcmUV
     ==============================
+
+checkpoint41
+o re-formatted/added comments in prologues of key subroutines
+  to work with protex
+
+checkpoint40
+o moved calc_gs, calc_gt and calc_tr1 back to model/src
+o added FLT (floats) package from Arne along with demo. experiment
+o re-arranged Adams-Bashforth scheme for tracers to allow easier
+  implementation of forward-in-time forcing terms
+o more mods for non-linear free-surface including new variable
+o modified multi-dim method to work on cube
+o bug fix in KPP (from DM)
+
+checkpoint40pre9
+o added DST advection schemes
+o fix MPI bug on SGI's
+o modifications for non-linear free-surface
+o fixed conditionals for fixed flow/passive tracer only mode
+o added tension/strain form of stress tensor
+o changes to commenting of arguments for TAF/TAMC
+o added/updated many matlab scripts
+o added multi-dimensional advection method for tracers
+  
+checkpoint40pre8
+o new package rw/
+  Added method for dumping intermediate local arrays:
+  mdsio_writetile - same as mdsio_writefield except works from inside
+                    bi,bj loop
+  mdsio_writelocal - same as mdsio_writetile except works for local
+                     arrays
+  write_local_r? - higher-level wrapper for mdsio_writelocal
+  Controlled by diagFreq. Defaults to zero (ie. no dumps)
+  Example given at end of mom_vecinv.F that dumps some local arrays.
+o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
+  control flux-form versus vector invariant code.
+  Switch is runtime flag vectorInvariantMomentum (defaults to false)
+  or genmake -DISABLE ...
+o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
+  (additional storing is now needed for case vecinv;
+  currently nothing implemented to switch this storing off
+  in case fluxform is used since no CPP flag available).
+
+checkpoint40pre7
+o bug fix in dynamics.F
+  calc_viscosity called before k=1,Nr loop.
+o added some #ifdef's ALLOW_PASSIVE_TRACER
+o cleaned initialisations in ctrl_map_ini
+  related to TAF
+
+checkpoint40pre6
+o split dynamics into thermodynamics & dynamics
+o corresponding split of calc_diffusivity into
+  calc_diffusivity, calc_viscosity
+  (kpp_calc_diff, kpp_calc_visc).
+o Added diffkr, kapgm to control variables
+o bug fix in gmredi_slope_limit for ldd97
+
+checkpoint40pre5
+o proper initialization of Adams-Bashforth time stepping
+  + uses forward step for very first step of model (iter=0)
+o re-generated *all* output since almost all output is modified by this
+  change (sorry but we've been putting this one off for about 2 years)
+  + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
+    *not* regenerated since they are already out of date and I don't
+    want to create the impression that they are suddenly working.
+o removed KAP stuff for DEC's
+o modified/added many .cvsignore files in */code and */input
+o added new expt "solid-body.cs-32x32x1"
+  + this uses an alternative form of ini_curvilinear_grid.F which
+    is not necessarily any better than the current one...
+
+checkpoint40pre4
+o added re-initialisations of utrans,vtrans,rtrans in
+  calc_common_factors which are crucial for TAF.
+o extended iMin,jMin range for calc_common_factors,
+  calc_diffusivity
+o added option ALLOW_PASSIVE_TRACER
+o a few minor updates and fixes
+
+checkpoint40pre3
+o created calc_gtr1.F for gad package
+o split the_main_loop and re-introduced forward_step
+o some recomputations of nIter0 for TAMC
+
+checkpoint40pre2
+o Updated to latest branch of AJA, JMC
+o Added gradient check package
+o Added routines for passive tracer handling
+o Added carbon sequestration sensitivity experiment
+
 checkpoint39
  o Modifications and fixes to support TAMC
    (mainly missing or wrong directives)
