     Notes on tags used in MITgcmUV
     ==============================
 
+checkpoint40
+o all changes of checkpoint40pre?
+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+    *not* regenerated since they are already out of date and I don't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.
