     Notes on tags used in MITgcmUV
     ==============================
 
+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+    *not* regenerated since they are already out of date and I don't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)
+ o Corrected common blocks when fooling TAMC to produce adjoint I/O
+   in addummy_in_stepping
+ o Updated verification/vero/ (bug fixes in code/, correct pickups in input/)
+ o Enabled "sliced" (xz-,yz-) exchanges, needed for obcs.
+ o Included following packages:
+   cal: calendar
+   exf: external forcing
+   ecco: essential routines to control use of cal, exf
+         (NB: this is not the full ECCO environment)
+ o disabled some packages by default in genmake
+
+checkpoint38
+ o see notes_c37_adj.txt
+ o corrected wrong layer index in external_forcing_t
+ o replaced the_main_loop/forward_step by the_main_loop
+ o removed forceoutput from write_state
+   (replaced criteria for initial/final state)
+ o added runtime flag for pre-C35 pickups: usePickupBeforeC35
+
 checkpoint37
  o mdsio.F routine split and packaged in pkg/mdsio
    (mdsio.F and mdsio_gl.F still exist in eesupp/src but are not
