     Notes on tags used in MITgcmUV
     ==============================
 
+o pkg/layers:
+  - Added missing call to layers_fill for keeping track of tottend in
+    pkg/diagnostics/diagnostics_fill_state.F
+o pkg/layers:
+  - added CPP flux LAYERS_FINEGRID_DIAPYCNAL to disable fine-grid binning
+    of diapycnal fluxes
+o pkg/layers:
+  - reverted changes to interpolation to previous treatment; there
+    was never actually a problem
+o pkg/layers:
+  - fix interpolation of layers tracers in the presence of partial cells
+  - add lots of new functionality to compute water mass transformation
+    (enabled by CPP flag LAYERS_THERMODYNAMICS)
+  - add new calls from main code (diags_oceanic_surf_flux.F,
+    thermodynamics.F, impldiff.F) and gad to save the necessary fields
+    for layers_thermodynamics calculations
+o pkg/ptracers:
+  - add capability of stepping a passive tracer forward 
+    without advection by setting PTRACERS_advScheme to 0.
+o pkg/diagnostics:
+  - add few (threads) _BARRIER around any update of "diag_pkgStatus".
+o pkg/layers:
+  - shift potential density field "prho" by -1000 for density layer averaging so
+    that it corresponds to usual "sigma" definition (i.e., rho(p=const)-1000);
+    Note that density bin boundaries (layers_bounds in data.layers) have
+    to be set accordingly (i.e., shifted, in sigma scale).
+o pkg/layers:
+  - fix snap-shot output of layer thickness @ V.pt and output of pot.density
+  - fix calculation of layer non-weighted velocity and layer probability
+  - add diagnostics for pot.density used for layer averaging
+o pkg/seaice:
+  - seaice_calc_viscosity.F: change computation of deltaC**2 to ensure
+    positiveness, modify a few comments and improve variable names,
+  - the changed computation of deltaC affects most seaice-related
+    experiments at the truncation level.
+    seaice_itd.thermo is affected by far the most, with
+    only 7 digits of agreement remaining; update experiments.
+
+checkpoint65l (2015/05/04)
+o pkg/shelfice:
+  - in shelfice_thermodynamics.F, if SHELFICEBoundaryLayer=.true., then set
+    factor drKp1 to zero where it is negative (ie. do not use
+    SHELFICEBoundaryLayer if hFacC>1)
+  - the same for factor drLoc in shelfice_forcing.F
+o tools/genmake2: move FEXTRAFLAGS from FFLAGS to FOPTIM to avoid a problem
+    with modules in ptracers, when using testreport option "-small_f"
+o pkg/seaice/seaice_growth.F (in case of SEAICE_ITD)
+  - replace tmpscal1**1.36 by faster exp(1.36*log(tmpscal1))
 o verification/testreport
   - add new option -small_f
     with this option testreport first makes the target small_f (*.f files)
-    before running make (all). This is useful for explicit inlining when 
+    before running make (all). This is useful for explicit inlining when
     all sources need to be full available.
+o pkg/exf/exf_interp.F:
+    remove previous changes related to reverse (decreasing) input grids latitude
