     Notes on tags used in MITgcmUV
     ==============================
 
+checkpoint46b_post
+o Added new equation of state -> JMD95Z and JMD95P
+  - EOS of Jackett and McDougall, 1995, JPO
+  - moved all EOS parameters into EOS.h
+  - new routines ini_eos.F, store_pressure.F
+o Added UNESCO EOS, but not recommended because it requires 
+  in-situ temperature (see JMD95)
+o Modified formatting for knudsen2.f in utils/knudsen2 and added
+  unesco.f to be used with POLY3
+checkpoint46b_pre
+
+checkpoint46a_post
+o Added (atmospheric) pressure loading
+  - new field in FFIELDS.h, etc...
+  - new cpp flag ATMOSPHERIC_LOADING
+o Changed hFacC to _hFacC in calc_phi_hyd.F
+o Added SHORTWAVE_HEATING to some files for consistency
+checkpoint46a_pre
+
+checkpoint46
+further merges from release1_p5
+o new ctrl package
+  - adopted from ECCO environment to enable optimization
+  - added Eliassen Palm fluxes to controls
+o added Eliassen Palm flux controls to gradient check package
+o cost package
+  - Compatible with new ctrl package
+  - added Eliassen Palm cost hooks
+  - modif's of existing cost functions
+o Adjoint-related bug fixes in kpp:
+  - kpp_calc: sore of kpphbl avoids recomputation/call to S/R kppmix
+  - kpp_routines: store of Rib avoids partial recomputation bug of TAF.
+o autodiff package
+  - flow directives:
+    + new for S/R do_the_model_io
+    + enhanced for S/R checkpoint
+    + new gmredi.flow
+  - Introduced CPP option ALLOW_AUTODIFF_MONITOR to
+    disable adcommon.h/g_common.h by default.
+  - fixed problem for adjoint of global_max
+o modified verification/carbon/
+o New setup for adjoint of global_ocean
+o added hooks for Eliassen Palm fluxes (dynamics.F, ini_fields.F)
+o cleaned TAF keys iikey, idkey (dynamics.F, thermodynamics.F)
+o incorporated hooks for sponge layer code (external_forcing.F)
+
+checkpoint45d_post
+o import 2 fixes from release1_p5 (CG2D.h & packages_readparms.F)
+o use recip_dx*,recip_dy* instead of /dx*,/dy* in orlanski_E,W,N,S
+  (affects plume_on_slope "cg2d" output)
+o add new parameter deltaTfreesurf for free-surface time stepping
+o exchange gT,gS when using staggerTimeStep & GM & Oly<4 
+o NONLIN_FRSURF: rescale gNm1 to get a better conservation with A-B
+o change phiMin in exp1 (to agree with documentation)
+o add new flags: 
+ - T,S forcing inside/outside Adams-Bashforth
+ - turn off temp,salt advection and/or forcing
+ - for each tracer, define internal flag for multiDimAdvection & A-B
+o monitor: change definition of KE to check conservation of Energy
+
+checkpoint45c_post
+o Removed f90 comments ("!")
+o Modified initialisations to enable exf package for MITgcm
+  (without invoking ECCO_PACKAGE).
+o modifications to gradient check package (Martin Losch)
+  - enable centered differences
+  - modified format of standard output
+
+checkpoint45b_post
+o cleaned exchange calls in cg2d
+o Included CPP option ALLOW_AUTODIFF_MONITOR in forward_step
+o included CPP option SINGLE_LAYER_MODE in thermodynamics
+  to configure barotropic setup (Martin Losch)
+o moved some initialisations within bi,bj loop in dynamics
+  (TAF flow dependency)
+o in initialise_varia, moved call packages_init_variables
+  before convective_adjustment_init
+  (corresponding adjustment of TAF tape initialisation).
+o in calc_diffusivity/calc_viscosity extended domain to full overlap.
+
+checkpoint45a_post
+o compute Rho over the whole domain (extend iMin,jMin indices)
+o specific exchange for X-slice domain (case Ny=1)
+o argument futureIter of S/R obcs_calc missing in exp4 & internal_wave /code
+o solve_for_pressure : set cg2d_x to zero where OBCS are applied
+
+checkpoint44h_post = checkpoint45
+o Fix to restore differentiability:
+  place at which packages_init_variables is called in
+  initialise_varia is crucial for reverse control flow.
+o modifications in GMRedi to enable stable adjoint
+  (corresponding modif's in thermodynamics, dynamics)
+o added missing hook for sponge layer code in external_forcing
+o modified test cost functions
+o storing in gad_advection (plus removal of write(0,*)!
+o missing headers TR1.h added in convective_adjustment routines
+o errorMessageUnit set non-equal zero in eeboot
+  (conflict on some platforms, e.g. IBM SP3)
+o modified carbon verif.
+
+checkpoint44h_pre
+o vertical grid option: allow to put the Interface at the middle between
+  2 cell-centers ; replace delZ in pkg/kpp by drF.
+o GM Advective form: Tracers are advected using the residual transport (=
+  Euler+GM-bolus); set param GM_AdvSeparate=T to return to previous form.
+
 checkpoint44g_post
 o fix surface correction term in multiDimAdvection (affects plume_on_slope 
   results) ; ifdef missing in thermodynamics.F
