     Notes on tags used in MITgcmUV
     ==============================
 
+
+o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
+
+checkpoint58p_post
+o obcs: stop if obcs is used with useCDscheme = .true.
+o shelfice: 
+ - fix a sign error so that no slip at shelfice interface works
+ - remove stop for combination non-hydrostatic code and shelfice. That does 
+   not mean, that the results are correct, but at least they are numerically
+   stable
+o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
+o added adjoint exch routined for all exch*3d* routines
+  and updated flow directives
+
+checkpoint58o_post
+o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
+  remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
+o change controling S/R for writing pickup file (new S/R do_write_pickup)
+  and clean-up reading/writing of pickup files.
+o fix local version of read/write pickup (NH part) in rotating_tank/code
+o simplify EXCH interface:
+ - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
+ - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
+o added the regrid package
+o shelfice: 
+ - add a simple boundary layer scheme to reduce noise
+ - fix the indexing in shelfice_u/v_drag so that there will be actually drag
+
+checkpoint58n_post
+o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to 
+   local variable (not in common block).
+o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass. 
+  - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more); 
+  - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
+    to work with SingleCpuIO.
+o add "_d 0" to real constant of pkg/cfc subroutines ; 
+   update exp. cfc_exemple & tutorial_cfc_offline output files.
+o multi-threading and IO:
+  - all threads call READ_FLD S/R (needed if using SingleCpuIO): 
+    (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
+  - barrier before and after reading.
+  - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
+  - avoid using MDS_WRITELOCAL for LAND pkg output.
+  - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
+    common-block variables ; Allows multi-threading with master-thread IO.
+o change default MAX_NO_THREADS from 32 to 4 ; 
+  and stop cleanly when MAX_NO_THREADS is too small. 
+o add S/R BAR_CHECK to check multi-threaded barrier synchronization
+
+checkpoint58m_post
+o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
+   and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
+o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
+   keep global_ocean.90x40x15 (for AD testing) with former secondary test 
+   (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
+o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
+    add MITgcm_tutorials (= code + all the tutorials)
 o ecco, option to compute cost for total ssh (mean+anom)
 o consistent with addition of ptracer and ssh in pkg/profiles
 o profiles: adding ptracer and ssh
 o testreport: change multi-test output-file name 
   (from output.txt.{name} to output.{name}.txt)
-o profiles: now ok for mutli-threaded case
+o profiles: now ok for mutli-tiles case
 o seaice: add 4 parameters for different advection schemes for area, 
   (effective) seaice thickness, enthalphy, and snow height. Their default
   is the standard parameter SEAICEadvScheme
