     Notes on tags used in MITgcmUV
     ==============================
 
+checkpoint58q_post
+o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
+  1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
+  high_res_cube configuration by 4% on Columbia.
+o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
+  add (in global_with_exf/code) a version of EXF_INTERP_READ without
+  dynamical allocation (seems to work in multi-threaded).
+o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
+  single CPU io) so that TAF does not have to see EESUPPORT.h
+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).
