     Notes on tags used in MITgcmUV
     ==============================
 
+o pkg/seaice: 
+ - remove unused variables in seaice_evp
+ - reduce number of SQRT in seaice_evp and seaice_calc_viscosities
+ - move if-statement out of loop for better vectorization
+o eeset_parms.F, open_copy_data_file.F & ini_parms.F:
+   named file replacing SCRATCH files (for TARGET_BGL & TARGET_CRAYXT):
+   each processor open a different file (a fix from Matt).
+o cg2d:
+   use simple EXCH (overlap size = 1 and ignore corners), like in cg3d.F :
+   this reduces number of EXCH calls by 2 when using exch2.
+   For now, keep previous size array for gc2d_nsa.F to avoid Pb with store 
+   directives and missing simple EXCH (exch_s3d_rx) adjoint code.
+o pkg/thsice: 
+   add code for Near Infra-Red albedo (from Jeff)
+   (turned on with run-time flag: thSIce_calc_albNIR, in data.ice).
+o ini_model_io:
+   move (from packages_readparms.F & initialise_fixed.F) to ini_model_io.F
+   MNC & MONITOR initialisation calls; move MNC calls from {pkg}_readparms.F
+   to {pkg}_init_fixed.F for {pkg}= kpp, seaice & shelfice.
+
+checkpoint61s
+o pkg/exch2 (exch2_rxN_cube*):
+   remove last BARRIER (no need to synchronise after getting data from shared
+   buffer (get) as long as any change to buffer (put,recv) is between BARRIER)
+o change tiling of natl_box (from 2 to 4 tiles) to get it tested with MPI+MTH
+  and generate new output (for the 2 tests) using default rotationPeriod.
+o pkg/exch2:
+  - always call exch2_*_cube, not exch-1 anymore, if useCubedSphereExchange=F
+    (was already the case with AUTODIFF_EXCH2 defined)
+  - add bj in exch2 arrays and S/R.
+  - can now use pkg/exch2 for regular (non CS) set-up; switch test experiment
+    MLAdjust to exch2 (identical results except with MPI -> truncation diff);
+o add pkg/longstep for ptracer timestep a multiple of U/V/T/S timestep
+  - adds deltaT argument to the subroutines TIMESTEP_TRACER DWNSLP_APPLY
+    GAD_ADVECTION GAD_CALC_RHS GAD_IMPLICIT_R GAD_SOM_ADVECT
+  - verification experiment natl_box.longstep
 o build_options: ifort+mpi_aces optfile (following Constantinos advise):
   allow different versions of ifort (8 or 9) and different versions
    of mpi (mpich or mpich2) to be used with the same optfile.
   requires to load a netcdf module and set MPI_INC_DIR (see comments inside
    optfile). Change testing scripts (example_scripts/ACESgrid) accordingly.
+o pkg/seaice: 
+  fix previous modif (3-level field removed) for old-pickup reading 
 
 checkpoint61r
 o pkg/seaice:
