     Notes on tags used in MITgcmUV
     ==============================
 
+o pkg/ecco: replace old ineffective way of penalizing deviations from
+  first guess (of obcs) with code by Matt Mazloff
+o pkg/ctrl: add code that allows the use of ALLOW_OBCS?_CONTROL without 
+  exf/cal
+  - ctrl_init: fix initialisation (computation of diffrec) for obcs-ctrl
+    and handle case of obcs?period == 0
+    Not affected by these changes: There is still an inconsistency in
+    the computation of start/endrec for the obcs variables for ALLOW_CAL 
+    defined (see comment by Menemenlis, 7-Mar-2003)
+  - make S/R ctrl_get_gen_rec return something meaningful even if
+    ALLOW_CAL is not defined
+  - ctrl_getobcs?: simplify code so that it does not need to use 
+                   S/R exf_swapfields
+o testreport:
+   allow to test MPI with different number of processors for each experiment:
+   create file "SIZE.h.mpi" in each build dir.
+   Note: update of "-command" argument not yet implemented.
+o model/src, pkg/autodiff, pkg/ecco, pkg/seaice:
+  alleviate the need for additional 3D tapes when using
+  the non-inear free surface in the adjoint. This is done
+  by adding an 'update' of hfacc etc. to their current 
+  value at the beginning of forward_step.F. 
+o pkg/seaice
+  seaice_lsr: move stress-divergence computations out of outer pseudo-
+  timestepping loop
+o pkg/obcs/obcs_prescribe_read.F: move 'CALL OBCS_EXTERNAL_FIELDS_LOAD'
+  up, so that the calls of the ctrl_* subroutines are really at the end
+  of the routine.
+o pkg/gmredi:
+  allow to specify a 2-D horizontal map and a 1-D vertical profil
+  as scaling factor for Isopycnal diffusivity (Redi) and GM diffusivity.
+o pkg/seaice:
+  move lsr iterations from seaice_dynsolver to seaice_lsr.
+o pkg/seaice:
+  reduce memory footprint of seaice mutldim advection tapes,
+  by using a 2D tape independent of the generic_advdiff ones,
+  and setting GAD_AREA=1 etc. rather than GAD_AREA=101 etc.
+
+checkpoint62q (2010/12/29)
+o model/src:
+  - check horizontal grid-spacing for unset or zero/negative values.
+  - change AD test hs94.1x64x5 to be truly a 2-D set-up.
+o pkg/flt:
+  - use (recent) mdsio S/R MDS_READVEC_LOC instead of local FLT_MDSREADVECTOR
+  - precision of input and output files set according to readBinaryPrec
+    and writeBinaryPrec (previously always 64.b), pickup remains at 64 bits.
+  - initial float position from tiled file was not converted to index space
+    (looks like a bug): fixed to make it similar to initial pos. global file.
+o global_ocean.cs32x15:
+   change SIZE.h of AD set-up to get same tiling as with MPI.
+   Update output_adm, output_adm.thsice (pass@14) & output_adm.seaice (fail@11)
+o model/src:
+   add flag to control printing of domain fields (bathymetry, hFac ...) in
+   ini_mask_etc (call to plot_fieds_xy*).
+o pkg/thsice:
+   if useEXF, some forcing fields are not valid in overlap: fixed by computing
+   over the interior only + apply EXCH at the end (like with SEAICE advection).
+o pkg/mdsio:
+  - add 2 arguments to S/R MDS_PASS_R4/8toRL/S for overlap size of buffer
+    to copy to/from, so that it can be used to replace MDS_PASS_WH_R8toRL/RS.
+  - change barrier call for safe multi-threads access to 3-D shared buffer.
+  - MDS_READ/WRITEVEC_LOC use buffers from MDSIO_BUFF_3D.h (instead of local ones)
+  - replace call to MDS_PASS_WH_R4/8toRL with call to MDS_PASS_R4/8toRL and
+    remove the 4 S/R MDS_PASS_WH_R4/8toRL/S.
+o pkg/flt:
+  - add fourth-order Runge-Kutta integration
+  - add basic exch2 support (only 1 facet supported so far!)
+o pkg/mdsio+rw:
+  new S/R to read local (or tile independent) vector (read counterpart of
+   mds_writevec_loc, and front-end write_glvec_rl/rs).
+o global_ocean.cs32x15: additional input_ad.seaice experiment
+    that uses pkg/seaice rather than pkg/thsice.
+    (using multidim advection for seaice)
+o towards more F95 syntax for array specification in namelist:
+  - change "data.diagnostics" (data.ptracers was changed before checkpoint62p)
+    of all verification experiments.
+       e.g.:    line: fields(1,3)='ETAN    ','ETANSQ  ',
+      was changed to: fields(1:2,3)='ETAN    ','ETANSQ  ',
+  - finish adding "-DNML_EXTENDED_F77" to DEFINES list in pgf77 and g77 optfiles
+o global_ocean.cs32x15: additional input.seaice experiment
+    that uses pkg/seaice rather than pkg/thsice.
+
+checkpoint62p (2010/12/17)
+o pkg/thsice: rename (ad tape index) iicekey as ticekey, and move it
+    to THSICE_SIZE.h to avoid conflict with pkg/seaice.
+o pkg/seaice: add seaice_diffusion.f seaice_map_thsice.f to adjoint.
+    allow for use of multim. advection in seaice adjoint.
 o pkg/seaice: add diagnostics for snow precipitation and sublimation flux
   - first attempt to close budgets by taking into account the freshwater
-    flux implied by the sublimation of snow and ice. So far only the 
+    flux implied by the sublimation of snow and ice. So far only the
     volume budget is closed, turn on with soon-to-be-retired-again CPP-Flag
     SEAICE_ADD_SUBLIMATION_TO_FWBUDGET
