     Notes on tags used in MITgcmUV
     ==============================
 
+checkpoint22
+ o Made many small changes: implicit none, format(i5), etc...
+ o Introduced KPP mixing scheme (compiles and runs but *not* tested)
+
+checkpoint21
+ o Introduced new I/O package that supports direct-access records (mdsio.F)
+ o Split-up mid-level I/O routines
+ o Updated input data for experiments 0,1,2,4 and 5
+ o Finally removed the genmake.* scripts (everyone seems happy with genmake)
+
+checkpoint20
+ o Tidied up open-boundaries some more
+ o Added non-hydrostatic code
+ o Fixed some input data
+ o Modified MPI start-up to work in "coupled" context.
+
+checkpoint19
+ o Tidied up directory structure for verification experiments.
+ o Added new code for open boundaries.
+ o Corrected advective terms near boundaries.
+ o Added CPP flag for "old UV" geometry and corrected spherical geometry.
+ o Implemented free-slip/no-slip BCs and del^4 dissipation.
+ o Split default parameters out of ini_parms.F into set_defaults.F.
+
+checkpoint18
+ o Further changes for optional code generation with 
+   CPP - ugh!
+
+checkpoint17
+ o Beginning to incorporating modularity
+   for supporting atmos. and ocean configs.
+ o Small changes for TAMC complinace
+ o New ultra simple test case. Barotropic box
+   configuration "exp0".
+
+checkpoint16
+ o Minor changes to exchange routines to support 
+   accumulation in reverse mode. Adjoint of an
+   assignment is an addition.
+ o Changes to support compilation by TAMC (LR(1) 
+   syntax) and by g77 under Linux ( 72 character
+   limit ).
+
 checkpoint15
  Rewrote exchange routines to allow
  o General tile <-> tile connectivity.
