     Notes on tags used in MITgcmUV
     ==============================
 
+o add saltFlux(+File) forcing capability with periodicExternalForcing
+o allow to use pkg diagnostics for GM-Redi & ThSIce output
+o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
+o improvements for the MNC output from DIAGNOSTICS:
+  - correct handling of the unlimitied dimension
+  - all dims now have associated coordinate variables
+  - variables located at U, V, and Corner ("Z") points are now written
+    with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that 
+    *all* data points are output
+o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
+o added pkg/seaice/seaice_monitor.F
+o mdsio_readfield.F can now read files visible only to master MPI process.
+o pkg/seaice: some test code for ice-modified ocean stress
+o exf_getffields interpolation defaults to bilinear for all scalar forcing
+  fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
+  spurious negative numbers for precipitation and humidity.  Will cause
+  some small numerical differences for integrations using pkg/exf/exf_interp.F.
+o pkg/ctrl/
+  * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
+    May be enabled via doPackDiag
+  *  introduce z-scaling of 
+     + gradient (doZscalePack) and 
+     + control (doZscaleUnpack)
+o pkg/mdsio/
+  * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
+  * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
+
+checkpoint57b_post
+o simplify options in diagnostics_fill arguments (remove weird combinations)
 o fix MNC coordinate variables so that they now contain per-face index
   values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in 
   general, EXCH2 grids are only aligned to a "local" coordinate system
