     Notes on tags used in MITgcmUV
     ==============================
+
+o CS-grid: fix divergence contribution to Leith viscosity. Affects (@ 
+  truncation level) 4/5 MLAdjust test results (11&12 digits match).
+
+checkpoint57t_post
+o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
+o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
+  same truncation, independent of the face number: affects affects several
+  test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
+o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
+  note that biharmonic viscosity + no-slip was not tested in any experiment.
+o fix bug in non-linear free-surf side-drag ; generate new output for
+  global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
+o make mnc honor the writeBinaryPrec flag for most kinds of output
+o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
+o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
+  error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
+o add brackets in multi-terms sum to get same truncation, independent of
+  the face number (manage to get exactly same value of gU,gV at the cs-edge)
+  affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
+o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
+  and viscA4Remax, which allow one to limit the minimum viscosity by specifying
+  a maximum grid-scale Reynolds number.  Also, changes all length calculations
+  in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
+  Suggested values of viscosity parameters found in mom_calc_visc. 
+  Many new viscosity diagnostics available.

 o Add clearing-house for viscosity calculations, mom_calc_visc and 
   correct numerous bugs in LeithD and Smagorinsky discretizations.

   The Strain-Tension form is now called with useStrainTensonVisc=.true.
   ViscAhStrain and viscAhTension are now retired.
