     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.
+
+checkpoint57s_post
+o Add clearing-house for viscosity calculations, mom_calc_visc and 
+  correct numerous bugs in LeithD and Smagorinsky discretizations.  
+  mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be 
+  used simultaneously, and to be used in mom_vecinv and mom_fluxform. 
+  Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
+  and with Strain-Tension viscous term calculation (mom_hdissip.F).  
+  The Strain-Tension form is now called with useStrainTensonVisc=.true.
+  ViscAhStrain and viscAhTension are now retired.
+o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
+o In response to JMC's bug report, genmake2 now ignores any soft-links
+  that it finds in the *current* directory when searching for files.
+  Soft-links found in any other source directories will still work as
+  they did before.
+o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls 
+  a C routine to unlimit the stack size
+o mnc-ify pkg/aim snapshot vars
+o mnc-ify pkg/land as requested by Daniel
+o various changes to mnc including:
+  - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
+  - output can now be grouped so that all files within a group 
+      change the ITER portion of their names in lock-step together
+  - can now read ("global") PER-FACE (in addition to PER-TILE) files
+      and works with both EXCH1 and EXCH2 (but needs more testing)
+  - writing works for all verification test cases w/ g77 on Linux
+
+checkpoint57r_post
+o make MNC variable initialization happen earlier
+o add diagnostics for (almost) each term of the momentum Eq.
+o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
 o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
 o remove MINIMAL_TAVE_OUTPUT option ; 
   add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
 o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
   allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
+o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
+o add time-dependent SST, SSS control
+o cost terms in ecco/ modularized (new cost_generic.F)
+o cost_averages routines are modularized (new cost_averagesgeneric.F)
+o new infrastructure for seaice model vs. obs misfits in seaice/
+  * driver from the_main_loop.F is seaice_cost_driver.F
+  * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
+  * gradient check in Exp. 6a of natl_box_adjoint/
+o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
+  (see README file)
 
 checkpoint57q_post
 o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
