     Notes on tags used in MITgcmUV
     ==============================
 
+checkpoint57f_pre
+
+o mnc-ifying the seaice package
+o introduced an alternative length scale calculation for use in the limiting
+  maximum viscosity (off by default, see mom_vi_hdissip.F for details)
+o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
+o added modified Leith scheme with viscosity proportional to grad(Hdiv) 
+  as well as grad(vort3).  Made it compatible with both approximate form
+  for the cubed sphere and full form of these gradients.  Added flag
+  useFullLeith to select between approximate and full form.  
+o add "d0" in getcon.F to reduce differences between compilers/platforms
+  update output.txt of exp. fizhi-gridalt-hs
+o change port_rand funtion to allow to set the seed.
+o fix obscure MNC bug involving conversion between reals and integers
+  - it caused no problems with certain (eg. gcc, ifc) compilers but the 
+    new version is now more standards-compliant
+o adjoint-related modifications
+  * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
+  * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
+  * mom_vi_hdissip: to be able to use Leith scheme in adjoint
+
+checkpoint57e_post
+o Adding eddy stress controls a la Ferreira et al.
+checkpoint57e_pre
+
+o fizhi pkg: fix AtoC and CtoA when called with same input & output array
+  update output.txt of exp. fizhi-gridalt-hs
+o add more "Z" dimensions and associated coordinate vars to MNC
+o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
+o parameter calendarDumps: when set, approximate months (30-31 days) and years
+  (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
+  KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
+  months and years.  Requires pkg/cal.
+o diagnostics: add pickup functionality
+  - off by default for backwards compatibility
+  - current version only uses MDSIO -- MNC will be added
+o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
+o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
+
+checkpoint57d_post
+o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
+o modify verification/ideal_2D_oce so that it tests the creation of mnc 
+  output from the diagnostics package
+o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
+o make genmake2 more portable by using ".$FS" instead of ".f" for more
+  of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
+o add coordinate variables to the MNC output from the diagnostics package
+o change MNC-flags default value: true when useMNC=TRUE
+o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
+  the ability (off by default) to read the grid information using MNC 
+o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
+o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
 o do snap-shot diagnostics at the middle of the time-interval (instead of 
   at the end).
 o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
