     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
+

 o Adding eddy stress controls a la Ferreira et al.
