     Notes on tags used in MITgcmUV
     ==============================
 
+checkpoint26
+ o moved some #ifdef in optional routines to encompass everything
+   except the argument declarations. This was using up some memory.
+ o fixed macros like _ADT to work with both versions of Linux cpp
+ o cleaned up some unused and uninitialized variables
+   (helps when debugging with strict compile options)
+ o split up CPP_EEOPTIONS.h into options and macros
+   (macros are now in eesupp/inc/CPP_EEMACROS.h)
+ o patch for 2 processor JAM mode
+
+checkpoint25
+ o updates for OBCs and NH
+ o dramatically reduced memory usage
+ o added "JAM" routines for use on Artic network
+ o parameterization of convection by implicit vertical diffusion
+ o added a diagnostic of convective index
+ o moved call to calc_divg_hat() from dynamics() to solve_for_pressure()
+   (this is was partly for OBCs and NH but also in anticipation of
+    an explicit free-surface option)
+ o initial state input files for U and V
+
+checkpoint24
+ o Removed some spurious "REAL"s
+ o Updated KPP to latest version from JPL
+ o Added a COS(latitude) in horizontal viscosity
+
+checkpoint23
+ o Added del^4 diffusion for salt and temperature
+ o Multiple minor fixes (implicit none's, arguments to global_sum, etc.)
+
 checkpoint22
  o Made many small changes: implicit none, format(i5), etc...
  o Introduced KPP mixing scheme (compiles and runs but *not* tested)
