     Notes on tags used in MITgcmUV
     ==============================
 
+checkpoint53
+o stable checkpoint with up to date adjoint
+  TLM tests only run for 1st grdchk at the moment. Its unclear if
+  this is a code problem or a problem with resetting code for g_
+  variables that is being autogenerated wrong.
+  Otherwise:
+   o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix. 
+   o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ) 
+     are both still in chaos following their security messes.
+
+checkpoint52n_post
+o various build (mostly genmake2) changes including:
+  - ability to build/run more easily within Cygwin and MacOS X
+  - more complicated Makefiles with a stronger dependence on Gnu Make
+o pkg/seaice modifications
+  - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
+    of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
+    and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
+  - changed proxy for geostrophic velocity and updated 
+    verification/lab_sea/results/* accordingly
+  - removed ADI dynamic solver from pkg/seaice
+  - replaced all occurrences of 1/CSTICE or 1/CSUICE
+    they caused a segmentation fault under certain circumstances
+  - removed unused field WATR
+o bug fix in exf-package:
+  -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
+     now reflect that.
+o small fixes in the cal-package:
+  - set reference date to first of January for the 'model'-calendar
+  - failing of cal_CheckDate in cal_FullDate now actually results in a
+    warning
+o small modifications in exf-package to increase flexibility:
+  - change climtempfreeze from a constant to a runtime parameter that
+    is specified in data.exf_clim (default = -1.9)
+  - introduce runtime parameter windstressmax (default = 2.0) that is
+    specified in data.exf
+o fix in pkg/thsice:
+  - update Evap (Tsf changes) to be consistent with Latent heat flux
+  - maintain snow precipitation unchanged (even if Tsf >=0).
+ both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
+
+checkpoint52m_post
+o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
+  this does not change any of the results, because myIter=0 in swfrac always
+  lead to jwtype=2 (the default anyway), but the call makes little sense
+  as a default
+o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
+o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
+  atmospheric model (AIM) to use it ; add a "slab ocean" component.
+o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
+o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
+o extending useSingleCpuIO option to work with new exch2 I/O format
+  - old-style, missing-tile I/O is still accessible by defining CPP
+    option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
 o monitor package can write to NetCDF files and/or STDOUT
 o fix re-definition bug in MNC_GRID_INIT_ALL()
 o doc/api_reference added
