     Notes on tags used in MITgcmUV
     ==============================
 
+o seaice pkg: add a cpp-flag to include a simple formula for a salinity
+  depend freezing point of sea water at the surface
+o AIM pkg: change threshold on large-scale condensation to conserve Heat.
+   update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
+   and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
+o pkg/diagnostics: add options and parameters for regional-statistics 
+   diagnostics ; define regions by reading a region-mask from a file 
+   (might add other options later)
+o pkg/bulk_force:
+ - add option and parameters to use AIM surface-flux formulae.
+ - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
+   others forcing fields (defined in PARM05, parameter file "data") are loaded 
+   from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
+ - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F 
+ - use the right EXCH call for uwind,vwind (to work on CS-grid).
+ - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
+   and parameters (note: calcWindStress replaces .NOT.readwindstress).
+ - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
+
+checkpoint58
+o add "--embed-source" option to genmake2 which, when the supporting 
+  tools can be compiled (as determined by genmake2) will turn on the 
+  embed_files package which then embeds the entire MITgcm source code 
+  (*.[fFhc] + Makefile) used for the build within the executable
+  - requested by CNH but off by default
+  - adds a paltry <9MB to the mitgcmuv executable in most cases
+  - only writes the output when useEMBEDSRC in eedata is true
+o clean up 3-dim. relaxation codes:
+  * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
+  * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
+  * Thanks to Tom Haine for testing!
+
+checkpoint57z_post
+o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
+  affects output (@ truncation level) of exp. plume_on_slope ; updated.
+o fix the pickup behavior for obcs in combination with ptracers
+o fix a bug in ptracers_external_fields_load
+o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
+  affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
+o transfered surface NH pressure to eta field (if exactConserv).
+o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
+     and update lab_sea output.txt file.
+o completing 3-dim. relaxation code: additional term
+     1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
+  in S/R EXTERNAL_FORCING_T (file external_forcing.F)
+  * At compile time, in "EXF_OPTIONS.h" set
+      #define  ALLOW_CLIMTEMP_RELAXATION
+      #define  ALLOW_CLIMSALT_RELAXATION
+  * At runtime in "data", under &PARM03 set (e.g., units in seconds)
+      tauThetaClimRelax3Dim = 15552000.0,
+      tauSaltClimRelax3Dim  = 15552000.0,
+  * 3 cases:
+      1) Use a constant-in-time 3-dim. field
+      2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
+      3) Real-time relax. to time-evolving prescribed field
+o Adding Laplacian-type smoothness constraint on 
+  initial and boundary (forcing) controls (ic, bc)
+  * enable at compile-time via 
+    ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
+  * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
+  * Absolute scale somewhat unclear so far
+  * no area weighting was included since no other cost term does so far
+
+checkpoint57y_post
+First step for a NLFS adjoint
+o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
+o new init. routines for calc_r_star, calc_surf_dr
+o still need to deal with ini_masks_etc
+o testreport seemed happy
+checkpoint57y_pre
+
+o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
 o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
 o add new offset feature to offline pkg (plus minor cleanup)
 o cfc fixes for final year of integration
