     Notes on tags used in MITgcmUV
     ==============================
 
+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 forcing controls 
+  * enable at compile-time via ALLOW_SMOOTH_BOUNDARY_CTRL_COST
+  * enable at run-time via mult_smooth = 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
