     Notes on tags used in MITgcmUV
     ==============================
 
+o r* coordinate added in #ifdef NONLIN_FRSURF block.
+ (modification to pressure gradient not yet implemented)
+o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
+  (for U & V) that are used for vertical advection of momentum.
+
+checkpoint48a_post
+o In preparation for r*, use temp. array to compute vertical transport
+   in flux-form momentum pkg. => change results of few test-exp. 
+  Update output of: exp4, exp5, front_relax, global_ocean_pressure, 
+                    lab_sea, natl_box & plume_on_slope
+
+checkpoint48
+o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
+
+checkpoint47j_post
+o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
+o moved adexch from forward_step to addummy_in_stepping
+o added exch in ctrl_map_...
+o aveFreq.=0. at end of cost_final to avoid overwrite in
+  reverse checkpointing loop
+o Yet more changes in gmredi:
+  * adgmredi_calc_tensor
+    avoiding all recomputation of gmredi_slope_limit
+  * adgmredi_x/y/rtransport
+    added flag for excessive storing to avoid recomp. of
+    u/v/rtans, dTdx/y/z
+    -> this is not really necessary and very memory-consuming
+  * adgmredi_slope_psi:
+    consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
+  * gmredi_slope_limit
+    re-activated full calculation of taperfct for case 'ac02'
+o updating verification/ adjoints of carbon, global_ocean.90x40x15
+
+checkpoint47i_post
+o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
+o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
+  default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
+o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf) 
+o gmredi: fix few bugs.
+
+checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
+This will be a good checkpoint to plug into the ecco-branch.
+o few modif.'s to get latest version adjointed
+  (mainly kick out code in ini_linear_phisurf)
+o modif's to run adjoint with exactConserv
+o case GM_BOLUS_ADVEC should be cleaned
+  S/R gmredi_slope_psi should be cleaned
+o verification/carbon now has exactConserv=.TRUE.
+
 checkpoint47g_post
 o time-average AIM output: becomes independent from statvars time-average
   (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
