     Notes on tags used in MITgcmUV
     ==============================
 
+o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
+  Needed for high-res. runs with large global files 
+  to be able to limit tapelev size
+o Changed some tests for adjoint:
+  * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
+  * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
+  * global_ocean.90x40x15/ back to default 3-level checkpointing
+
+checkpoint57p_post
+o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
+o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
+  (already the case for some pkgs, including recent MNC_init, e.g. thsice)
+o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
+o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
+  (was already the case for dissipation with mom_vecinv,
+   and also the case for grad.PhiHyd when staggered-timeStep)
+  This will allow to put dissipation out-off the AB time-stepping.
+ Unfortunately, affects truncation error. Update output of exp. that "fails"
+  (cg2d matching number) and leave the others for later: front_relax(10),
+  global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
+  matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
+
+checkpoint57o_post
+o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and 
+  (2) its ready to be documented during the 20050801 DocFest
+o MNC-ify the gmredi package -- tested and works w/ and w/o mnc 
+  for ideal_2D_oce and lab_sea on linux_ia32_g77
+o set to #undef CTRL_SET_OLD_MAXCVARS_30
+  in global1x1_tot/code_seaice_adj to access indices 32, 33
+  (worth another tag)
+
+checkpoint57n_post
+o adding precip control xx_precip 32
+o adding swflux control xx_swflux 33
+o Replacing 10 forcing penalty cost routines by 1 generic.
+o Implementing partitioning in time-mean and variable adjustment
+  for atmos. state.
+o Time-mean constant error is now read in data.ecco (instead of hard-coded)
+o in natl_box_adjoint:
+  * updated exp 1 to 10 
+    (but does not have time-mean vs. variable split results yet)
+o updated global1x1/*_seaice_adj/
+  to incorporate latest changes
+o enable useSingleCpuIO for mdsio vector routines
+  (applies in particular to tapelev I/O)
+o removed inefficient K-loop in all active_file*control*.F
+
+checkpoint57m_post
+o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
+  and advect_cs (use EXCH-2 and standard cs-32 grid files).
+o pkg/exch2: filling of face-corner halo regions is optional 
+  (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
+
+checkpoint57l_post
+ tag before updating tutorials (pre-release-2) 
+o add cos & sin of grid-direction orientation angle (curvilinear grid only,
+   for output and interpolation of input fields onto model grid)
+o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
+   Affects results of exp. rotating_tank ; update output.txt.
+o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
+      and taking the square quantity and/or using a fraction-weight field.
+o fix aim_diagnostics_init.F mate numbers.
+o add mnc output capability to diagnostics/diagstat and update
+  our cvsignore files for the ACSII output generated
+
+checkpoint57k_post
+o lab_sea now uses diagnostics package and provides a suite of
+  new EXF diagnostics output.
+
+checkpoint57j_post
+o exf
+  * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
+    Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
+    terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
+  * extended diagnostics output
+    - now includes all EXF variables
+    - hs, hl moved to common block
+    - separate S/R for diagnostics, called after ctrl vector is added
+    - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
+    - EXFqnet contains true Qnet (i.e. includes qsw)
+  * updated verif. lab_sea, global_with_exf
+  * Rearranging hflux (exf_mapfields -> exf_getforcing)
+    to ensure that diagnostics sees a true EXFqnet
+o add matlab scripts for CS-grid vectors (in utils/cs_grid)
+o diagnostics pkg: change pointers so that 1 diagnostic can be used
+  several times with different frequencies.
+o mnc-ify the thsice package as requested by Daniel Enderton
+  - the monitor--MNC output needs work
+  - many attributes need to be added (most are currently blank)
+o mnc-ify theaim_v23 package as requested by Daniel Enderton
+  - many attributes need to be added (most are currently blank)
 o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
 o add Sadourny like discretization to the 4th.O vorticity advection scheme
 o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
