     8The new release 3.4 of NEMO is now available. 
     10Note this is a major release and the documentation has been updated in consequence. 
     12== Major improvements 
     14=== New physics and numerics 
     16* New pressure gradient suitable for s-coordinate (namelist ln_hpg_djc) 
     17* Completion of Griffies iso-neutral diffusion (ln_traldf_grif) 
     18* Back to a semi-implicit bottom friction (bugfree) (namelist ln_bfrimp) 
     19* Add Pacanowski-Philander scheme for computation of Ekman depth in zdfri 
     20* Add a new bulk formulae (namelist ln_blk_mfs and &namsbc_mfs) 
     21* Introduce a drag coefficient compute by wave model (new namelist &namsbc_wave) 
     22* Add tidal potential forcing (new namelist &nam_tide) 
     23* Neptune effect parametrization 
     24* Point to point MPI communication for north fold (namelist ln_nnogather) 
     25* Allow sub timestepping for biogeochemistry models when using non-linear free surface 
     26* Improvement in PISCES (light limitation ; quota model for iron ; use Pa in gas exchange ; fldread for all data ; calcite dissolution & calcon salinity dependence) 
     28=== Configurations, diagnostics and tools 
     30* Suppression of POMME configuration 
     31* Addition of a regional configuration AMM12 (key_amm_12km and [ input files]) 
     32* Improvement of format for lagrangian floats 
     33* Online computing of transport across sections 
     34* Tidal harmonic analysis (new namelist &nam_diaharm) 
     35* Tools to prepare input files for observation operator 
     36* Timing functionality (namelist ln_timing) 
     38=== System simplification 
     40* Simplification of dynamic allocation 
     41* End of merge TRA/TRA (no more separate 3d arrays for tracers, only 4d) 
     42* Suppression of obsolete hpg options 
     43* More flexible definition of BDY input data 
     44* Simplification of interfaces toward biogeochemical models  
     45* Interface with CICE in coupled mode 
     46* Use of fldread to read/interpolate data for passive tracers and dynamical input data for OFFLINE configurations
