    35 __If key_bdy and key_tide are not activated, modifications do not change either answers or results of standard configurations__. Thus results changes only concern AMM12 standard configuration. These changes only come from the completely different tidal module implemented. Thus, there are not induced by the modifications of bdy package alone as long as the same options are used. Keeping new and previous tidal modules would have make the code and namelist interface much heavier so that we preferred to just keep the new one.

    3737Note that some issues with overlapping analytical segments have been fixed in bdy package. It is now possible to obtain identical results with user defined "analytical" open boundary segments bounding the domain (ie identical to the case where a single unstructured segment is read from a netcdf file). As a consequence, diagnostics in AMM12 change although no change in the diagnostics themselves has been introduced. 
     
    5555   * nambdy: Add new options for bdy: Flags and times cales to apply relaxation on tracers and baroclinic velocities. 
    5656   * nambdy_index: Simplify definition of analytical segments. 
     57   * namsbc_apr: Flag to add inverse barometer at open boundaries. Options to set reference pressure to a constant value or to the domain average. 
    5758 * About compiler options: Code update does not require any change in compiler options. Yet, we noticed that results are not reproductible unless the lowest level of optimization is used.
