- Now `northern_hemisphere_results_only` becomes an input argument for `QGField`. Please initialize this when creating `QGField` object and remove this argument from the methods (`compute_reference_states` and `compute_lwa_and_barotropic_fluxes`).
- `eq_boundary_index` is now an input arguemnt merely for `QGFieldNHN22`, but not `QGFieldNH18`. Remove it if you are using `QGField`/`QGFieldNH18`. You can refer to the jupyter notebook examples for the updated usage.
