===================
* Add a new category ``gas standard volume`` from quantity ``standard volume``.
* Add transient input for:
- ``MassSourceNode`` and ``MassSourceEquipment``: ``temperature``, ``volumetric_flow_rates_std``, ``mass_flow_rates``, ``total_mass_flow_rate``, ``water_cut``, ``gas_oil_ratio``;
- ``PressureNode`` and ``ReservoirInflowEquipment``: ``pressure``, ``temperature``, ``mass_fractions``, ``volume_fractions``, ``gas_liquid_ratio``, ``gas_oil_ratio``, ``water_cut``;
- ``LinearIPR``: ``well_index``;
- ``HeatSourceEquipment``: ``power``;
* Add two new hooks to calculate solids model (for slurry viscosity and slip velocity).
* **Breaking Change**: Change ``OpeningCurveDescription`` (``opening_curve`` attribute) for ``Curve`` from barril.
* **Breaking Change**: Change signature of ``HOOK_INITIALIZE_STATE_VARIABLES_CALCULATOR``.
* **Breaking Change**: Change signature of ``HOOK_CALCULATE_RELATIVE_EMULSION_VISCOSITY``.
* Add new API function ``get_relative_emulsion_viscosity`` which is a helper function that can be used in the Hooks of Liquid-Liquid Mechanistic Model.
