• Søreide–Whitson Equation of State for H2 phase behaviour in the compositional module.
  
• Added functionality for using the hysteresis from co2lab-mit with the TwoPhaseGasWaterModel.
  
• Improved handling of very low mass flow rates in the geothermal WellboreModel.
  
• Functionality for using the Embedded Discrete Fracture Model (EDFM) with Corner-Point grids.
