• Added SAFT-VRQ Mie equation of state and Helmholtz energy functional for first order Feynman-Hibbs corrected Mie fluids. #79
• Added estimator module to documentation. #86
• Added benchmarks for the evaluation of the Helmholtz energy and some properties of the State object for PC-SAFT. #89
• The Python class StateVec is exposed in both the feos.eos and feos.dft module. #113
• Added uv-B3-theory and additional optional argument virial_order to uvtheory constructor to enable uv-B3. #98

• Export EosVariant and FunctionalVariant directly in the crate root instead of their own modules. #62
• Changed constructors VaporPressure::new and DataSet.vapor_pressure (Python) to take a new optional argument critical_temperature. #86
• The limitations of the homo gc method for PC-SAFT are enforced more strictly. #88

• Major restructuring of the entire feos project. All individual models are reunited in the feos crate. feos-core and feos-dft still live as individual crates within the feos workspace.

• Fixed a bug due to which the default ideal gas contribution was used for every equation of state. #17

• Added gc-PC-SAFT equation of state and Helmholtz energy functional.
• Added PeTS equation of state and Helmholtz energy functional.
• Added UV-Theory equation of state for Mie fluids.

• Combined all equations of state into a single Python class EquationOfState and all Helmholtz energy functionals into the Python class HelmholtzEnergyFunctional. #11

• Updated quantity to 0.5.0.
• Updated feos-core to 0.2.0.
• Updated feos-dft to 0.2.0.
• Updated feos-pcsaft to 0.2.0.

• Added pyproject.toml. #8
• Fixed modules of SI classes to make them pickleable. #8

• Updated feos-core to 0.1.5.
• Updated feos-dft to 0.1.3.

• Initial release
