v0.7.0

Added

• Added SAFT-VR Mie equation of state. #237
• Added ePC-SAFT equation of state. #229

Changed

• Updated model implementations to account for the removal of trait objects for Helmholtz energy contributions and the de Broglie in feos-core. #226

v0.6.0

Added

• Added EquationOfState.ideal_gas() to initialize an equation of state that only consists of an ideal gas contribution. #204
• Added PureRecord, SegmentRecord, Identifier, and IdentifierOption to feos.ideal_gas. #205
• Added implementation of the Joback ideal gas model that was previously part of feos-core. #204

v0.5.1

• Python only: Release the changes introduced in feos-core 0.5.1.

v0.5.0

Added

• Added IdealGasModel enum that collects all implementors of the IdealGas trait. #158
• Added feos.ideal_gas module in Python from which (currently) Joback and JobackParameters are available. #158

• Added derive for EntropyScaling for SAFT-VRQ Mie to ResidualModel and adjusted parameter initialization. #179

Changed

• Changed the internal implementation of the association contribution to accomodate more general association schemes. #150
• To comply with the new association implementation, the default values of na and nb are now 0 rather than 1. Parameter files have been adapted accordingly. #150

• Adjusted all models' implementation of the Parameter trait which now requires Results in some methods. #161
• Renamed EosVariant to ResidualModel. #158
• Added methods to add an ideal gas contribution to an initialized equation of state object in Python. #158

• 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
• Removed generics for units in all structs and traits in favor of static SI units. #115

Packaging
