* The SAFT-gamma-Mie database has been updated to include recent parameters of the following articles: [Febra et al. (2021)](https://doi.org/10.1016/j.fluid.2021.113002), [Wehbe et al. (2022)](https://doi.org/10.1080/00268976.2023.2197712), [Perdomo et al. (2023)](https://doi.org/10.1016/j.fluid.2022.113635), [Valsecchi et al. (2024)](https://doi.org/10.1016/j.fluid.2023.113952) and [Bernet et al. (2024)](https://doi.org/10.1021/acs.jced.3c00358).
* The SAFT-gamma-Mie database now includes a `author_key` and `doi` to identify where the parameters come from.
* The `bubbleTy` and `bubblePy` functions now include an attribute `not_in_y_list` in which the user can provide the index (or indices) of a compononent not present in the vapor phase. This is useful is there are very heavy non-volatile components in a mixture.
* The `dewTx` and `dewPx` functions now include an attribute `not_in_x_list` in which the user can provide the index (or indices) of a compononent not present in the liquid phase. This is useful is there are light non-condensables components in a mixture.
* The `flash` function now includes the attributes `not_in_x_list` and `not_in_y_list`, where the user can provide the indices of the components not present in the phase `x` or `y`. This is useful in VLE if there are non-volatile/non-condensables components in the mixture.
* The `flash` function now allows choosing between two minimization approaches: `gibbs` or `helmholtz`. The new `helmholtz` minimizes the Gibbs free energy using a Helmholtz approach. See [Nagaranjan et al. (1991)](https://doi.org/10.1016/0378-3812(91)80011-J) for further details.
* `saftgammamie` and `saftvrmie` EoS now include the method `association_solver` and `association_check` to compute and to check the non-bonded sites results.
