Version v2.56f (November 2020)

New atomic data for elements F,Na,Al,P,K,Cl,Sc,T,V,Cr,Mn,Co,Cu,Zn based on calculations described in Mendoza et al., 2018 A&A...616A..62M and its antecedents. This results in a significant increase in the size of the atomic database and the associated data structures.

Inclusion of free-free heating and opacity. This can affect the temperature significantly, particularly at high density. The free-free heating rate is weighted toward low energy photons, so the flux at the lowest energies in the illuminating spectrum can strongly affect model results.

Large scale switch from static memory to dynamically allocated memory in order to account for the growth of the data structures associated with the atomic database.

Major restructuring and renaming of subroutines to better describe their functionality.
