This pages lists major changes and additions to Korg since the publication of the code paper. For a more detailed changelog, see the github releases.

• 0.23.0 fixed a normalization problem in Bracket line profiles which also effects HLINOP and Synspec.

• 0.20.0 introduced code to fit to observational spectra.

• 0.19.0 added Bracket lines.

• 0.18.2 upgraded the equation of state solver to self-consistently solve for the electron number density, rather than assuming the value in the model atmosphere.

• 0.18.1 made it possible to synthesize in multiple wavelength windows simultaneously with little overhead.

• 0.18.0 introduced a parser for turbospectrum-format linelists. See read_linelist for details.

• 0.17.0 introduced the use of the Mihalas-Daeppen-Hummer formalism to account for plasma effects when calculating Hydrogen lines and H I bound-free absorption.

• 0.15.0 added 28 new polyatomic molecules from exomol to the equilibrium calculations.

• 0.14.0 introduced a built-in model atmosphere interpolator, based on the SDSS MARCS grid. See interpolate_marcs.

• 0.10.0 is the version of Korg described by the code paper.
