CHIANTI consists of a critically evaluated set of up-to-date atomic data, together with user-friendly programs written in Interactive Data Language (IDL) and Python to calculate the spectra from astrophysical plasmas. The CHIANTI package is freely available. If you use the package, we only ask you to appropriately acknowledge CHIANTI .
- The Chianti wine-producing area of Tuscany, Italy -	Version 11.0.4 of the CHIANTI IDL routines released, June 2026 This minor update to the CHIANTI IDL routines fixes a bug in the two_photon continuum routine in the case where the ioneq file contains a single temperature. Also, duplicate code for the DR suppression formula has been consolidated to a single routine (ch_dr_suppress). Solarsoft users should update their distribution, otherwise the CHIANTI IDL routines can be downloaded from our download page.
We are grateful to individual scientists and funding agencies for their support.
