The latest version of ChiantiPy is 0.9.1 and is compatible with CHIANTI database version 9.0. It is not compatible with previous versions

ChiantiPy v0.9.1 is released under the OSI approved ISC license. From Wikipedia: The ISC license is a permissive free software license written by the Internet Software Consortium (ISC). It is functionally equivalent to the simplified BSD and MIT/Expat licenses, …

CHIANTI consists of a database of atomic data that can be used to interpret spectral lines and continua emitted from high-temperature, optically-thin astrophysical sources.

CHIANTI is developed and maintained by scientists at George Mason University (USA), the University of Michigan (USA), and the University of Cambridge (UK). The first version of CHIANTI was released in 1997 and version 9.0 in 2019.
