Release v3.0.0

This release upgrades X-PSI to be Cython3 compatible and provides many new features and examples, such as UltraNest sampling, Simulation-Based Inference, and reading data and instrument files that are in FITS format. A few deprecated features were also removed. See further details reported in https://xpsi-group.github.io/xpsi/history.html.

Release v2.2.0

Modeling polarized X-ray signals has been implemented and examples added for simulating polarized pulses (Stokes parameters) using a couple of different atmosphere options. Support for polarized likelihood calculation has also been included. In addition, new integrators (with and without polarimetry) have been implemented to allow atmosphere interpolations with 5 parameters to be performed in 2 steps. See further details reported in https://github.com/xpsi-group/xpsi/blob/main/CHANGELOG.rst.
