Changelog
==========

May 2024 - Version 0.4.0

* Switch to ROOT 6.30, supporting now RHEL8 and RHEL9.
* Introduced support for ML inference via `OnnxRuntime`. A generic producer is available at this link: https://github.com/KIT-CMS/CROWN/blob/main/include/ml.hxx
* Introduced a CorrectionManager that is responsible for loading correction files and sharing them across producers. This allows to load the corrections only once and share them among the different producers, resulting in a significant speedup of the initial loading time. As part of this implementation, many functions now have a deprecated version, that does not use the `CorrectionManager`. The old functions will be removed in the next major release. A more detailed description can be found on :ref:`The Correction Manager` page.
