This log gives an overview of the most prominent changes in each release. Minor fixes, changes “under the hood” and refactoring changes are not listed here. While we were rather sloppy with the versioning in the past, we follow the Semantic Versioning scheme and the guidelines from “Keep a Changelog” since 2019.
