 ### Removed
 - Swift-based configuration file support removed in favor of YAML-based configuration. All features supported via the Swift file still supported via YAML file. See README.md for more details. Parameters were not renamed to keep migration simple.

-- Support for Swift versions below 5.5 was dropped to make use of the latest improvements in concurrency & SwiftPM plugin system. Use version `0.8.2` if you need to stay on lower Swift versions.

 ### Fixed
 - Issues with paths due to Swift scripting not being as easy to use now fixed by moving over to YAML-based configuration. For custom scripts, responsibility is moved to the user side by allowing to specify the exact command to run.
