+**File discovery fixes**:
 
 Finding paths and files to check has been replaced with a new version using ``pathlib`` - this should not result in any changes,
 except fixing an issue where ``pylint`` and ``pydocstyle`` were inspecting the same file or directory twice sometimes.
 However it may cause slightly different orders or reduce these duplicate warnings.
 
-The behaviour of prospector should be unchanged, apart from some bugfixes related to the old file discovery mechanism.
