mkdocs-unused-files-0.1.5

• Added the excluded_files option (#4):
  List of files (relative to dir) which are explicitly excluded. Works in combination with file_types. Defaults to [].
• Added the strict option (#4):
  Elevates the log level to warning. This allows you to use MkDocs' strict flag (mkdocs build -s) to abort a build if unused files exist. Defaults to false.
