 - Having a two-dimensional list makes processing flexible. For example, one can flatten (and uniquify) the list to get changed files from all commits which were traced back. Or one can use `changed_files[0]` to get changed files from the latest commit. One might also use the output of `backtrack_count` from [`paths_result`](#paths_result) to process the list of changed files.
 - Returns information only if one of the options [`paths_ignore`](#paths_ignore), [`paths`](#paths), [`paths_filter`](#paths_filter) is set.

 You can use `skip-duplicate-actions` to either skip individual steps or entire jobs.
 To minimize changes to existing jobs, it is often easier to skip entire jobs.
