  -n, --new                               Show only new issues: if there are unstaged changes or untracked files, only those changes are analyzed, else only changes in HEAD~ are analyzed.
                                          It's a super-useful option for integration of golangci-lint into existing large codebase.
                                          It's not practical to fix all existing issues at the moment of integration: much better to not allow issues in new code.
                                          For CI setups, prefer --new-from-rev=HEAD~, as --new can skip linting the current patch if any scripts generate unstaged files before golangci-lint runs.

      --new-from-patch PATH               Show only new issues created in git patch with file path PATH

      --whole-files                       Show issues in any part of update files (requires new-from-rev or new-from-patch)
      --fix                               Fix found issues (if it's supported by the linter)
