• [x] All my commits include DCO.
  DCO stands for Developer Certificate of Origin and it is your declaration that your contribution is correctly attributed and licensed. Please read more about how to attach DCO to your commits here (spoiler alert: in most cases it is as simple as using -s option when doing git commit).
  Please be aware that commits without DCO will cause failure of PR CI workflow and can not be merged.
