Just updated the PR to resolve the conflict.
After the update to the latest HEAD, CI starts complaining about the format, but the issue was not introduced by this PR but earlier added today. Since e428ecf all CI fail.

Can we merge this one now? @jthegedus

I fixed also the CI build brake in the second PR.

No worries. Thanks
