Hi @pschatzmann.
Your pull request has been detected as something other than a Library Manager submission.
A maintainer will need to review it before it can be merged.

Hello @pschatzmann. I am confirming your request.

Unlike submissions, this type of request is still handled manually. The Library Manager index maintainer occasionally comes through to clear all the outstanding requests. They will merge this pull request when it is done. You will get a notification from GitHub at that time.
