AFAICS, this is done: https://koji.fedoraproject.org/koji/buildinfo?buildID=2267076 . That build is from July and is tagged stable for f39 and Rawhide. the releng ticket is still open, but it's unclear if releng actually has to do anything here. Marking ON_QA.
F39 was released on November 7th, so I am closing this tracker. If this Change was not completed, please notify me ASAP.
