Comment 9 Gregory Charot 2020-03-18 15:22:26 UTC 
Moving to 16.1.1, same target as the playbook RFEs.
Comment 13 Lon Hohberger 2020-07-29 10:47:10 UTC 
According to our records, this should be resolved by openstack-glance-19.0.3-0.20200421223423.3e16bc7.el8ost.  This build is available now.
Comment 15 Cyril Roelandt 2021-02-15 19:21:48 UTC 
Though not strictly required, I merged https://code.engineering.redhat.com/gerrit/#/c/227834/ . It disables all the functional/unit tests related to registry, and will make it easier to merge future backports.
