The Software Collections images on registry.centos.org were originally available under the namespace 'sclo'.

For example : sclo/postgresql-96-centos7 is deprecated in favour of centos/postgresql-95-centos7

Please make sure you update any usages of said images to reflect the new name, as the old image names will be dropped from registry.centos.org soon. I will send out another email, a couple of days before the said images are dropped
