Upgrading to 3.11 needs downtime but the changelog doesn't say so

pulp_deb 3.11.0 adds migrations 0041 and 0042, which make new columns NOT NULL. Any 3.10 code still running during the upgrade then fails to upload debs or publish apt repos.

This doesn't follow the zero-downtime upgrade requirements. I think just a changelog note saying this release needs downtime would be good enough.
