Helm Upgraded the Operator, Not Its CRD

The backup operator archiver in identity was just upgraded with Helm from chart 1.0.0 to 1.1.0 (both are in ~/charts). Version 1.1.0 adds a priority field to its BackupPlan custom resource. But the team can't apply ~/nightly-plan.yaml: kubectl rejects it with strict decoding error: unknown field "spec.priority".
