 ## [Unreleased]
 
+### Added
+
+- BREAKING: Add required CLI argument and env var to set the image repository used to construct final product image names: `IMAGE_REPOSITORY` (`--image-repository`), eg. `oci.example.org/my/namespace` ([#778]).
+
 ### Changed
 
 - Document Helm deployed RBAC permissions and remove unnecessary permissions ([#770]).
 - BREAKING: `configOverrides` now only accepts the known config files (`hdfs-site.xml`,
   `core-site.xml`, `hadoop-policy.xml`, `ssl-server.xml`, `ssl-client.xml` and
   `security.properties`).
   Previously, arbitrary file names were silently accepted and ignored ([#777]).
-- Bump `stackable-operator` to 0.110.1 ([#777]).
