The version is in the format `<version>+<digest[0:12]>`. The digest of the OCI artifact
|

is appended to the version to ensure that a change in the artifact content triggers

a new release. The controller will automatically perform a Helm upgrade when the

OCIRepository detects a new digest in the OCI artifact stored in registry, even if
|

the version inside `Chart.yaml` is unchanged.
|
||||
|
||||
**Warning:** One of `.spec.chart` or `.spec.chartRef` must be set, but not both.
|
||||
If switching from `.spec.chart` to `.spec.chartRef`, the HelmRelease will uninstall
|
||||
the previous release before installing the new one.
|
||||
When switching from `.spec.chart` to `.spec.chartRef`, the controller will perform
|
||||
an Helm upgrade and will garbage collect the old HelmChart object.

|
||||
**Note:** On multi-tenant clusters, platform admins can disable cross-namespace
|
||||
references with the `--no-cross-namespace-refs=true` flag. When this flag is
|
||||
set, the HelmRelease can only refer to Sources in the same namespace as the
|
||||
references with the `--no-cross-namespace-refs=true` controller flag. When this flag is
|
||||
set, the HelmRelease can only refer to OCIRepositories in the same namespace as the
|
||||
HelmRelease object.
