+## 1.2.0
+
+**Release date:** 2023-12-05
+
+This minor release comes with API changes, bug fixes and several new features.
+
+### Bucket
+
+A new field, `.spec.prefix`, has been added to the Bucket API, which enables
+server-side filtering of files if the object's `.spec.provider` is set to
+`generic`/`aws`/`gcp`.
+
+### OCIRepository and HelmChart
+
+Two new fields, `.spec.verify.matchOIDCIdentity.issuer` and
+`.spec.verify.matchOIDCIdentity.subject` have been added to the HelmChart and
+OCIRepository APIs. If the image has been keylessly signed via Cosign, these
+fields can be used to verify the OIDC issuer of the Fulcio certificate and the
+OIDC identity's subject respectively.
+
+### HelmRepository
+
+A new boolean field, `.spec.insecure`, has been introduced to the HelmRepository
+API, which allows connecting to a non-TLS HTTP container registry. It is only
+considered if the object's `.spec.type` is set to `oci`.
+
+From this release onwards, HelmRepository objects of type OCI are treated as
+static objects, i.e. they have an empty status.
+Existing objects undergo a one-time automatic migration and new objects
+will be undergo a one-time reconciliation to remove any status fields.
+
+Additionally, the controller now performs a shallow clone if the
+`.spec.ref.name` of the GitRepository object points to a branch or a tag.
+
+Furthermore, a bug has been fixed, where the controller would try to
+authenticate against public OCI registries if the HelmRepository object has a
+reference to a Secret containing a CA certificate.
+
+Lastly, dependencies have been updated to their latest version, including an
+update of Kubernetes to v1.28.4.
