 ### Added
 
 - Add value `.sourceNamespace` to watch a namespace which is different from the one that external-dns is installed into when `.namespaced` is true. ([#6297](https://github.com/kubernetes-sigs/external-dns/pull/6297)) _@jplitza_
 - Add option to enable Gateway API ListenerSet support. ([#6381](https://github.com/kubernetes-sigs/external-dns/pull/6381)) _@speer_
 
+### Changed
+
+- Update _ExternalDNS_ OCI image version to [v0.21.0](https://github.com/kubernetes-sigs/external-dns/releases/tag/v0.21.0). ([#6354](https://github.com/kubernetes-sigs/external-dns/pull/6354)) _@vflaux_
+
 ### Fixed
 
 - Avoid creating cluster-scoped RBAC for Gateway API sources when running namespaced with `gatewayNamespace` set. Namespace listing permissions are now only added when `gatewayNamespace` is unset. ([#5843](https://github.com/kubernetes-sigs/external-dns/pull/5843)) _@TobyTheHutt_
