+### Fixes

+- Add `status.clusterType` in `KonnectGatewayControlPlane` to save the
+  clusterType of the Konnect control plane after the `KonnectGatewayControlPlane`
+  is attached to a Konnect control plane. This is used to fix the wrong
+  cluster type fetched in `KonnectExtension` for mirrored control planes.
