+# Restate Operator v2.5.1 Release Notes
+
+## Highlights
+
+- **Fix: Knative deployments now work with Restate Cloud** — The Knative reconciler was passing raw in-cluster Route URLs to the Restate admin API, which Restate Cloud cannot reach. Service URLs are now routed through the cloud tunnel, matching the existing ReplicaSet behavior.
+
+## Bug Fixes
+
+### Knative service URLs not tunneled for Restate Cloud
+
+When using RestateDeployment in Knative mode with a Restate Cloud endpoint
+(`spec.restate.register.cloud`), the operator passed the in-cluster Knative
+Route URL directly to `register_service_with_restate`. Restate Cloud cannot
+reach in-cluster URLs, so registration failed and the operator looped
+indefinitely.
+
+The fix extracts a `maybe_tunnel_url()` method from `RestateAdminEndpoint` and
+calls it in the Knative reconciler after resolving the Route URL, matching how
+the ReplicaSet reconciler already handled this case.
+
+**Impact on Users:**
+- **Knative + Restate Cloud deployments**: This was broken; it now works.
+- **Knative + non-Cloud deployments**: No change; `maybe_tunnel_url` is a no-op
+  when `cloud` is not set.
+- **ReplicaSet deployments**: No change. The internal refactoring of
+  `service_url_for_deployment()` is equivalent to the previous behavior.
