+{{< relnote >}}
+
+## Changes
+
+- **Fixed** a bug where overlapping wildcard hosts in a `VirtualService` produces incorrect routing configurations
+  when wildcard services were selected (e.g. in `ServiceEntry`).
+  ([Issue #45415](https://github.com/istio/istio/issues/45415))
+
+- **Fixed** an issue where `istioctl proxy-config ecds` didn't display all `EcdsConfigDump`.
+
+- **Fixed** an issue where new endpoints may not be sent to proxies.
+  ([Issue #48373](https://github.com/istio/istio/issues/48373))
+
+- **Fixed** an issue where installing with Stackdriver and using custom configurations would prevent Stackdriver from being
+  enabled.
+
+- **Fixed** an issue where long-lived connections, TCP bytes and gRPC, could result in a proxy memory leak.

+As [previously announced](/news/support/announcing-1.18-eol/), support for Istio 1.18 has now officially ended.
+
+At this point we will no longer back-port fixes for security issues and critical bugs to 1.18. We highly recommend that
+you upgrade to the latest version of Istio ({{<istio_release_name>}}) if you haven't already.
