+Support for Gateway API 1.5.1::
++
+With this release, {product-title} supports Gateway API version 1.5.1. The Gateway API controller is based on {SMProductName} 3.4 and Istio 1.30.
++
+This release adds support for the following Gateway API version 1.5.1 features:
++
+--
+* `TLSRoute` resources that route TLS traffic by matching the Server Name Indication (SNI) hostname, typically for passthrough scenarios where the backend, rather than the gateway, terminates TLS.
+* A Cross-Origin Resource Sharing (CORS) filter on `HTTPRoute` resources that configures CORS headers by using a built-in filter.
+* `ReferenceGrant` resources at the stable `gateway.networking.k8s.io/v1` API version.
+--
