+## New features
+-
+
+## Bug fixes
+- Fixed local object reference resolution from parent policy in merged BackendTrafficPolicies.
+- Fixed route and policy status aggregation across multiple GatewayClasses managed by the same controller, so resources preserve status from all relevant parents and ancestors instead of being overwritten by the last processed GatewayClass.
+- Exclude unmanaged route parents from xPolicy status ancestors.
+- Fixed an issue where computeHosts doesn't work when listener and route both wildcard.
+- Add ownership references to ratelimit ConfigMap and HPA resources.
+- Made ConnectionLimit.Value optional so users can configure MaxConnectionDuration, MaxRequestsPerConnection, or MaxStreamDuration without setting a max connections value.
