+## Release 0.2.0

+*October 25, 2022*
+
+This release extends the support of the features of the Gateway API resources.

+FEATURES:
+* Support the Pod IPs instead of the virtual IP of a Service in the NGINX upstream. Additionally, NGINX Kubernetes Gateway will pick up any changes to the Pod IPs and update the NGINX upstream accordingly. [PR-221](https://github.com/nginxinc/nginx-kubernetes-gateway/pull/221)
+* Support the redirect filter in an HTTPRoute rule. [PR-218](https://github.com/nginxinc/nginx-kubernetes-gateway/pull/218)
+* Support weights in backendRefs in the HTTPRoute (traffic splitting). [PR-261](https://github.com/nginxinc/nginx-kubernetes-gateway/pull/261)
+* Support the ObservedGeneration field in the HTTPRoute status. [PR-254](https://github.com/nginxinc/nginx-kubernetes-gateway/pull/254)
+
+BUG FIXES:
+* Do not require the namespace in the `--gateway-ctlr-name` cli argument. [PR-235](https://github.com/nginxinc/nginx-kubernetes-gateway/pull/235)
+* Ensure NGINX Kubernetes Gateway exits gracefully during shutdown. [PR-250](https://github.com/nginxinc/nginx-kubernetes-gateway/pull/250)
+* Handle query param names in case-sensitive way. [PR-220](https://github.com/nginxinc/nginx-kubernetes-gateway/pull/220)
+
+DEPENDENCIES:
+* Use the latest NGINX 1.23 image. [PR-275](https://github.com/nginxinc/nginx-kubernetes-gateway/pull/275)
+* Bump sigs.k8s.io/gateway-api from 0.5.0 to 0.5.1 [PR-251](https://github.com/nginxinc/nginx-kubernetes-gateway/pull/251)
