+- Set the OverlappingTLSConfig condition on Listeners with overlapping TLS hostnames. [3709](https://github.com/nginx/nginx-gateway-fabric/pull/3709)
+
+BUG FIXES:
+
+- Fix an issue where the NGINX Pod couldn't connect to control plane if multiple Pods shared the NGINX Pod's IP address. [3673](https://github.com/nginx/nginx-gateway-fabric/pull/3673)
+
+DOCUMENTATION:
+
+- Add simplified architecture diagrams for traffic flow and config changes. [3557](https://github.com/nginx/nginx-gateway-fabric/pull/3557)
+
+HELM CHART:
+
+- The version of the Helm chart is now 2.1.0.
+- Allow users to specify nginxGateway.name to configure names of deployments. [3528](https://github.com/nginx/nginx-gateway-fabric/pull/3528)

+
+UPGRADE:
+
+- **Important:** Upgrading from v2.0.x to 2.1 requires the NGINX Gateway Fabric control plane to be uninstalled and then reinstalled to avoid any downtime to user traffic. CRDs do not need to be removed. The NGINX data plane deployment is not affected by this process, and traffic should still flow uninterrupted. For more information on how to do so, view our guide on [Upgrading NGINX Gateway Fabric](https://docs.nginx.com/nginx-gateway-fabric/install/upgrade-version/)
+
+COMPATIBILITY:
+
+- Gateway API version: `1.3.0`
+- NGINX version: `1.29.0`
+- NGINX Plus version: `R35`
+- NGINX Agent version: `v3.2.0`
+- Kubernetes version: `1.25+`
+
+CONTAINER IMAGES:
+
+- Control plane: `ghcr.io/nginx/nginx-gateway-fabric:2.1.0`
