 There are three special cases:
 - *Start*. When the Ingress Controller starts, it processes all resources in the cluster and only then reloads NGINX. This avoids creating a "reload storm" by reloading only once.
-- *Batch updates*. When the Ingress Controller receives a number of concurrent requests from the Kubernetes API, it will pause NGINX reloads untill the task queue is empty. This reduces the number of reloads to minimize the impact of batch updates and reduce the risk of OOM (Out of Memory) errors.

 - *NGINX Plus*. If the Ingress Controller uses NGINX Plus, it will not reload NGINX Plus for changes to the Endpoints resources. In this case, the Ingress Controller will use the NGINX Plus API to update the corresponding upstreams and skip reloading.

 OVERVIEW:
 
 * Added support for enabling [proxy_protocol](https://github.com/nginxinc/kubernetes-ingress/tree/v2.4.0/examples/shared-examples/proxy-protocol) when port 443 is being used for both HTTPS traffic and [TLS Passthrough traffic](https://github.com/nginxinc/kubernetes-ingress/tree/v2.4.0/examples/custom-resources/tls-passthrough).
-* Updates to the TransportServer resource to support using [ExternalName services] (https://kubernetes.io/docs/concepts/services-networking/service/#externalname). For examples, see [externalname-services](https://github.com/nginxinc/kubernetes-ingress/tree/v2.4.0/examples/custom-resources/externalname-services).

 * VirtualServer resource now supports [wildcard hostname](https://kubernetes.io/docs/concepts/services-networking/ingress/#hostname-wildcards).
-* NGINX Ingress Controller images including the combined NGINX AppProtect WAF and NGINX AppProtect DoS solutions are now published to our registry.

See [Images with NGINX Plus](https://docs.nginx.com/nginx-ingress-controller/technical-specifications/#images-with-nginx-plus) for a detailed list of images in our registry.
 * Added support for watching multiple namespaces using the [-watch-namespace](https://docs.nginx.com/nginx-ingress-controller/configuration/global-configuration/command-line-arguments/#-watch-namespace-string) cli argument. This can configured by passing a comma-separated list of namespaces to the `-watch-namespace` CLI argument (e.g. `-watch-namespace=ns-1,ns-2`).
 * A new cli argument has been added: [-include-year](https://docs.nginx.com/nginx-ingress-controller/configuration/global-configuration/command-line-arguments/#-include-year). This appends the current year to the log output from the ingress controller. Example output: `I20220512 09:20:42.345457`.
 * Post-startup configuration reloads have been optimized to reduce traffic impacts. When many resources are modified at the same time, changes are combined to reduce the number of data plane reloads.
