+# Consul on Kubernetes 1.5.0
+
+We are pleased to announce the following Consul updates.
+
+## Release highlights
+
+- **External Services CRD**: You can now configure and register external services, including their health checks, alongside existing Kubernetes application manifests with the new [`Registration` Custom Resource Definition (CRD)](/consul/docs/connect/config-entries/registration). The CRD removes the requirement to deploy a terminating gateway in order to register a service running on an external node in Consul on Kubernetes. Refer to [Register external services on Kubernetes overview](/consul/docs/k8s/deployment-configurations/external-service) for more information.
+
+- **File system certificate**: A new [`file-system-certificate` configuration entry](/consul/docs/connect/config-entries/file-system-certificate) for Consul API Gateway on VMs supports specifying a filepath to the certificate and private key on the local system. Consul on Kubernetes deployments that use `consul-k8s` Helm chart v1.5.0 or later use file system certificates instead of inline certificates without additional configuration. For information about certificate configuration for Kubernetes environments, refer to [Gateway Resource Configuration](/consul/docs/connect/gateways/api-gateway/configuration/gateway).
+
+- **v2 catalog API deprecation**: Consul introduced an experimental v2 Catalog API in v1.17.0. This API supported multi-port Service configurations on Kubernetes, and it was made available for testing and development purposes. The v2 catalog and its support for multiport Kubernetes Services were deprecated in the v1.19.0 release.
+
+## Supported software
+
+This version of Consul on Kubernetes supports the following software versions:
+
+- Consul v1.19.x
+- Consul Dataplane v1.5.x. Refer to [Envoy and Consul Dataplane](/consul/docs/v1.19.x/connect/proxies/envoy#envoy-and-consul-dataplane) for details about Consul Dataplane versions and the available packaged Envoy version.
+- Kubernetes 1.27.x - 1.30.x
+- kubectl 1.27.x - 1.30.x
+- Helm 3.11.3+
+
+Refer to [Supported Consul and Kubernetes versions](/consul/docs/v1.19.x/k8s/compatibility#supported-consul-and-kubernetes-versions) for more information.
+

 - **Transparent Proxy on Nomad**: Consul’s CNI plugin enables the use of transparent proxy for seamlessly redirecting traffic through the Envoy proxy without requiring application changes, or elevated network privileges for the workload. As a result, you can onboard applications without additional configuration between a service and its upstreams.
