TCPRoute and UDPRoute have graduated from Experimental to Standard (v1 API), enabling portable layer 4 routing for workloads like databases, DNS, VoIP, and gaming without relying on implementation-specific CRDs. The release also introduces a new experimental API group separation: new experimental resources now live under gateway.networking.x-k8s.io with an X prefix (e.g., XBackend, XMesh), making the experimental vs. stable boundary explicit at the API group level rather than relying on version strings. XBackend, a new experimental resource, adds support for ExternalHostname destinations useful for egress use cases such as routing to external AI APIs. ## Full article daily.dev links to this article rather than hosting it.
