WCF Relay changes in new portal

Hi,

Here I'm referring the url https://azure.microsoft.com/en-us/blog/service-bus-and-the-new-azure-portal/.

Does breaking relay services out into their own namespaces have been changed the old architecture of the service bus or is it still same as the https://docs.microsoft.com/en-us/azure/service-bus-messaging/service-bus-architecture.

Cheers,

Madura
