Henrik, No, not the only approach. It really depends on what changes you're making.
Most changes that I've come across have been small changes/extensions to existing services--adding new operations or adding additional data to a message payload. These types of changes are forward compatible with caveats e.g. new elements are optional and not required. This change wouldn't necessarily require a new endpoint. If you make massive changes you essentially have created a new service...

Defining it at a new endpoint? I mean that's what I do for know, because I can't think of any other way...but..you know.. :-) Maybe this would be a task for the UDDI registry? I dunno.? Do you? Anyone?
