Orchestration Endpoint

We are creating a new interface to a 3rd party application, and we are using Orchestration endpoints in that application. We generally use the endpoint in this structure: /jderest/v3/orchestrator/{orchestration} as we have converted all our Orchestrations to v3. However, as there is potential going forward to new versions of Orchestrations, we would ideally like to use this structure: /jderest/orchestrator/{orchestration} so we don't need to change anything on the 3rd party application (no reference to a version).

Using the structure /jderest/orchestrator/{orchestration} will this default to the version being used (ie v3 or in the future v4)? Or is there some configuration that I can tell it to use a specific version by default?
