Publishing several versions of the same stub
During testing, you might discover that you require several versions of a stub and you might not want to override the previous version.
When you are deploying a stub, increment the stub version on the Publish
Stubs window. New versions are denoted by the blue arrow under Stubs to be
published.![Publish stubs](../images/publish_stubs.jpg)

Ensure that the endpoints of the new stub version do not clash with the current stub version that is running. For example, both might be referencing the same queues or HTTP URLs.
