Multiple API versions ?

[ctradu]

Is there a way to support multiple versions of an API ?
For example, I have in v0 group of handlers (firstHandler, secondHandler, thirdHandler)
And in v1 group of handlers I have an updated group: (secondHandler, thirdHandler, fourthHandler)
For v0 I want to show only first, second and third.
For v1 I want to show only second, third and fourth.
Also, given the grouping is done by the tags,
I would have in both v0 and v1 swagger docs groups from both generations of the API.
