API Versions

We would like to support multiple versions of our API.  That is, when
an update for our API is released continue to support For example, a
method foo.get might require an extra argument in a newer version.

What would you recommend to specify a version in the request?

1) Use a version in the endpoint URL?  Say our current endpoint is:

    http://localhost/rpc

    So modify the endpoint for the version?  Something like one
    of these:

    http://localhost/rpc/1.23
    http://localhost/rpc?version=1.23
    http://localhost/rpc-1.23

2) Add an argument (or named parameter in a stuct) in the payload:

    version => 1.23


3) Modify the method name?

    foo.get

    foo.get.1.23

Thanks,
