How do I use API versioning?
Quote from services.versions.api.php


  For clients that want to request a specific version they need to pass a certain header
  
  
  services_RESOURCE_METHOD_version = version
  as an example, services_system_set_variable_version = 1.2
  @see ServicesVersionTests for code examples
