"max_version" is maximum version, "min_version" is minimum version.
While it is typical for there to be a single API for a given service, it is
also sometimes useful to be able to offer more than one version of a given API.
Common examples of this are when an older version is still made available in
order to support clients that have not yet upgraded to the current version, or
when a new API version is being tested before it is released. To distinguish
these different APIs for the same service, the `status` value is used. The
following values can be returned for status:
============ =======
Status Meaning
============ =======
CURRENT The newest API that is currently being developed and improved.
Unless you need to support old code, use this API.
SUPPORTED An older version of the API. No new features will be added to
this version, but any bugs discovered in the code may be fixed.
DEPRECATED This API will be removed in the foreseeable future. You should
start planning on using alternatives.
EXPERIMENTAL This API is under development ('alpha'), and you can expect it to
change or even be removed.
============ =======
When the requested version is out of range for the server, the server returns
status code **406 Not Acceptable** along with a response body.
