The Cloud Authentication API uses a URI versioning
scheme. The first element of the path contains the target
version identifier: for example, in
https://identity.api.rackspacecloud.com/v1.1//v1.1/…, the
API version is 1.1. Other than requests to query for
version, all requests must contain a target version. Any
features or functionality changes that would necessitate a
break in API compatibility will require a new version,
which will result in the URI version being updated
accordingly. When new API versions are released, older
versions will be marked as DEPRECATED.
Rackspace will work with developers and partners to ensure
that there is adequate time to migrate to the new version
before deprecated versions are discontinued.
