 - Additional methods have been added to the SiftClient Rules resource to allow easy access to RuleVersions
 - Reports can now be generated from RuleVersions
 - The Jobs and Reports resources now have a `wait_until_complete` sync/async method, which provides a convenient way to wait until a job or report is complete, with configurable polling and timeout settings.
-- When creating reports, SiftClient now returns a Job object, to signify that the report is still in progress. Waiting on the job with `wait_until_complete` will return the completed report once finished. The report_id can also still be accessed directly from the job object if needed.
