## Changed Features
-* When a Signature Scan is skipped due to the minimum scan interval on Black Duck not being met, [solution_name] by default will treat the run as a success and will not wait for those skipped scans. If the property detect.force.success.on.skip is set to false, [solution_name] will instead return exit code 13 when a scan is skipped.
