+    As of 14.6 bundler-audit is being deprecated from Dependency Scanning. It will continue to be in our CI/CD template while deprecated. We are removing bundler-audit from Dependency Scanning on May 22, 2022 in 15.0. After this removal Ruby scanning functionality will not be affected as it is still being covered by Gemnasium. 
+
+    If you have explicitly excluded bundler-audit using DS_EXCLUDED_ANALYZERS you will need to clean up (remove the reference) in 15.0. If you have customized your pipeline's Dependency Scanning configuration, for example to edit the `bundler-audit-dependency_scanning` job, you will want to switch to gemnasium-dependency_scanning before removal in 15.0, to prevent your pipeline from failing. If you have not used the DS_EXCLUDED_ANALYZERS to reference bundler-audit, or customized your template specifically for bundler-audit, you will not need to take action.
