<p><a href="https://docs.aws.amazon.com/cloudformation/">AWS CloudFormation</a>&nbsp;now makes it simpler to complete an update rollback and get back to deploying. An update rollback returns your stack to a known good state. Starting today, if some resources cannot roll back automatically, force rollback enables you to complete the rollback in a single operation. It works across every CloudFormation workflow, from the <a href="https://docs.aws.amazon.com/cli/latest/reference/cloudformation/">AWS CLI</a>, and SDKs to <a href="https://docs.aws.amazon.com/cdk/v2/guide/">AWS CDK</a>&nbsp;and AI agents.</p> <p>With force rollback, CloudFormation completes the update rollback and returns your stack to a deployable state in a single operation, instead of requiring you to identify, list, and retry the operation for each affected resource. Any resource that still needs attention, such as one affected by a change outside CloudFormation, is recorded for you to review and resolve it before your next deployment.</p> <p>To get started, run continue update rollback with the force rollback option, then create a <a href="https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/drift-aware-change-sets.html">drift-aware change set</a> to review any configuration differences before your next deployment. To learn more, see &nbsp;<a href="https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-continueupdaterollback.html">Continue rolling back an update&nbsp;</a> in the AWS CloudFormation User Guide.</p> <p>Force rollback is available in all Regions at no additional cost. Refer to the &nbsp;<a href="https://docs.aws.amazon.com/general/latest/gr/cfn.html#cfn_region">AWS Region table&nbsp;</a> for service availability details.</p>
