## Added

- Support for the _RESTART_ deployment mode: restart the application on target instances using the last successful deployment's revision already on the instance, without downloading it again. See [deploymentMode](https://docs.aws.amazon.com/codedeploy/latest/APIReference/API_CreateDeployment.html#CodeDeploy-CreateDeployment-request-deploymentMode) in the AWS CodeDeploy API Reference.

## Fixed

- AppSpec file paths that resolve outside the application revision directory are now rejected.
