+Azure Automation introduces [Runtime environment](runtime-environment-overview.md) (preview) that provides a simple and hassle-free experience for [updating scripts](quickstart-update-runbook-in-runtime-environment.md) to the latest language versions. It also provides complete control to configure the script execution environment, without worrying about conflicting module versions in a single Automation account. All existing runbooks are automatically available in the new Runtime environment experience with zero manual effort. You can navigate seamlessly between the old and new experience with a single click. [Learn more](manage-runtime-environment.md).
