AWS CloudFormation has enhanced CreateStack and UpdateStack actions to support Macros. This means customers can now embed macros in templates with nested stacks. Macros enable powerful custom processing on CloudFormation templates, from simple actions like find-and-replace operations to extensive transformation of entire templates.
In the AWS SDKs and CLI, templates containing macros can now be executed directly using the CreateStack and UpdateStack actions. This functionality is available in all regions today. For more information, visit our API reference.
