You can now tag launch templates at the time they are created, eliminating the need to run custom tagging scripts after creation. In addition, you can now set resource-level permissions on the CreateLaunchTemplate API, allowing you to implement stronger security policies by giving more granular control over who has access to that API. Resource-level permissions and tagging your launch templates on creation simplifies management and ensures that your launch templates are secured upon creation.
