Terraform 0.13 introduces powerful new meta-arguments for modular workflows, including count, for_each, and depends_on, which can simplify and streamline Terraform configurations at the resource-level. These features allow modules to produce multiple instances systematically, enabling a concise way to declare shared dependencies between module objects in the calling module. The new features are designed to make configuration easier to maintain and allow Terraform to maximize concurrency when making many changes in a single operation. The `depends_on` meta-argument is available for module-centric workflows and can be used to imply dependencies using data flow, but its use is recommended as a last resort.
