Core Concepts

Terraform 0.13 was released on August 10th, 2020. Some of the major new features in 0.13 include:

  1. The ability to use count, for_each, and depends_on with modules.

  2. A new required_providers block that makes it much easier to work with third-party providers.

  3. Custom variable validation.

0.13 is a major new release for Terraform, which means it includes a number of backwards incompatible changes. We have gone through all the Terraform modules in the Gruntwork Infrastructure as Code Library and updated them to work with Terraform 0.13. In order to use 0.13, you will need to update to these new versions and make other changes to your code, as described in the following section.
