Release Notes

gruntwork-io/terratest

### [`v0.40.0`](https://togithub.com/gruntwork-io/terratest/releases/v0.40.0) [Compare Source](https://togithub.com/gruntwork-io/terratest/compare/v0.39.0...v0.40.0) #### Modules affected #### Description **Terraform 1.1 upgrade**: We have verified that this repo is compatible with Terraform 1.1.x! - Note that no changes have been made to terratest core so it is possible Terratest continues to work with Terraform 0.12 and above. - However, from this release and onward, we will only be running tests with Terraform 1.1.x against this repo, so we recommend updating to 1.1.x soon! #### Related links - [https://github.com/gruntwork-io/terratest/pull/1052](https://togithub.com/gruntwork-io/terratest/pull/1052)
