On August 10, 2023, HashiCorp announced that it was switching Terraform from the MPL v2 license to a “Business Source License” (BSL). This change only applies to new versions of Terraform going forward. Gruntwork customers can continue to use Gruntwork commercial and open source products as long as they do not upgrade beyond Terraform v1.5.5. Gruntwork is finalizing their plan for how customers can use all Gruntwork products with future Terraform versions in a way that will comply with all applicable licenses.
