The first stable release of OpenTofu (the fork of Terraform) has now been released. This release is lagging behind the current 1.6.6 release of Terraform, but it is a big first step. This release is backwards compatible with Terraform 1.6.0 and includes a few new features.

The big new features:

• Module testing feature
• Enhanced S3 state backend
• Replacement default registry (registry.opentofu.org) to replace registry.terraform.io.
