* The `terraform graph` command no longer supports `-type=validate` and `-type=eval` options. The validate graph is always the same as the plan graph anyway, and the "eval" graph was just an implementation detail of the `terraform console` command. The default behavior of creating a plan graph should be a reasonable replacement for both of the removed graph modes. (Please note that `terraform graph` is not covered by the Terraform v1.0 compatibility promises, because its behavior inherently exposes Terraform Core implementation details, so we recommend it only for interactive debugging tasks and not for use in automation.)
* cli: The (currently-experimental) `terraform add` generates a starting point for a particular resource configuration. ([#28874](https://github.com/hashicorp/terraform/issues/28874))
* config: Terraform now checks the syntax of and normalizes module source addresses (the `source` argument in `module` blocks) during configuration decoding rather than only at module installation time. This is largely just an internal refactoring, but a visible benefit of this change is that the `terraform init` messages about module downloading will now show the canonical module package address Terraform is downloading from, after interpreting the special shorthands for common cases like GitHub URLs. ([#28854](https://github.com/hashicorp/terraform/issues/28854))
* core: Fixed an issue where provider configuration input variables were not properly merging with values in configuration ([#29000](https://github.com/hashicorp/terraform/issues/29000))
