## 1.7.0 (Unreleased)

UPGRADE NOTES:

* Input validations are being restored to the state file in this version of Terraform. Due to a state interoperability issue ([#33770](https://github.com/hashicorp/terraform/issues/33770)) in earlier versions, users that require interaction between different minor series should ensure they have upgraded to the following patches:
    * Users of Terraform prior to 1.3.0 are unaffected;
    * Terraform 1.3 series users should upgrade to 1.3.10;
    * Terraform 1.4 series users should upgrade to 1.4.7;
    * Terraform 1.5 series users should upgrade to 1.5.7;
    * Users of Terraform 1.6.0 and later are unaffected.
 
  This is important for users with `terraform_remote_state` data sources reading remote state across different versions of Terraform.
* `nonsensitive` function no longer errors when applied to values that are already not sensitive. ([#33856](https://github.com/hashicorp/terraform/issues/33856))

NEW FEATURES:

* `terraform test`: Providers, modules, resources, and data sources can now be mocked during executions of `terraform test`. The following new blocks have been introduced within `.tftest.hcl` files:

    * `mock_provider`: Can replace provider instances with mocked providers, allowing tests to execute in `command = apply` mode without requiring a configured cloud provider account and credentials. Terraform will create fake resources for mocked providers and maintain them in state for the lifecycle of the given test file.
    * `override_resource`: Specific resources can be overridden so Terraform will create a fake resource with custom values instead of creating infrastructure for the overridden resource.
    * `override_data`: Specific data sources can be overridden so data can be imported into tests without requiring real infrastructure to be created externally first.
    * `override_module`: Specific modules can be overridden in their entirety to give greater control over the returned outputs without requiring in-depth knowledge of the module itself.

BUG FIXES:

* Ignore potential remote terraform version mismatch when running force-unlock ([#28853](https://github.com/hashicorp/terraform/issues/28853))
* Exit Dockerfile build script early on `cd` failure. ([#34128](https://github.com/hashicorp/terraform/issues/34128))

ENHANCEMENTS:

* `terraform test`: Providers defined within test files can now reference variables from their configuration that are defined within the test file. ([#34069](https://github.com/hashicorp/terraform/issues/34069))
* `terraform test`: Providers defined within test files can now reference outputs from run blocks. ([#34118](https://github.com/hashicorp/terraform/issues/34118))
* `terraform test`: Terraform functions are now available within variables and provider blocks within test files. ([#34204](https://github.com/hashicorp/terraform/issues/34204))
* `import`: `for_each` can now be used to expand the `import` block to handle multiple resource instances ([#33932](https://github.com/hashicorp/terraform/issues/33932))
