1.7.0-beta2 (December 13, 2023)

UPGRADE NOTES:

• Input validations are being restored to the state file in this version of Terraform. Due to a state interoperability issue (#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 raises an error when applied to a value that is already non-sensitive. (#33856)

• terraform graph now produces a simplified graph describing only relationships between resources by default, for consistency with the granularity of information returned by other commands that emphasize resources as the main interesting object type and de-emphasize the other "glue" objects that connect them.

  The type of graph that earlier versions of Terraform produced by default is still available with explicit use of the -type=plan option, producing an approximation of the real dependency graph Terraform Core would use to construct a plan.

• terraform test: Simplify the ordering of destroy operations during test cleanup to simple reverse run block order. (#34293)

• backend/s3: The use_legacy_workflow argument now defaults to false. The backend will now search for credentials in the same order as the default provider chain in the AWS SDKs and AWS CLI. To revert to the legacy credential provider chain ordering, set this value to true. This argument, and the ability to use the legacy workflow, is deprecated. To encourage consistency with the AWS SDKs, this argument will be removed in a future minor version.

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.

• removed block for refactoring modules: Module authors can now record in source code when a resource or module call has been removed from configuration, and can inform Terraform whether the corresponding object should be deleted or simply removed from state.

  This effectively provides a configuration-driven workflow to replace terraform state rm. Removing an object from state is a new type of action which is planned and applied like any other. The terraform state rm command will remain available for scenarios in which directly modifying the state file is appropriate.

BUG FIXES:

• Ignore potential remote terraform version mismatch when running force-unlock (#28853)
• Exit Dockerfile build script early on cd failure. (#34128)
• terraform test: Stop attempting to destroy run blocks that have no actual infrastructure to destroy. This fixes an issue where attempts to destroy "verification" run blocks that load only data sources would fail if the underlying infrastructure referenced by the run blocks had already been destroyed. (#34331)

ENHANCEMENTS:

• terraform test: Providers defined within test files can now reference variables from their configuration that are defined within the test file. (#34069)
• terraform test: Providers defined within test files can now reference outputs from run blocks. (#34118)
• terraform test: Terraform functions are now available within variables and provider blocks within test files. (#34204)
• terraform test: Terraform will now load variables from any terraform.tfvars within the testing directory, and apply the variable values to tests within the same directory. (#34341)
• terraform graph: Now produces a simplified resources-only graph by default. (#34288)
• terraform console: Now supports a -plan option which allows evaluating expressions against the planned new state, rather than against the prior state. This provides a more complete set of values for use in console expressions, at the expense of a slower startup time due first calculating the plan. (#34342)
• import: for_each can now be used to expand the import block to handle multiple resource instances (#33932)
• If the proposed change for a resource instance is rejected either due to a postcondition block or a prevent_destroy setting, Terraform will now include that proposed change in the plan output alongside the relevant error, whereas before the error would replace the proposed change in the output. (#34312)
• .terraformignore: improve performance when ignoring large directories (#34400)
