+## 1.13.0 (August 20, 2025)
+
+
+NEW FEATURES:
+
+* The new command `terraform stacks` exposes some stack operations through the cli. The available subcommands depend on the stacks plugin implementation. Use `terraform stacks -help` to see available commands. ([#36931](https://github.com/hashicorp/terraform/issues/36931))
+
+
+ENHANCEMENTS:
+
+* Filesystem functions are now checked for consistent results to catch invalid data during apply ([#37001](https://github.com/hashicorp/terraform/issues/37001))
+
+* Allow successful init when provider constraint matches at least one valid version ([#37137](https://github.com/hashicorp/terraform/issues/37137))
+
+* Performance fix for evaluating high cardinality resources ([#37154](https://github.com/hashicorp/terraform/issues/37154))
+
+*  TF Test: Allow parallel execution of teardown operations ([#37169](https://github.com/hashicorp/terraform/issues/37169))
+
+* `terraform test`: Test authors can now specify definitions for external variables that are referenced within test files directly within the test file itself. ([#37195](https://github.com/hashicorp/terraform/issues/37195))
+
+* `terraform test`: File-level variable blocks can now reference run outputs and other variables." ([#37205](https://github.com/hashicorp/terraform/issues/37205))
+
+* skip redundant comparisons when comparing planned set changes ([#37280](https://github.com/hashicorp/terraform/issues/37280))
+
+* type checking: improve error message on type mismatches. ([#37298](https://github.com/hashicorp/terraform/issues/37298))
+
+
+BUG FIXES:
+
+* Added a missing warning diagnostic that alerts users when child module contains an ignored `cloud` block. ([#37180](https://github.com/hashicorp/terraform/issues/37180))
+
+* Nested module outputs could lose sensitivity, even when marked as such in the configuration ([#37212](https://github.com/hashicorp/terraform/issues/37212))
+
+* workspace: Updated validation to reject workspaces named "" ([#37267](https://github.com/hashicorp/terraform/issues/37267))
+
+* workspace: Updated the `workspace delete` command to reject `""` as an invalid workspace name ([#37275](https://github.com/hashicorp/terraform/issues/37275))
+
+* plan: truncate invalid or dynamic references in the relevant attributes ([#37290](https://github.com/hashicorp/terraform/issues/37290))
+
+* Test run Parallelism of 1 should not result in deadlock ([#37292](https://github.com/hashicorp/terraform/issues/37292))
+
+* static validation: detect invalid static references via indexes on objects. ([#37298](https://github.com/hashicorp/terraform/issues/37298))
+
+* Fixes resource identity being dropped from state in certain cases ([#37396](https://github.com/hashicorp/terraform/issues/37396))
+
+
+NOTES:
+
+* The command `terraform rpcapi` is now generally available. It is not intended for public consumption, but exposes certain Terraform operations through an RPC interface compatible with [go-plugin](https://github.com/hashicorp/go-plugin). ([#37067](https://github.com/hashicorp/terraform/issues/37067))
+
+
+UPGRADE NOTES:
+
+* `terraform test`: External variables referenced within test files should now be accompanied by a `variable` definition block within the test file. This is optional, but users with complex external variables may see error diagnostics without the additional variable definition. ([#37195](https://github.com/hashicorp/terraform/issues/37195))

@@ -3,10 +3,6 @@ EXPERIMENTS:
 Experiments are only enabled in alpha releases of Terraform CLI. The following features are not yet available in stable releases.
 
 - The experimental "deferred actions" feature, enabled by passing the `-allow-deferral` option to `terraform plan`, permits `count` and `for_each` arguments in `module`, `resource`, and `data` blocks to have unknown values and allows providers to react more flexibly to unknown values.
-- `terraform test cleanup`: The experimental `test cleanup` command. In experimental builds of Terraform, a manifest file and state files for each failed cleanup operation during test operations are saved within the `.terraform` local directory. The `test cleanup` command will attempt to clean up the local state files left behind automatically, without requiring manual intervention.
-- `terraform test`: `backend` blocks and `skip_cleanup` attributes:
-  - Test authors can now specify `backend` blocks within `run` blocks in Terraform Test files. Run blocks with `backend` blocks will load state from the specified backend instead of starting from empty state on every execution. This allows test authors to keep long-running test infrastructure alive between test operations, saving time during regular test operations.
-  - Test authors can now specify `skip_cleanup` attributes within test files and within run blocks. The `skip_cleanup` attribute tells `terraform test` not to clean up state files produced by run blocks with this attribute set to true. The state files for affected run blocks will be written to disk within the `.terraform` directory, where they can then be cleaned up manually using the also experimental `terraform test cleanup` command.
