terraform/CHANGELOG.md

1.14.0 (Unreleased)

NEW FEATURES:

• List Resources: List resources can be defined in *.tfquery.hcl files and allow querying and filterting existing infrastructure.

• A new Terraform command terraform query: Executes list operations against existing infrastructure and displays the results. The command can optionally generate configuration for importing results into Terraform.

• A new GenerateResourceConfiguration RPC allows providers to create more precise configuration values during import. (#37515)

• New top-level Actions block: Actions are provider defined and meant to codify use cases outside the normal CRUD model in your Terraform configuration. Providers can define Actions like aws_lambda_invoke or aws_cloudfront_create_invalidation that do something imparative outside of Terraforms normal CRUD model. You can configure such a side-effect with an action block and have actions triggered through the lifecycle of a resource or through passing the -invoke CLI flag. (#37553)

ENHANCEMENTS:

• terraform test: expected diagnostics will be included in test output when running in verbose mode" (#37362)

• terraform test: ignore prevent_destroy attribute during when cleaning up tests" (#37364)

• terraform stacks command support for -help flag (#37645)

BUG FIXES:

• Retrieve all workspace variables while doing a terraform import, include variables inherited from variable sets but not overwritten by the workspace. (#37241)

• Fix OSS backend proxy support by adding a proxy layer for OSS backend operations. Resolves hashicorp/terraform#36897. (#36897)

• console and test: return explicit diagnostics when referencing resources that were not included in the most recent operation. (#37663)

UPGRADE NOTES:

• The parallelism of Terraform operations within container runtimes may be reduced depending on the CPU bandwidth limit setting. (#37436)

• Building Terraform 1.14 requires macOS Monterey or later (due to being built on Go 1.25 which imposes these requirements) (#37436)

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.
