1.13.0-alpha20250623 (June 23, 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)

ENHANCEMENTS:

Filesystem functions are now checked for consistent results to catch invalid data during apply (#37001)
Allow successful init when provider constraint matches at least one valid version (#37137)
Performance fix for evaluating high cardinality resources (#26355)
TF Test: Allow parallel execution of teardown operations (#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)
terraform test: File-level variable blocks can now reference run outputs and other variables." (#37205)

BUG FIXES:

Added a missing warning diagnostic that alerts users when child module contains an ignored cloud block. (#37180)
Nested module outputs could lose sensitivity, even when marked as such in the configuration (#37212)

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. (#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)

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.
