Summary

Terraform 1.13.0-beta1 introduces the 'terraform stacks' command and significant enhancements to 'terraform test', including in-file variable definitions and parallel teardowns. It also hardens filesystem function checks and workspace validation while promoting the RPC API to general availability.

⚠️ Breaking Changes

  • Filesystem functions now enforce consistency checks during apply; invalid data that previously passed may now cause errors.
  • Workspaces named with an empty string ("") are now rejected during validation and deletion.

Migration Steps

  1. For 'terraform test', add 'variable' definition blocks within test files for any referenced external variables to avoid potential diagnostic errors.

✨ New Features

  • Introduced 'terraform stacks' command to expose stack operations via the CLI.
  • The 'terraform rpcapi' command is now generally available for RPC-based operations.
  • Added support for defining external variables directly within 'terraform test' files.
  • Enhanced 'terraform test' file-level variable blocks to reference run outputs and other variables.
  • Added parallel execution support for teardown operations in 'terraform test'.

🐛 Bug Fixes

  • Fixed an issue where nested module outputs could lose sensitivity markers.
  • Added missing warning for ignored 'cloud' blocks in child modules.
  • Fixed a deadlock occurring in 'terraform test' when parallelism was set to 1.
  • Improved type checking error messages and static validation for object index references.
  • Fixed plan output to truncate invalid or dynamic references in relevant attributes.
  • Optimized performance by skipping redundant comparisons in planned set changes and high cardinality resource evaluation.
