Summary

This alpha release introduces Windows ARM64 builds, support for marking variables/outputs as deprecated, and the new `convert` function. It also includes numerous bug fixes across CLI, backend operations, and testing infrastructure.

⚠️ Breaking Changes

  • The `AWS_USE_FIPS_ENDPOINT` and `AWS_USE_DUALSTACK_ENDPOINT` environment variables now only respect explicit `true` or `false` values for the S3 backend, replacing the previous behavior where any non-empty value was treated as `true`.Fix: Ensure these environment variables are set explicitly to "true" or "false" if FIPS or DualStack endpoints are required.

✨ New Features

  • Added builds for Windows ARM64.
  • Introduced the ability to set a `deprecated` attribute on variable and output blocks to generate warnings upon use.
  • S3 backend now supports authentication via `aws login`.
  • The `validate` command now checks the `backend` block for type existence, required attributes, and backend-specific validation.
  • Introduced the `convert` function for precise inline type conversions.
  • Terraform now supports using variables and locals within module `source` and `version` attributes.

🐛 Bug Fixes

  • File-level error diagnostics are now included in JUnit XML skipped test elements during testing.
  • Fixed an issue where a refresh-only plan could result in a non-zero exit code when no changes were present.
  • Fixed crash in `terraform show -json` when the plan contained ephemeral resources with preconditions or postconditions.
  • Fixed `terraform init -json` to correctly format all backend configuration messages as JSON instead of plain text.
  • The `state show` command will now explicitly fail (return code 1) if it cannot render the named resource's state.
  • Terraform now raises an explicit error if a plan file intended for one workspace is applied against a different workspace.
  • The `replace_triggered_by` lifecycle argument now correctly reports an error if given an invalid attribute reference that does not exist on the target resource.
  • Fixed a nil pointer dereference crash during `terraform init` when the destination backend returns an error.
  • Progress events are now sent if the plan fails, improving UI integration.
  • Component instances now correctly report no-op plan/apply status, resolving UI inconsistencies with convergence destroy plans.
  • HTTP backend now returns conflicting lock information instead of the lock that failed to be taken.
  • Fixed a bug preventing Terraform from identifying when two states had different output values, which could affect backend migrations.
