TL;DR

Terraform expands module flexibility and provider capabilities, most notably by allowing import blocks inside modules.

New

• Module Imports: Support for import blocks (bringing existing infrastructure into state) within modules.
• Enhanced Data Handling: New store block in terraform_data for ephemeral/sensitive values and support for nested blocks as computed values in providers.
• CLI Improvements: Added JSON output for workspace list and state show, Mermaid format support for terraform graph, and scoped evaluation in terraform console.
• Lifecycle Control: Resource action triggers now support on_failure modes (halt, taint, continue) and destroy=false in lifecycle blocks.

Fixes Worth Knowing

• Resolved a terraform apply panic occurring when plans contained no-op changes for deposed objects with lifecycle conditions.
• Fixed an issue where import blocks ignored provider local names.

TL;DR

Terraform now provides more accurate plan outputs and improved error handling, resolving issues with removed resources and variable errors.

Fixes Worth Knowing

• Plan outputs now correctly reflect removed resources (infrastructure definitions).
• Terraform commands (plan, query, refresh) now return correct error codes when variable issues occur.
• Module installation is more reliable, especially with null or sensitive sources (reusable code packages).
• The terraform console tool is more stable and avoids crashes with deprecated values (interactive environment).

TL;DR

Terraform now supports precondition and postcondition blocks (configuration checks) allowing module authors to define and enforce assumptions about infrastructure state, halting execution if they aren’t met.

Breaking

• Go-TFE SDK v1.0: Terraform Cloud integration now uses a major version upgrade of the underlying Go-TFE SDK, potentially impacting custom integrations using that SDK.

New

• Pre/Post Conditions: Define checks for resource and data source state.
• Run Tasks: Integrate remote operations (Terraform Cloud) into the post-plan stage.

Fixes Worth Knowing

• Variable Validation: Root module variables now correctly enforce type constraints and validations.
• terraform show -json: Provider configurations are now correctly mapped in JSON output.
• ignore_changes Warning: Terraform warns when adding non-optional computed attributes to ignore_changes.

Before You Upgrade

• Review the Go-TFE v1.0.0 CHANGELOG if you have custom integrations using the Go-T

TL;DR

Terraform now provides more accurate plan output by suppressing noise related to internal SDK details and resolves several crashes during planning and application.

Breaking

None

New

None

Fixes Worth Knowing

• terraform plan output is cleaner, avoiding unnecessary "Objects have changed" messages.
• Terraform is more stable; crashes during terraform plan and terraform apply are resolved, particularly when dealing with removed resources.
• State locking issues are resolved when applying a stale plan.

Before You Upgrade

None

TL;DR

Terraform now handles JSON plans with unknown values more reliably, preventing crashes during plan rendering.

Breaking

• No breaking changes in this release.

New

• No new features in this release.

Fixes Worth Knowing

• Plan rendering no longer crashes when encountering JSON plans with iterable unknown values (data structures with missing information).

Before You Upgrade

• No action needed for this upgrade.
