Terraform 0.12.31 is a specific point release in the 0.12 major line that continues to appear in enterprise artifact repositories and legacy infrastructure pipelines. The version is distributed through the Chocolatey community package ecosystem and is documented alongside the broader 0.12 language evolution that redefined Terraform configuration from a simple declarative format into a more expressive programming model. Understanding 0.12.31 requires examining both the packaging metadata available via Chocolatey and the foundational language changes introduced across Terraform 0.12.

Open Source or Commercial:
- Proxy Repository - Create a proxy nuget repository on Nexus, Artifactory Pro, or a proxy Chocolatey repository on ProGet. Point your upstream to https://community.chocolatey.org/api/v2/. Packages cache on first access automatically
The package description also references core Terraform workflow concepts that remain relevant for 0.12 users:
- The execution plan shows what Terraform will do when you call apply. This lets you avoid any surprises when Terraform manipulates infrastructure.
- Resource Graph: Terraform builds a graph of all your resources, and parallelizes the creation and modification of any non-dependent resources. Because of this, Terraform builds infrastructure as efficiently as possible, and operators get insight into dependencies in their infrastructure.
- Change Automation: Complex changesets can be applied to your infrastructure with minimal human interaction. With the previously mentioned execution plan and resource graph, you know exactly what Terraform will change and in what order, avoiding many possible human errors.

What Is New in Terraform 0.12
Terraform 0.12 is a foundational release that introduces major new language features and a more robust foundation for future development. This table summarizes the key changes.
| Category | Key Changes |
|---|---|
| New Language Features | First-class expressions, generalized type system, conditional expressions, for expressions, for_each and dynamic blocks |
| Improvements | Improved interpolation, template syntax, plugin installation, and error messages |
| Backwards Incompatibilities | Required syntax changes for lists and maps, new keyword conflicts |
How did Terraform 0.12 change the core language?
The core language received its most significant upgrade, moving from a basic configuration format to a more expressive programming language. This shift enables you to write more dynamic and reusable infrastructure code.
A major change is the introduction of first-class expressions. You no longer need to wrap expressions in interpolation syntax ${...} in most places. This makes the code cleaner and less cluttered. For example, instance_type = var.type now works directly.
The new generalized type system is a big deal. It supports rich data structures and allows for stricter validation, catching type errors at plan time instead of apply time
Packaging Considerations for 0.12.31
The Chocolatey package for Terraform 0.12.31 is an Individual Install, Upgrade, & Uninstall deployment. The metadata emphasizes that the package is not affiliated with HashiCorp and is provided for community convenience.
The presence of three passing tests in the health check indicates basic validation of the package manifest. The artifact hashes for nupkg and zip files are exposed for verification. The scanning results show ## / 62 and ## / 61 indicators, reflecting community malware scanning coverage. Users relying on 0.12.31 in regulated environments should verify those hashes against internal mirrors and retain the approval date of Tuesday, April 27, 2021 for audit trails.
The organizational deployment guidance points to proxying https://community.chocolatey.org/api/v2/ through Nexus, Artifactory Pro, or ProGet. That pattern is typical for teams that need immutable access to a specific Terraform point release while remaining insulated from upstream changes.
Language Foundations Carried by 0.12.31
Terraform 0.12.31 inherits the entire 0.12 language surface. The first-class expressions change reduces the need for interpolation wrappers and simplifies configuration readability. The generalized type system brings richer validation earlier in the workflow, shifting error detection from apply time to plan time.
The for expressions, for_each, and dynamic blocks introduced in 0.12 enable meta-programming patterns that were previously cumbersome. These features are retained in 0.12.31, making the point release suitable for modules that depend on dynamic resource generation.
Improvements to interpolation, template syntax, plugin installation, and error messages also ship with 0.12.31. Backwards incompatibilities noted for 0.12, such as required syntax changes for lists and maps and new keyword conflicts, mean that configurations authored for 0.11 may require updates before running under 0.12.31.
The resource graph and execution plan capabilities referenced in the package description are core to the Terraform engine across versions, including 0.12.31. Parallelization of non-dependent resources and change automation remain central to operational safety.
Conclusion
Terraform 0.12.31 represents a stable, approved Chocolatey package snapshot of the 0.12 language era. It is dated Tuesday, April 27, 2021, carries a download count of 15880 in the Chocolatey index, and is listed with three passing health checks and artifact hashes for terraform.0.12.31.nupkg, terraform0.12.31windowsamd64.zip, and terraform0.12.31windows386.zip.
The value of 0.12.31 is not in new features beyond the 0.12 language foundation, but in providing a pinned, reproducible binary for environments that require exact version alignment. The 0.12 foundation introduced first-class expressions, a generalized type system, conditional expressions, for expressions, for_each and dynamic blocks, improved interpolation and error messages, and required syntax changes for lists and maps.
For teams maintaining legacy modules, the Chocolatey package offers an individual install and uninstall path with organizational deployment guidance via proxy repositories. The legal disclaimer clarifies no affiliation with HashiCorp, and the security scanning metadata provides baseline visibility into artifact integrity. In practice, 0.12.31 is best used where long-term stability of the 0.12 language semantics is required and where migration to later 0.13, 0.14, or 1.x lines is not yet feasible.
