Statement on OpenTofu Support in AVM

[matt-FFFFFF]

To our valued Azure Verified Modules community,

As of now, Azure Verified Modules (AVM) fully supports both Bicep and Terraform. We understand that many of you are enthusiastic about OpenTofu, and we are closely monitoring developments, including potential impacts from IBM's recent acquisition of HashiCorp. However, we want to be transparent with you about our current priorities and capabilities.

Current Support and Future Considerations

We do not have the bandwidth to prioritize support at this time. Therefore, our commitment to providing a reliable and robust experience means that we must depend on OpenTofu's compatibility assurances.

Guidance for Module Authors

• We kindly request that module authors refrain from incorporating OpenTofu-specific features, as we currently lack the resources to test them effectively.
• Authors may utilize Terraform-specific features that may not be present in OpenTofu.
• To maintain broad compatibility, we advise keeping Terraform version constraints at a minimum required level for the Terraform features that you require in the module.

We deeply appreciate your understanding and continued support. Rest assured, we are evaluating our support options regularly and are committed to keeping you informed of any changes.

Update 25 Feb 2025

We continue to monitoring the OpenTofu situation. Our latest data tells us that 95% of AVM customers use the Hashicorp registry, therefore our support position is unchanged at this time.

Thank you for being an integral part of the Azure Verified Modules community.
