title: Format differences in different versions of Terraform
body: <p>Is there a document or is there a way I can find differences in format between different versions of Terraform?
  I am looking to understand if there is a change in the tf file with different versions of terraform. Unfortunately I couldn't find in <a href="https://www.terraform.io/cloud-docs" rel="nofollow noreferrer">https://www.terraform.io/cloud-docs</a>
  Thanks in advance.</p>
