» Terraform v1.0 Compatibility Promises
The release of Terraform v1.0 represents an important milestone in the development of the Terraform language and workflow. Terraform v1.0 is a stable platform for describing and managing infrastructure.
In this release we're defining a number of Terraform behaviors that we intend to remain compatible with throughout the 1.x releases:
Our intention is that Terraform modules written for Terraform v1.0 will continue to plan and apply successfully, without required changes, throughout the v1.x releases.
We also intend that automation built around the workflow subset described in this document will work without changes in all future v1.x releases.
Finally, we intend that providers built against the currently-documented provider wire protocol will be compatible with all future Terraform v1.x releases targeting the same operating system and architecture, without the need for source code modification or binary recompilation.
In short, we aim to make upgrades between v1.x releases straightforward, requiring no changes to your configuration, no extra commands to run upgrade steps, and no changes to any automation you've set up around Terraform.
