v1.9.0

Compare Source

We're proud to announce that OpenTofu 1.9.0 is now officially out! 🎉

This release includes a lot of major and minor new features, as well as a ton of community contributions!

The highlights are:

• for_each in provider configuration blocks: An alternate (aka "aliased") provider configuration can now have multiple dynamically-chosen instances using the for_each argument:

  provider "aws" {
    alias    = "by_region"
    for_each = var.aws_regions
  
    region = each.key
  }

  Each instance of a resource can also potentially select a different instance of the associated provider configuration, making it easier to declare infrastructure that ought to be duplicated for each region.

• -exclude planning option: similar to -target, this allows operators to tell OpenTofu to work on only a subset of the objects declared in the configuration or tracked in the state.

  tofu plan -exclude=kubernetes_manifest.crds

  While -target specifies the objects to include and skips everything not needed for the selected objects, -exclude instead specifies objects to skip. OpenTofu will exclude the selected objects and everything that depends on them.

Please take the above for a spin and let us know your feedback!

For all the features, see the related blog post or the detailed changelog.
