-- `@v1.17` to use the latest patch release for the specific minor version

-### Fixed
-- Compatability with Terraform v1.0.10 - Thanks [kylewlacy](https://github.com/kylewlacy)!
-- Now makes even fewer github api requests to avoid rate limiting.
+### Added
+- A new `replace` input for [dflook/terraform-plan](https://github.com/dflook/terraform-github-actions/tree/master/terraform-plan#inputs) and [dflook/terraform-apply](https://github.com/dflook/terraform-github-actions/tree/master/terraform-apply#inputs)
+
+  This instructs terraform to replace the specified resources, and is available with terraform versions that support replace (v0.15.2 onwards).
+
+  ```yaml
+  with:
+    replace: |
+      random_password.database
+  ```
+
+- A `target` input for [dflook/terraform-plan](https://github.com/dflook/terraform-github-actions/tree/master/terraform-plan#inputs) to match [dflook/terraform-apply](https://github.com/dflook/terraform-github-actions/tree/master/terraform-apply#inputs)
+
+  `target` limits the plan to the specified resources and their dependencies. This change removes the restriction that `target` can only be used with `auto_approve`.
+
+  ```yaml
+  with:
+    target: |
+      kubernetes_secret.tls_cert_public
+      kubernetes_secret.tls_cert_private
+  ```
