+### December 2021 Update Changes
+
+As of December 2021, [the ALB health check path has changed](https://github.com/1Password/scim-examples/pull/162). If you are updating from a version earlier than 2.3.0, edit your `terraform.tf` file [to use `/app` instead of `/`](https://github.com/1Password/scim-examples/pull/162/commits/a876c46b9812e96f65e42e0441a772566ca32176#) for the health check before reapplying your Terraform settings.
