 * data-source/aws_db_security_group: The `aws_redshift_service_account` data source has been deprecated and will be removed in a future version. AWS documentation [states that](https://docs.aws.amazon.com/redshift/latest/mgmt/db-auditing.html#db-auditing-bucket-permissions) a [service principal name](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements_principal.html#principal-services) should be used instead of an AWS account ID in any relevant IAM policy ([#31006](https:/hashicorp/terraform-provider-aws/issues/31006))
 * resource/aws_autoscaling_attachment: Update configurations to use `lb_target_group_arn` instead of `alb_target_group_arn` which has been removed ([#30828](https:/hashicorp/terraform-provider-aws/issues/30828))
+* resource/aws_docdb_cluster: Changes to the `snapshot_identifier` attribute will now trigger a replacement, rather than an in-place update. This corrects the previous behavior which resulted in a successful apply, but did not actually restore the cluster from the designated snapshot.
