+Note that prior to 0.8.5, `google_project` functioned like a data source,

+* Use the project ID directly in whatever is referencing the project, using the

+  to replace the old `policy_data` property.
+* Use the [import](/docs/import/usage.html) functionality
+  to import your pre-existing project into Terraform, where it can be referenced and
+  used just like always, keeping in mind that Terraform will attempt to undo any changes
+  made outside Terraform.

+prior to 0.8.5 will continue to function as they always have, and will not be managed by
+Terraform. Only newly added projects are affected.
