IAM basic roles Admin, Writer and Reader generally available

The Admin (roles/admin), Writer (roles/writer), and Reader (roles/reader) basic roles are generally available (GA). For more information, see Basic roles.

The legacy basic roles—Owner (roles/owner), Editor (roles/editor), and Viewer (roles/viewer)—are still available for use and are being actively maintained. However, if you need to grant a basic role, we recommend granting the Admin, Writer, or Reader role instead of a legacy basic role. This is because the newer roles support additional features, such as the use of IAM Conditions.
