 - `service` - (Required, Forces new resource, String) The type of Cloud Databases that you want to create. Only the following services are currently accepted: `databases-for-etcd`, `databases-for-postgresql`, `databases-for-redis`, `databases-for-elasticsearch`, `messages-for-rabbitmq`,`databases-for-mongodb`,`databases-for-mysql`, and `databases-for-enterprisedb`.
 - `service_endpoints` - (Required, String) Specify whether you want to enable the public, private, or both service endpoints. Supported values are `public`, `private`, or `public-and-private`.
 - `tags` (Optional, Array of Strings) A list of tags that you want to add to your instance.
-- `version` - (Optional, String) The version of the database to be provisioned. If omitted, the database is created with the most recent major and minor version. For more information, see our [versioning policy](https://cloud.ibm.com/docs/cloud-databases?topic=cloud-databases-versioning-policy).
+- `version` - (Optional, Forces new resource, String) The version of the database to be provisioned. If omitted, the database is created with the most recent major and minor version.
 - `deletion_protection` - (Optional, Boolean) If the DB instance should have deletion protection within terraform enabled. This is not a property of the resource and does not prevent deletion outside of terraform. The database can't be deleted by terraform when this value is set to `true`. The default is `false`.
 - `users` - (Optional, List of Objects) A list of users that you want to create on the database. Multiple blocks are allowed.
