## Feature Cloud SQL for MySQL 8.4 is now generally available. For more information about the differences between MySQL 8.4 and MySQL 8.0, review [What Is New in MySQL 8.4 since MySQL 8.0](https://dev.mysql.com/doc/refman/8.4/en/mysql-nutshell.html). By default, if you specify MySQL 8.4 as the version when you create a Cloud SQL instance (either primary or replica) using the gcloud CLI or the REST API, then the Cloud SQL edition is Enterprise Plus. If you specify a version other than MySQL 8.4 or don't specify a version, then the default Cloud SQL edition of the instance is Enterprise. For more information about the implementation of MySQL 8.4 in Cloud SQL, see the following topics: * [MySQL 8.4 authentication plugin default](https://cloud.google.com/sql/docs/mysql/features#mysql84-auth-plugin-default) * [MySQL features unsupported for Cloud SQL](https://cloud.google.com/sql/docs/mysql/features#unsupported-mysql-features) * [MySQL 8.4 user privileges (cloudsqlsuperuser)](https://cloud.google.com/sql/docs/mysql/users#cloudsqlsuperuser-84) To create a MySQL 8.4 instance in Cloud SQL, see [Create instances](https://cloud.google.com/sql/docs/mysql/create-instance). Before you upgrade to MySQL 8.4, you must first upgrade to MySQL 8.0.37 or later. To perform a major version upgrade, see [Upgrade the database major version in-place](https://cloud.google.com/sql/docs/mysql/upgrade-major-db-version-inplace). To perform a minor version upgrade of Cloud SQL for MySQL 8.0, see [Upgrade the database minor version](https://cloud.google.com/sql/docs/mysql/upgrade-minor-db-version).
