Release notes

New features

• Support MySQL 8.0.
• Support custom backups. You can back up the cluster data to S3 or local volumes.
• Support scheduled backup to automatically back up clusters in scheduled time.
• Support defining the my.cnf parameter by users for more flexibility.
• TLS encryption is supported by the cluster server. The client can connect with the server in encrypted mode.
• Support automatic parameter adaptation. The cluster can automatically set some key parameters according to the resource quota of the Pod.
• Support automatic verification of the custom resource parameter to detect invalid parameters. For example, in MySQL 8.0, the lower_case_table_names parameter cannot be modified online.
• Support the additional print column for custom resources. For example, you can run kubectl get Clustername to obtain the leader Pod in the current cluster.
• Add the backup status record to support querying the historical backup information of the cluster.

Note: You need to manually upgrade custom resources if a historical version has already been installed locally.

Improvements

• Enhance high availability and failover reliability.
• Simplify the operator logs.
• Increase user manuals and provide English versions.
