The article announces that Amazon Aurora now supports rolling upgrades for Operating System (OS) upgrades. This feature allows Aurora database clusters to seamlessly upgrade the OS version while maintaining read access to the data when using the Aurora cluster or reader endpoint.

Specifically, the article covers:

• Rolling upgrades automatically apply upgrades to a few reader instances at a time, enabling read traffic to continue for clusters with more than one reader instance.
• Rolling upgrades will be used for all OS upgrades, and customers can use existing AWS CLI or console commands to perform OS upgrades without additional steps.
• The feature is available in all AWS regions where Amazon Aurora is available.
• Amazon Aurora is designed for high performance, availability, and compatibility with MySQL and PostgreSQL, offering features like built-in security, continuous backups, serverless compute, read replicas, multi-Region replication, and AWS service integrations.
