Starting today, Amazon Aurora MySQL-Compatible Edition 3 (with MySQL 8.0 compatibility) will support MySQL 8.0.39. In addition to several security enhancements and bug fixes, MySQL 8.0.39 contains enhancements that improve database availability when handling large number of tables and reduce InnoDB issues related to redo logging, and index handling.
Aurora MySQL 3.08 also includes multiple availability improvements to reduce database restarts, memory management telemetry improvements with new CloudWatch metrics, major version upgrade optimizations for Aurora MySQL 2 to 3 upgrades, and general improvements around memory management and observability. For more details, refer to the Aurora MySQL 3.08 and MySQL 8.0.39 release notes.
To upgrade to Aurora MySQL 3.08, you can initiate a minor version upgrade manually by modifying your DB cluster, or you can enable the “Auto minor version upgrade” option when creating or modifying a DB cluster. This release is available in all AWS regions where Aurora MySQL is available.
