Aurora MySQL database engine updates 2024-07-19 (version 2.11.6, compatible with MySQL 5.7.12) This version has reached the end of standard support. (original) (raw)

Version: 2.11.6

Aurora MySQL 2.11.6 is generally available. Aurora MySQL 2.11 versions are compatible with MySQL 5.7.12. For more information on community changes, see Changes in MySQL 5.7.12 (2016-04-11, General Availability).

The currently supported Aurora MySQL releases are 2.07.9, 2.07.10, 2.11.*, 2.12.*, 3.01.*, 3.02.*, 3.03.*, 3.04.*, 3.05.*, 3.06.*, and 3.07.*.

You can upgrade an existing Aurora MySQL 2.* database cluster to Aurora MySQL 2.11.6. You can also restore a snapshot from any currently supported lower Aurora MySQL version 2 release into Aurora MySQL 2.11.6.

If you upgrade an Aurora MySQL global database to version 2.11.*, you must upgrade your primary and secondary DB clusters to the exact same version, including the patch level. For more information on upgrading the minor version of an Aurora global database, see Minor version upgrades.

Immediately after an in-place engine version upgrade to Aurora MySQL 2.11.* is performed, an operating system upgrade is applied automatically to all affected instances on the db.r4, db.r5, db.t2, and db.t3 DB instance classes, if the instances are running an old operating system version. In a Multi-AZ DB cluster, all of the reader instances apply the operating system upgrade first. When the operating system upgrade on the first reader instance is finished, a failover occurs and the previous writer instance is upgraded.

Note

The operating system upgrade isn't applied automatically to Aurora global databases during major version upgrades.

If you have any questions or concerns, AWS Support is available on the community forums and throughAWS Support. For more information, seeMaintaining an Amazon Aurora DB cluster in the Amazon Aurora User Guide.

General improvements:

Fixed an issue that can cause SQL statements to experience unexpected primary key violation errors or warnings on some rows when performing concurrent INSERT statements on a table that has an AUTO_INCREMENT primary key column and a unique key column, and when an INSERT statement has unique key violations on different rows.
Fixed an issue that can lead to incorrect query results when ZDR incorrectly restores session variables set as hints in queries.
Fixed an issue during Aurora Serverless v1 scaling that causes the DB instance to restart due to incorrect access to an internal data structure while finding a scaling point.
