Aurora MySQL database engine updates 2022-01-06 (version 2.08.4) (Deprecation scheduled for September 12, 2022)

Version: 2.08.4

Aurora MySQL 2.08.4 is generally available. Aurora MySQL 2.x versions are compatible with MySQL 5.7 and Aurora MySQL 1.x versions are compatible with MySQL 5.6.

Currently supported Aurora MySQL releases are 1.19.5, 1.19.6, 1.22.*, 1.23.*, 2.04.*, 2.07.*, 2.08.*, 2.09.*, 2.10.*, 3.01.* and 3.02.*.

You can upgrade an existing Aurora MySQL 2.* database cluster to Aurora MySQL 2.10.0. For clusters running Aurora MySQL version 1, you can upgrade an existing Aurora MySQL 1.23 or higher cluster directly to 2.10.0. You can also restore a snapshot from any currently supported Aurora MySQL release into Aurora MySQL 2.10.0.

To create a cluster with an older version of Aurora MySQL, specify the engine version through the Amazon Web Services Management Console, the Amazon CLI, or the Amazon RDS API.

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

Improvements

Security fixes and general improvements:

  • Fixed security issues related to Aurora MySQL integration with other Amazon Services such as Amazon S3, Amazon ML, and Amazon Lambda.

  • Fixed an issue where the value of a TIMESTAMP column of an existing row is updated to the latest timestamp when all of the following conditions are satisfied: 1. a trigger exists for the table; 2. an INSERT is performed on the table that has an ON DUPLICATE KEY UPDATE clause; 3. the inserted row can cause a duplicate value violation in a UNIQUE index or PRIMARY KEY; and 4. one or more columns are of TIMESTAMP data type and have a default value of CURRENT_TIMESTAMP.

  • Fixed an issue which, in rare conditions, causes a writer instance to restart when an in-memory data-integrity check fails.

  • Fixed an issue with parallel query which could cause the database to restart when executing SQL statements with a LIMIT clause.
