Aurora MySQL database engine updates 2019-02-07 (version 2.03.4) (Deprecated)

Version: 2.03.4

Aurora MySQL 2.03.4 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.

When creating a new Aurora MySQL DB cluster (including restoring a snapshot), you can choose compatibility with either MySQL 5.7 or MySQL 5.6.

We don't allow in-place upgrade of Aurora MySQL 1.* clusters into Aurora MySQL 2.03.4 or restore to Aurora MySQL 2.03.4 from an Amazon S3 backup. We plan to remove these restrictions in a later Aurora MySQL 2.* release.

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


This version is currently not available in the AWS GovCloud (US-West) [us-gov-west-1] and China (Beijing) [cn-north-1] regions. There will be a separate announcement once it is made available.


The procedure to upgrade your DB cluster has changed. For more information, see Upgrading the minor version or patch level of an Aurora MySQL DB cluster in the Amazon Aurora User Guide.


  • Support for UTF8MB4 Unicode 9.0 accent-sensitive and case-insensitive collation, utf8mb4_0900_as_ci.

MySQL 5.7 compatibility

Aurora MySQL 2.03.4 is wire-compatible with MySQL 5.7 and includes features such as JSON support, spatial indexes, and generated columns.
