Aurora MySQL database engine updates 2019-03-25 (version 2.04.1)

Version: 2.04.1

Aurora MySQL 2.04.1 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 have the option of choosing compatibility with either MySQL 5.7 or MySQL 5.6. We do not allow in-place upgrade of Aurora MySQL 1.* clusters or restore of Aurora MySQL 1.* clusters from an Amazon S3 backup into Aurora MySQL 2.04.1. We plan to remove these restrictions in a later Aurora MySQL 2.* release.

You can restore snapshots of Aurora MySQL 1.14.*, 1.15.*, 1.16.*, 1.17.*, 1.18.*, 1.19.*, 2.01.*, 2.02.*, 2.03.*, 2.04.0 into Aurora MySQL 2.04.1.

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


This version is currently not available in the AWS GovCloud (US-West) [us-gov-west-1] region. 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.


  • Fixed an issue where an Aurora MySQL 5.6 snapshot for versions lower than 1.16 could not be restored to the latest Aurora MySQL 5.7 cluster.

Comparison with Aurora MySQL version 1

MySQL 5.7 compatibility

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