Aurora MySQL database engine updates 2019-01-09 (version 2.03.2) (Deprecated)
Version: 2.03.2
Aurora MySQL 2.03.2 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 2.03.2 or restore to Aurora MySQL 2.03.2 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, Amazon Support is available on the community forums and through
Amazon Support
Note
This version is currently not available in the Amazon 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.
Note
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.
