Aurora MySQL database engine updates 2019-05-29 (version 2.04.4) (Deprecated)

Version: 2.04.4

Aurora MySQL 2.04.4 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.*.

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 2.04.4. 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.*, and 2.04.* into Aurora MySQL 2.04.4.

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.

Aurora MySQL 2.04.4 does not currently support the following MySQL 5.7 features:

• Group replication plugin

• Increased page size

• InnoDB buffer pool loading at startup
