Aurora MySQL database engine updates 2018-02-06 (version 2.01) (Deprecated)
Version: 2.01
Aurora MySQL 2.01 is generally available. Going forward, Aurora MySQL 2.x versions will be compatible with MySQL 5.7 and Aurora MySQL 1.x versions will be compatible with MySQL 5.6.
When creating a new Aurora MySQL DB cluster, including those restored from snapshots, you can choose compatibility with either MySQL 5.7 or MySQL 5.6.
You can restore snapshots of Aurora MySQL 1.14*, 1.15*, and 1.16* into Aurora MySQL 2.01.
We don't allow in-place upgrade of Aurora MySQL 1.x clusters into Aurora MySQL 2.01 or restore to Aurora MySQL 2.01 from an Amazon S3 backup. We plan to remove these restrictions in a later Aurora MySQL 2.x release.
The performance schema is disabled for this release of Aurora MySQL 5.7. Upgrade to Aurora 2.03 for performance schema support.
