Aurora MySQL database engine updates: 2018-03-13 (version 1.14.4) (Deprecated)

Version: 1.14.4

Aurora MySQL 1.14.4 is generally available. You can create new DB clusters in Aurora 1.14.4, using the AWS CLI or the Amazon RDS API and specifying the engine version. You have the option, but are not required, to upgrade existing 1.14.x DB clusters to Aurora 1.14.4.

With version 1.14.4 of Aurora, we are using a cluster-patching model where all nodes in an Aurora DB cluster are patched at the same time. We support zero-downtime patching, which works on a best-effort basis to preserve client connections through the patching process. For more information, see Maintaining an Amazon Aurora DB cluster in the Amazon Aurora User Guide.

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.

Zero-downtime patching

The zero-downtime patching (ZDP) feature attempts, on a best-effort basis, to preserve client connections through an engine patch. For more information about ZDP, see Using zero-downtime patching in the Amazon Aurora User Guide.
