Aurora MySQL database engine updates 2019-11-11 (version 2.05.0) (Deprecated)

Version: 2.05.0

Aurora MySQL 2.05.0 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 1.14.*, 1.15.*, 1.16.*, 1.17.*, 1.18.*, 1.19.*, 2.01.*, 2.02.*, 2.03.* and 2.04.*.

You can restore a snapshot from a currently supported Aurora MySQL release into Aurora MySQL 2.05.0. You also have the option to upgrade existing Aurora MySQL 2.* database clusters, up to 2.04.6, to Aurora MySQL 2.05.0. You cannot upgrade an existing Aurora MySQL 1.* cluster directly to 2.05.0; however, you can restore its snapshot to Aurora MySQL 2.05.0.

To create a cluster with an older version of Aurora MySQL, please specify the engine version through the AWS Management Console, the AWS CLI, or the RDS API.


This version is currently not available in the following AWS Regions: AWS GovCloud (US-East) [us-gov-east-1], AWS GovCloud (US-West) [us-gov-west-1], China (Ningxia) [cn-northwest-1], Asia Pacific (Hong Kong) [ap-east-1], Europe (Stockholm) [eu-north-1], and Middle East (Bahrain) [me-south-1]. There will be a separate announcement once it is made available.

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.


For information on how to upgrade your Aurora MySQL database cluster, see Upgrading the minor version or patch level of an Aurora MySQL DB cluster in the Amazon Aurora User Guide.


Critical fixes:

High-priority fixes:

  • Customers with database size close to 64 tebibytes (TiB) are strongly advised to upgrade to this version to avoid downtime due to stability bugs affecting volumes close to the Aurora storage limit.

  • The default value of the parameter aurora_binlog_replication_max_yield_seconds has been changed to zero to prevent an increase in replication lag in favor of foreground query performance on the binlog master.

Integration of MySQL bug fixes

  • Bug#23054591: PURGE BINARY LOGS TO is reading the whole binlog file and causing MySql to Stall
