Currently supported Aurora MySQL releases are 1.14.*, 1.15.*, 1.16.*, 1.17.*, 1.18.*, 1.19.*, 1.20.*, 1.21.*, 1.22.*, 1.23.*, 2.01.*, 2.02.*, 2.03.*, 2.04.*, 2.05.*, 2.06.*, 2.07.*, 2.08.*, and 2.09.*.

You can restore a snapshot from a currently supported Aurora MySQL release into Aurora MySQL 2.07.4. You also have the option to upgrade existing Aurora MySQL 2.* database clusters to Aurora MySQL 2.07.4. You can't upgrade an existing Aurora MySQL 1.* cluster directly to 2.07.4; however, you can restore its snapshot to Aurora MySQL 2.07.4.

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 designated as a long-term support (LTS) release. For more information, see Aurora MySQL long-term support (LTS) releases.

If you have any questions or concerns, AWS Support is available on the community forums and through AWS Premium Support. For more information, see Maintaining an Amazon Aurora DB cluster.

Improvements

Security fixes:

Availability improvements:

  • Fixed an issue that could cause a client to hang in case of a network error while reading or writing a network packet.

  • Improved engine restart times in some cases after interrupted DDL.

  • Fixed an issue where a DDL or DML could cause engine restart during a page prefetch request.

  • Fixed an issue where a replica could restart while performing a reverse scan of a table/index on an Aurora Read Replica.

  • Fixed an issue in clone cluster operation that could cause the clone to take longer.

  • Fixed an issue that could cause a restart of a database when using parallel query optimization for geo-spatial column.

  • Fixed an issue that caused a binlog replica to stop with an HA_ERR_KEY_NOT_FOUND error.

Integration of MySQL community edition bug fixes

  • Fixed an issue in the Full-text ngram parser when dealing with tokens containing ' ' (space), '%', or ','. Customers should rebuild their FTS indexes if using ngram parser. (Bug #25873310)

  • Fixed an issue that could cause engine restart during query execution with nested SQL views. (Bug #27214153, Bug #26864199)
