Aurora MySQL database engine updates 2021-11-24 (version 2.07.7) (Deprecated)

Version: 2.07.7

Aurora MySQL 2.07.7 is generally available. Aurora MySQL 2.* versions are compatible with MySQL 5.7 and Aurora MySQL 1.* 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.*.

You can restore a snapshot from a currently supported Aurora MySQL release into Aurora MySQL 2.07.7. You also have the option to upgrade existing Aurora MySQL 2.* database clusters to Aurora MySQL 2.07.7. You can't upgrade an existing Aurora MySQL 1.* cluster directly to 2.07.7; however, you can restore its snapshot to Aurora MySQL 2.07.7.

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

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.

Security fixes:

Fixes and other enhancements to fine-tune handling in a managed environment. Additional CVE fixes below:

General improvements:

  • Fixed security issues related to Aurora MySQL integration with other AWS Services such as Amazon S3, Amazon ML, Lambda.

  • Fixed an issue with incorrect reporting of an Aurora replication lag.

  • Fixed an issue which can cause a database instance restart to fail when the database has a large number of user and privilege combinations.

  • Fixed an issue which can cause general_log and slow_log tables to become inaccessible after in-place major version upgrade from Aurora MySQL 1.x (based on MySQL 5.6) to Aurora MySQL 2.x (based on MySQL 5.7).

  • Fixed an issue which, in rare conditions, can cause a reader instance to restart due to an incorrect check processing.

  • Fixed an issue which, in rare conditions, shows the "Database Load" chart in Performance Insights (PI) sessions as actively using CPU even though the sessions have finished processing and are idle.

  • Fixed an issue with parallel query which can cause the database to restart when executing SQL statements with a LIMIT clause.

  • Fixed an issue where the value of a TIMESTAMP column of an existing row is updated to the latest timestamp when all of the following conditions are satisfied: 1. A trigger exists for the table; 2. an INSERT is performed on the table that has an ON DUPLICATE KEY UPDATE clause; 3. the inserted row can cause a duplicate value violation in a UNIQUE index or PRIMARY KEY; and, 4. one or more columns are of TIMESTAMP data type and have a default value of CURRENT_TIMESTAMP.

  • Fixed an issue which, in rare conditions, can cause the database instance to restart when using XA transactions in READ COMMITTED isolation level.
