Version: 3.04.3

Aurora MySQL 3.04.3 is generally available. Aurora MySQL 3.04 versions are compatible with MySQL 8.0.28. For more information on community changes that have occurred, see MySQL 8.0 Release Notes.

For details of the new features in Aurora MySQL version 3, see Aurora MySQL version 3 compatible with MySQL 8.0. For differences between Aurora MySQL version 3 and Aurora MySQL version 2, see Comparing Aurora MySQL version 2 and Aurora MySQL version 3. For a comparison of Aurora MySQL version 3 and MySQL 8.0 Community Edition, see Comparing Aurora MySQL version 3 and MySQL 8.0 Community Edition.

Note

This version is designated as a long-term support (LTS) release. For more information, see Aurora MySQL long-term support (LTS) releases in the Amazon Aurora User Guide.

We recommend that you don't set the AutoMinorVersionUpgrade parameter to true (or enable Auto minor version upgrade in the Amazon Web Services Management Console) for LTS versions. Doing so could lead to your DB cluster being upgraded to a non-LTS version such as 3.05.2.

Currently supported Aurora MySQL releases are 2.07.9, 2.7.10, 2.11.*, 2.12.*, 3.03.*, 3.04.*, 3.05.*, 3.06.*, and 3.07.*.

You can perform an in-place upgrade, restore a snapshot, or initiate a managed blue/green upgrade using Amazon RDS Blue/Green Deployments from any currently available Aurora MySQL version 2 cluster into an Aurora MySQL version 3.04.3 cluster.

For information on planning an upgrade to Aurora MySQL version 3, see Planning a major version upgrade for an Aurora MySQL DB cluster. For general information about Aurora MySQL upgrades, see Upgrading Amazon Aurora MySQL DB clusters in the Amazon Aurora User Guide.

For troubleshooting information, see Troubleshooting for Aurora MySQL in-place upgrade in the Amazon Aurora User Guide.

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

Improvements

Fixed security issues and CVEs:

This release includes all community CVE fixes up to and including MySQL 8.0.28. The following CVE fixes are included:

Availability improvements:

  • Fixed an issue that causes an Aurora MySQL DB instance to restart when running a parallel query.

  • Fixed an issue that can cause a reader DB instance to restart when reading a table that is being altered or dropped on the writer DB instance.

  • Fixed an issue that caused a memory access violation leading to releasing a mutex object no longer owned by the thread.

  • Fixed an issue that can cause an Aurora MySQL writer DB instance to restart when a write forwarding session is closed while running a forwarded query.

  • Fixed an issue that causes a DB instance to restart when handling large GTID sets on a binary log–enabled instance.

  • Fixed an issue when processing INSERT queries on InnoDB partitioned tables that can cause a gradual decline of free memory in the DB instance.

  • Fixed an issue that, in rare conditions, can cause a reader instance to restart when performing SELECT queries on tables with a foreign key constraint.

  • Fixed an issue that can cause a database to restart when InnoDB data dictionary recovery takes a long time during database recovery.

  • Fixed an issue that can cause a database to restart when a cascading UPDATE or DELETE foreign key constraint is defined on a table where a virtual column is involved either as a column in the foreign key constraint, or as a member of the referenced table.

  • Fixed an issue in Aurora Serverless v2 that can lead to a database restart while scaling up.

General improvements:

  • Fixed an issue that provided an incorrect value for the threads_running status variable when using Aurora Global Database.

  • Fixed an issue that causes a DB instance to restart because of inaccurate lock holder information in rw_lock when using parallel reads.

  • Fixed a memory management issue that led to a decrease in freeable memory over time when running SELECT ... INTO OUTFILE ... queries.

  • Fixed an issue that can cause a DB instance to restart when the local storage on the DB instance reaches full capacity.

  • Fixed an issue where the Performance Schema wasn't enabled when Performance Insights automated management was turned on for db.t4g.medium and db.t4g.large DB instances.

  • Fixed an issue during zero downtime patching (ZDP) that prevents a DB instance from closing client connections upon reaching the customer-configured of either wait_timeout or interactive_timeout.

  • Fixed an issue where a SELECT query on an Aurora reader instance might fail with the error table doesn't exist when the table has at least one full-text search (FTS) index and a TRUNCATE statement is being run on the Aurora writer DB instance.

Upgrades and migrations:

  • Fixed an issue that causes upgrades or migrations to fail when the target Aurora MySQL DB engine version is 3.04.0 or higher. This occurs when the lower_case_table_names DB cluster parameter is set to 1, and MySQL database collation is incompatible with lowercase table names.

Integration of MySQL Community Edition bug fixes

This release includes all community bug fixes up to and including 8.0.28. For more information, see MySQL bugs fixed by Aurora MySQL 3.x database engine updates.
