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 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 instance.

Fixed an issue that, in rare conditions, can cause the reader DB instances to restart.

Fixed an issue that can cause a database instance to restart when running SHOW STATUS and PURGE BINARY LOGS statements concurrently. PURGE BINARY LOGS is a managed statement that is run to honor the user-configured binlog retention period.

Fixed an issue that can cause the server to unexpectedly close after running Data Manipulation Language (DML) statements on a table whose nonvirtual columns were reordered with a MODIFY COLUMN or CHANGE COLUMN statement.

Fixed an issue that, during the restart of a database instance, can cause an additional restart.

Fixed an issue that can cause a reader DB instance that uses write forwarding to restart when a forwarded implicit commit statement encounters an error.

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 where DB instances using multi-TB Aurora cluster volumes can experience increased downtime during restart due to InnoDB buffer pool validation failures.

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 that can interrupt database recovery during startup if the restart occurred while running heavy insert operations involving AUTO_INCREMENT columns.

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

Reduced I/O usage and improved performance for a subset of primary key range scan queries that employ parallel query.

Aurora MySQL version 3.06.0 added support for Amazon Bedrock integration. As part of this, new reserved keywords (accept, aws_bedrock_invoke_model, aws_sagemaker_invoke_endpoint, content_type, and timeout_ms) were added. In Aurora MySQL version 3.07.0, these keywords have been changed to nonreserved keywords, which are permitted as identifiers without quoting. For more information on how MySQL handles reserved and nonreserved keywords, see Keywords and reserved words in the MySQL documentation.

Fixed an issue that didn't clearly return an error message to the client when invoking the Amazon Bedrock service from an Aurora MySQL DB cluster in an Amazon Web Services Region where Amazon Bedrock isn't yet available.

Fixed an issue that can cause excessive memory consumption when querying BLOB columns using Aurora parallel query.

Added support for the connection_memory_limit and connection_memory_chunk_size parameters to be set at the session level to behave the same as in MySQL Community Edition. The connection_memory_limit is used to set the maximum amount of memory that can be used by a single user connection. The connection_memory_chunk_size parameter can be used to set the chunking size for updates to the global memory usage counter.

Fixed an issue where the user is unable to interrupt any query or set session timeouts for performance_schema queries.

Fixed an issue where binary log (binlog) replication configured to use custom SSL certificates (mysql.rds_import_binlog_ssl_material) could fail when the replication instance is undergoing a host replacement.

Added the Aurora_fts_cache_memory_used global status variable to track memory usage for the full-text search system across all tables. For more information, see Aurora MySQL global status variables in the Amazon Aurora User Guide.

Fixed an issue where an Amazon Redshift cluster configured as a zero-ETL destination might experience a temporary increase in IntegrationLag when an Amazon Aurora MySQL DB cluster is configured as a binary log replica, with Enhanced Binlog and zero-ETL integration enabled.

Fixed an issue related to audit log file management that can cause log files to be inaccessible for download or rotation, and in some cases increase CPU usage.

Optimized AUTO_INCREMENT key recovery to reduce the completion time for restoring snapshots, performing point-in-time recovery, and cloning DB clusters with large numbers of tables in the database.

Fixed an issue where the wait/io/redo_log_flush event wasn't shown in the Performance Schema wait event summary tables.

Fixed an issue that can cause duplicate key errors for AUTO_INCREMENT columns using descending indices after a snapshot restore, backtrack, or database cloning operation.

Fixed an issue that can cause a writer DB instance to restart when a reader DB instance using write forwarding runs a Data Manipulation Language (DML) statement that contains a timestamp value and the time_zone database parameter is set to UTC.

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.

Fixed an issue that, in rare cases, causes zero downtime patching (ZDP) to fail.

Fixed an issue that can cause an incomplete result set when running queries involving LEFT JOIN or RIGHT JOIN operations using the hash join algorithm with parallel query.

Fixed an issue that can cause upgrade failures from Aurora MySQL version 2 to Aurora MySQL version 3 when there is a user-defined FTS_DOC_ID column present in the table schema.

Fixed an issue that can cause upgrade failures from Aurora MySQL version 2 to Aurora MySQL version 3 due to a synchronization issue while processing InnoDB tablespaces.

Fixed an issue that can cause major version upgrades to Aurora MySQL version 3 to fail due to the presence of orphaned entries for already deleted tablespaces in InnoDB system tables in Aurora MySQL version 2.

Fixed an issue where the SERVER_ID value wasn't updated after an Amazon RDS Blue/Green Deployment switchover. This led to issues where smart drivers such as the Amazon Web Services (Amazon) JDBC Driver were unable to discover the DB cluster topology after a blue/green switchover. With this fix, Aurora DB clusters renamed as part of an RDS Blue/Green Deployment, that are running on Aurora MySQL version 3.07 and higher, will have the SERVER_ID value updated as part of the switchover. For earlier versions, the DB instances in the blue and green clusters can be rebooted to update the SERVER_ID value.

Fixed an issue where cache line value can be calculated incorrectly, causing a failure during database restart on Graviton-based instances. (Community Bug Fix #35479763)

Fixed an issue where some instances of subqueries within stored routines were not handled correctly. (Community Bug Fix #35377192)

Fixed an issue that can cause higher CPU usage due to background TLS certificate rotation (Community Bug Fix #34284186).

Fixed an issue where InnoDB allowed the addition of INSTANT columns to tables in the MySQL system schema in Aurora MySQL versions lower than 3.05, which could lead to the server unexpectedly closing (database instance restarting) after upgrading to Aurora MySQL version 3.05.0. (Community Bug Fix #35625510).
