Notable Changes

  • mysql_upgrade now displays a warning when upgrading a replica from MySQL Server to MariaDB Enterprise Server if data was present in the mysql.slave_master_info and mysql.slave_relay_log_info tables. A warning is needed as this information will be ignored. (MDEV-10047)

  • mysqldump has a new --ignore-table-data=<table> option. When used, the dump will include the table definition for the listed tables, but not the INSERT statements for the data in the table. (MDEV-22037)

  • mariabackup has a new --rollback-xa option. By default, mariabackup will not commit or rollback uncommitted XA transactions, and when the backup is restored any uncommitted XA transactions must be manually committed using XA COMMIT or be manually rolled-back using XA ROLLBACK. The --rollback-xa option can be used to rollback uncommitted XA transactions while performing a --prepare operation, eliminating the need for manual commit or rollback when the backup is restored. (MDEV-21168)

  • innodb_encryption_threads is now limited to 255. (MDEV-22258)

Issues Fixed

Can result in data loss

  • Possible crash with data loss when an executing an update of PRIMARY KEY columns on an InnoDB table with a BLOB column. (MDEV-22384)

Can result in a hang or crash

  • MariaDB Enterprise Backup ignored the timeout setting --ftwrl-wait-timeout when an explicit LOCK TABLES ... WRITE was active in another session. As a result, MariaDB Enterprise Server waited for release of the lock even if the timeout was reached. (MDEV-20230)

  • When additional open_table_caches_instances have been created, a crash could occur due to exceeding the limit of open file descriptors. (MDEV-18027)

Can result in unexpected behavior
