    Increased the default value of ``innodb_log_file_size`` from 96MB to 2GB.
    This change improves overall MariaDB performance, though crash recovery
    may take longer as a tradeoff. Users can adjust the value by overriding
    the ``mariadb_innodb_log_file_size_mb`` variable. The allowed range is
    4MB to 524288MB (512GB).
upgrade:

    The default value of ``innodb_log_file_size`` has increased from 96MB to
    2GB. This improves MariaDB performance but crash recovery may take longer.
    Before upgrading, ensure sufficient disk space is available for the larger
    InnoDB log file.
fixes:

    Fixed an intermittent Zuul CI failure in the MariaDB backup test.
