### Fixed (5.7.3 - 5.7.7) - MariaDB binlog position bug (4 vs 5 columns) - Notify test command ENV variable reading - SMTP 250 Ok response treated as error - Verify command absolute path handling - DR Drill for modern MariaDB containers: - Use mariadb-admin/mariadb client - TCP instead of socket connections - DROP DATABASE before restore ### Improved - Better --password flag error message - PostgreSQL peer auth fallback logging - Binlog warnings at DEBUG level
