## Notable Changes

* The new mysqldump `--system={all, users, plugins, udfs, servers, stats, timezones}` command-line option allows dumping system information in logical form. ([MDEV-23630](https://jira.mariadb.org/browse/MDEV-23630))
* Added primary host and port info to replica stop messages. ([MDEV-10272](https://jira.mariadb.org/browse/MDEV-10272))
* Parameter [innodb\_idle\_flush\_pct](/docs/server/server-management/variables-and-modes/server-system-variables.md#innodb_idle_flush_pct) has no effect and is defined as deprecated. ([MDEV-24536](https://jira.mariadb.org/browse/MDEV-24536))
* New MariaDB Enterprise Backup --log-innodb-page-corruption to continue the backup process when corruption is encountered. Corrupted pages are logged in backup\_corrupted file in the backup destination directory. ([MDEV-22929](https://jira.mariadb.org/browse/MDEV-22929))
* MariaDB Enterprise Backup adds `completed with Error!` to the end of the log file if the backup is started with parameter --log-innodb-page-corruption and completed with corrupted tables. The new log entry `canceled with Error!` will be used when the backup could not be completed. (MENT-1059)
* [wsrep\_provider](/docs/server/server-management/variables-and-modes/server-system-variables.md#wsrep_provider) and [wsrep\_notify\_cmd](/docs/server/server-management/variables-and-modes/server-system-variables.md#wsrep_notify_cmd) system variables are read-only. ([MDEV-25179](https://jira.mariadb.org/browse/MDEV-25179))
