Notable Items

From this version, the mariadb-dump tool adds a new sandbox command to the top of every dump file. This command cannot be interpreted by MariaDB command line client versions that do not have the sandbox command, or by MySQL command line clients, and an error will be generated in these clients. Other methods of importing the dump will work not have this issue.
