To provide backwards compatibility for applications that depend on this behavior, a new option `tidb_multi_statement_mode` has been added. Assuming you understand the security risks, you can revert to the 4.0.8 by executing `SET GLOBAL tidb_multi_statement_mode='ON'`. The default behavior of `tidb_multi_statement_mode` also relaxes the error introduced in 4.0.9 to a warning. It is intended to be changed to an error again in a future release.
