 # Upgrade to 3.0
 
+## BC BREAK `Statement::execute()` with redundant parameters.
+
+Similarly to the drivers based on `pdo_pgsql` and `pdo_sqlsrv`, `OCI8Statement::execute()` and `MySQLiStatement::execute()` do not longer ignore redundant parameters.
+
 ## BC BREAK: `Doctrine\DBAL\Types\Type::getDefaultLength()` removed
 
 The `Doctrine\DBAL\Types\Type::getDefaultLength()` method has been removed as it served no purpose.
