 >    In new versions (3.3.0 and later), the logic for obtaining local variables has been modified: downstream node B can only use the OUT type output X of upstream node A if it has configured an IN type local variable X.
->    In all versions, for Switch nodes, there is no need to configure an IN type local variable X; you can directly use the OUT type output X from the upstream node A.
