I need parallel node, so I tried to add a parallel node, but I gave up soon because it seems like a lot of modifications are needed to implement parallelism.

Do you have any plans to update when to support parallel node?

If you have a version that implements a parallel node, I would appreciate any help.

There are currently no plans to support parallel nodes.
If you want to process in parallel, add multiple graphs to the same GameObject.
Or add multiple SubStateMachine or SubBehaviourTree to execute child graphs in parallel.
