How to use action_restart in rasa_core version 0.10.4

I want to use action_restart build in function. Is it available in rasa_core version 0.10.4?

I recommend updating to the latest version 0.12.3 since the architecture changed quite a lot between 0.10 and 0.11. Regarding action_restart I think was present, yes. If not, you can use a custom action with a RestartedEvent(Events)
