Hey Rasa Community,
Previously, we introduced Entity Roles & Groups in Rasa Open Source 1.10 as an experimental feature.
Due to the positive feedback we have received from our community, from release version 2.8.2 it will be considered a fully integrated feature in Rasa Open Source. Therefore, we have also added full support for this feature in Rasa X 0.40.0.
If you want to learn more about it, please check our documentation here.
