Bugfixes
- [12325](https://github.com/rasahq/rasa/issues/12325): Fix parsing of RabbitMQ URL provided in `endpoints.yml` file to include vhost path and query parameters.
Re-allows inclusion of credentials in the URL as a regression fix (this was supported in 2.x).
- [12364](https://github.com/rasahq/rasa/issues/12364): `SlotSet` events will be emitted when the value set by the custom action is the same as the existing value of the slot. This was fixed for `AugmentedMemoizationPolicy` to work properly with truncated trackers.

To restore the previous behaviour, the custom action can return a SlotSet only if the slot value has changed. For example,


class CustomAction(Action):
def name(self) -> Text:
return "custom_action"

def run(self, dispatcher: CollectingDispatcher,
tracker: Tracker,
domain: Dict[Text, Any]) -> List[Dict[Text, Any]]:
current value of the slot
slot_value = tracker.get_slot('my_slot')

value of the entity
this is parsed from the user utterance
entity_value = next(tracker.get_latest_entity_values("entity_name"), None)

if slot_value != entity_value:
return[SlotSet("my_slot", entity_value)]
