Bugfixes
- [12361](https://github.com/rasahq/rasa/issues/12361): Explicitly handled `BufferError exception - Local: Queue full` in Kafka producer.

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)]

Bugfixes
- [12186](https://github.com/rasahq/rasa/issues/12186): Fix issue with failures while publishing events to RabbitMQ after a RabbitMQ restart.
The fix consists of pinning `aio-pika` dependency to `8.2.3`, since this issue was introduced in `aio-pika` v`8.2.4`.

Improvements
- [12144](https://github.com/rasahq/rasa/issues/12144): Add a self-reference of the synonym in the EntitySynonymMapper to handle entities extracted in a casing different to synonym case. (For example if a synonym `austria` is added, entities extracted with any alternate casing of the synonym will also be mapped to `austria`). It addresses ATO-616

Bugfixes
- [12139](https://github.com/rasahq/rasa/issues/12139): Fix 2 issues detected with the HTTP API:
- The `GET /conversations/{conversation_id}/tracker` endpoint was not returning the tracker with all sessions when `include_events` query parameter was set to `ALL`.
The fix constituted in using `TrackerStore.retrieve_full_tracker` method instead of `TrackerStore.retrieve` method in the function handling the `GET /conversations/{conversation_id}/tracker` endpoint.
Implemented or updated this method across all tracker store subclasses.
- The `GET /conversations/{conversation_id}/story` endpoint was not returning all the stories for all sessions when `all_sessions` query parameter was set to `true`.
The fix constituted in using all events of the tracker to be converted in stories instead of only the `applied_events`.
- [12189](https://github.com/rasahq/rasa/issues/12189): Make custom actions inheriting from rasa-sdk `FormValidationAction` parent class an exception of the `selective_domain` rule and always send them domain.
