Bugfixes

- [12271](https://github.com/rasahq/rasa/issues/12271): Fix `BlockingIOError` when running `rasa shell` on utterances with more than 5KB of text.
- [12286](https://github.com/rasahq/rasa/issues/12286): Use `ruamel.yaml` round-trip loader in order to preserve all comments after appending `assistant_id` to `config.yml`.
- [12295](https://github.com/rasahq/rasa/issues/12295): Fix `AttributeError: 'NoneType' object has no attribute 'send_response'` caused by retrieving tracker via `GET /conversations/{conversation_id}/tracker` endpoint when `action_session_start` is customized in a custom action.
This was addressed by passing an instance of `CollectingOutputChannel` to the method retrieving the tracker from the `MessageProcessor`.

Bugfixes
- [12226](https://github.com/rasahq/rasa/issues/12226): 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`.

Miscellaneous internal changes

Improved Documentation
- [12209](https://github.com/rasahq/rasa/issues/12209): Add new Rasa Pro page in docs, together with minimal content changes.

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
- [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.
- [12193](https://github.com/rasahq/rasa/issues/12193): 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`.

Improved Documentation
- [12110](https://github.com/rasahq/rasa/issues/12110): Add documentation for secrets managers.

Bugfixes
- [12174](https://github.com/rasahq/rasa/issues/12174): Fixes training `DIETCLassifier` on the GPU.

A deterministic GPU implementation of SparseTensorDenseMatmulOp is not currently available

Improved Documentation
- [12127](https://github.com/rasahq/rasa/issues/12127): Updated `Test your assistant` section to describe the new end-to-end testing feature.
Also updated CLI and telemetry reference docs.
- [12169](https://github.com/rasahq/rasa/issues/12169): Update Compatibility Matrix.

Features
- [12053](https://github.com/rasahq/rasa/issues/12053): Add a new required key (`assistant_id`) to `config.yml` to uniquely identify assistants in deployment.
The assistant identifier is extracted from the model metadata and added to the metadata of all dialogue events.
Re-training will be required to include the assistant id in the event metadata.

If the assistant identifier is missing from the `config.yml` or the default identifier value is not replaced, a random
identifier is generated during each training.

An assistant running without an identifier will issue a warning that dialogue events without identifier metadata will be
streamed to the event broker.

Improvements
- [11998](https://github.com/rasahq/rasa/issues/11998): Add capability to send compressed body in HTTP request to action server.
Use COMPRESS_ACTION_SERVER_REQUEST=True to turn the feature on.

- [12155](https://github.com/rasahq/rasa/issues/12155): Sets a global seed for numpy, TensorFlow, keras, Python and CuDNN, to ensure consistent random number generation.

Improved Documentation
- [11893](https://github.com/rasahq/rasa/issues/11893): Clarify in the docs, how rules are designed and how to use this behaviour to abort a rule
