Rasa

Bugfixes
- [7717](https://github.com/rasahq/rasa/issues/7717): Fix wrong warning `The method 'EventBroker.close' was changed to be asynchronous` when
the `EventBroker.close` was actually asynchronous.
- [7720](https://github.com/rasahq/rasa/issues/7720): Fix incremental training for cases when training data does not contain entities but `DIETClassifier` is configured to perform entity recognition also.

Now, the instance of `RasaModelData` inside `DIETClassifier` does not contain `entities` as a feature for training if there is no training data present for entity recognition.

Bugfixes
- [7603](https://github.com/rasahq/rasa/issues/7603): Fixed key-error bug on `rasa data validate stories`.

Miscellaneous internal changes
- [7711](https://github.com/rasahq/rasa/issues/7711)

Improvements
- [7520](https://github.com/rasahq/rasa/issues/7520): Improve the warning in case the [RulePolicy](policies.mdx#rule-policy) or the deprecated
[MappingPolicy](policies.mdxmapping-policy) are missing
from the model's `policies` configuration. Changed the info log to a warning as one
of this policies should be added to the model configuration.

Bugfixes
- [7692](https://github.com/rasahq/rasa/issues/7692): Explicitly specify the `crypto` extra dependency of `pyjwt` to ensure that the
`cryptography` dependency is installed. `cryptography` is strictly required to be able
to be able to verify JWT tokens.

Bugfixes
- [7622](https://github.com/rasahq/rasa/issues/7622): Correctly retrieve intent ranking from `UserUttered` even during default affirmation
action implementation.
- [7684](https://github.com/rasahq/rasa/issues/7684): Fixed a problem when using the `POST /model/test/intents` endpoint together with a
[model server](model-storage.mdxload-model-from-server). The error looked as follows:


ERROR rasa.core.agent:agent.py:327 Could not load model due to Detected inconsistent loop usage. Trying to schedule a task on a new event loop, but scheduler was created with a different event loop. Make sure there is only one event loop in use and that the scheduler is running on that one.


This also fixes a problem where testing a model from a model server would change the
production model.

Bugfixes
- [7592](https://github.com/rasahq/rasa/issues/7592): Fixed incompatibility between Rasa Open Source 2.2.x and Rasa X < 0.35.

Bugfixes
- [7557](https://github.com/rasahq/rasa/issues/7557): Fixed a problem where a [form](forms.mdx) wouldn't reject when the
`FormValidationAction` re-implemented `required_slots`.
- [7585](https://github.com/rasahq/rasa/issues/7585): Fixed an error when using the [SQLTrackerStore](tracker-stores.mdx#sqltrackerstore)
with a Postgres database and the parameter `login_db` specified.

The error was:

bash
psycopg2.errors.SyntaxError: syntax error at end of input
