Rasa

Improvements
- [7069](https://github.com/rasahq/rasa/issues/7069): Updated error message when using incompatible model versions.

Bugfixes
- [7885](https://github.com/rasahq/rasa/issues/7885): Limit `numpy` version to `< 1.2` as `tensorflow` is not compatible with `numpy`
versions `>= 1.2`. `pip` versions `<= 20.2` don't resolve dependencies conflicts
correctly which could result in an incompatible `numpy` version and the following
error:

bash
NotImplementedError: Cannot convert a symbolic Tensor (strided_slice_6:0) to a numpy array. This error may indicate that you're trying to pass a Tensor to a NumPy call, which is not supported

Bugfixes
- [7861](https://github.com/rasahq/rasa/issues/7861): Correctly include the `confused_with` field in the test report for the
[`POST /model/test/intents`](/pages/http-apioperation/testModelIntent) endpoint.

Bugfixes
- [7764](https://github.com/rasahq/rasa/issues/7764): Fixes a bug in [forms](forms.mdx) where the next slot asked was not consistent after returning to a form from an unhappy path.

Improvements
- [7731](https://github.com/rasahq/rasa/issues/7731): Add support for in `RasaYAMLWriter` for writing intent and example metadata back
into NLU YAML files.

Bugfixes
- [4311](https://github.com/rasahq/rasa/issues/4311): Fixed a bug with `Domain.is_domain_file()` that could raise an Exception in case the potential domain file is not a valid YAML.

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`.
