Rasa

- [11252](https://github.com/rasahq/rasa/issues/11252)

- [10482](https://github.com/rasahq/rasa/issues/10482): Adds a new optional config argument `prefix_suffix_case_sensitive` which can be set to `False` to ignore cases in prefix and suffix functions.
- [11122](https://github.com/rasahq/rasa/issues/11122): Added flag `use_gpu` to `TEDPolicy` and `UnexpecTEDIntentPolicy` that can be used to enable training on CPU even when a GPU is available.

- [11048](https://github.com/rasahq/rasa/issues/11048): Removed Python 3.6 support as [it reached its end of life in December 2021](https://www.python.org/dev/peps/pep-0494/#lifespan).

- [10675](https://github.com/rasahq/rasa/issues/10675): Fix broken conversion from Rasa JSON NLU data to Rasa YAML NLU data.

- [10808](https://github.com/rasahq/rasa/issues/10808): Fix the importing of retrieval intents when using a multidomain file with entity roles and groups.

- [10394](https://github.com/rasahq/rasa/issues/10394): Allow single tokens in rasa end-to-end test files to be annotated with multiple entities.

Some entity extractors (s.a. `RegexEntityExtractor`) can generate multiple entities from a single expression. Before this change, `rasa test` would fail in this case, because test stories could not be annotated correctly.
New annotation option is
YAML
stories:
- story: Some story
steps:
- user: |
cancel my [iphone][{"entity":"iphone", "value":"iphone"},{"entity":"smartphone", "value":"true"}{"entity":"mobile_service", "value":"true"}]
intent: cancel_contract
