Deprecations and Removals
- #6484: NLG Server
- Changed request format to send
response as well as template as a field. The template field will be removed in Rasa Open Source 3.0.0.
rasa.core.agent
- The terminology template is deprecated and replaced by response. Support for template from the NLG response will be removed in Rasa Open Source 3.0.0. Please see [here](nlg.mdx) for more details.
rasa.core.nlg.generator
- generate() now takes in utter_action as a parameter.
- The terminology template is deprecated and replaced by response. Support for template in the NaturalLanguageGenerator will be removed in Rasa Open Source 3.0.0.
rasa.shared.core.domain
- The property templates is deprecated. Use responses instead. It will be removed in Rasa Open Source 3.0.0.
- retrieval_intent_templates will be removed in Rasa Open Source 3.0.0. Please use retrieval_intent_responses instead.
- is_retrieval_intent_template will be removed in Rasa Open Source 3.0.0. Please use is_retrieval_intent_response instead.
- check_missing_templates will be removed in Rasa Open Source 3.0.0. Please use check_missing_responses instead.
Response Selector
- The field template_name will be deprecated in Rasa Open Source 3.0.0. Please use utter_action instead. Please see [here](components.mdx#selectors) for more details.

Improvements
#7022: The following endpoints now require the existence of the conversation for the specified conversation ID, raising an exception and returning a 404 status code.
GET /conversations/<conversation_id:path>/storyPOST /conversations/<conversation_id:path>/executePOST /conversations/<conversation_id:path>/predict
#7438: Simplify our training by overwriting train_step instead of fit for our custom models.
This allows us to use the build-in callbacks from Keras, such as the
Tensorboard Callback,
which offers more functionality compared to what we had before.
:::warning
If you want to use Tensorboard for `DIETClassifier`, `ResponseSelector`, or `TEDPolicy` and log metrics after
every (mini)batch, please use 'batch' instead of 'minibatch' as 'tensorboard_log_level'.
- #7578: When
TED is configured to extract entities rasa test now evaluates them against the labels in the test stories. Results are saved in /results along with the results for the NLU components that extract entities.
- #7680: We're now running integration tests for Rasa Open Source, with initial coverage for
SQLTrackerStore (with PostgreSQL),
RedisLockStore (with Redis) and PikaEventBroker (with RabbitMQ). The integration tests are now part of our
CI, and can also be ran locally using make test-integration
(see Rasa Open Source README for more information).
- #7763: Allow tests to be located anywhere, not just in
tests directory.
- #7893: Model configuration files are now validated whether they match the expected schema.
- #7952: Speed up
YAMLStoryReader.is_key_in_yaml function by making it to check if key is in YAML without
actually parsing the text file.
- #7953: Speed up YAML parsing by reusing parsers, making the process of environment variable interpolation optional,
and by not adding duplicating implicit resolvers and YAML constructors to
ruamel.yaml
- #7955: Drastically improved finger printing time for large story graphs
- #8000: Remove console logging of conversation level F1-score and precision since these calculations were not meaningful.
Add conversation level accuracy to core policy results logged to file in story_report.json after running rasa test core or rasa test.
- #8100: Improved the [lock store](lock-stores.mdx) debug log message when the process has to
queue because other messages have to be processed before this item.
Bugfixes
- #4612: Fixed the bug that OR statements in stories would break the check whether a model needs to be retrained
- #7063: Update the spec of
POST /model/test/intents and add tests for cases when JSON is provided.
Fix the incorrect temporary file extension for the data that gets extracted from the payload provided
in the body of POST /model/test/intents request.
- #7113: Fix for the cli command rasa data convert config when migrating Mapping Policy and no rules.
Making rasa data convert config migrate correctly the Mapping Policy when no rules are available. It updates the config.yml file by removing the MappingPolicy and adding the RulePolicy instead. Also, it creates the data/rules.yml file even if empty in the case of no available rules.
- #7470: Allow to have slots with values that result to a dictionary under the key slot_was_set (in stories.yml file).
An example would be to have the following story step in stories.yml:
yaml
- slot_was_set:
- some_slot:
some_key: 'some_value'
other_key: 'other_value'
This would be allowed if the some_slot is also set accordingly in the domain.yml with type any.
- #7662: Update the fingerprinting function to recognize changes in lookup files.
- #7932: Fixed a bug when interpolating environment variables in YAML files which included $ in their value.
This led to the following stack trace:
ValueError: Error when trying to expand the environment variables in '${PASSWORD}'. Please make sure to also set these environment variables: '['$qwerty']'.

- #7949: The REQUESTED_SLOT always belongs to the currently active form.
Previously it was possible that after form switching, the REQUESTED_SLOT was for the previous form.
- #96: Update the LanguageModelFeaturizer tests to reflect new default model weights for bert, and skip all bert tests
with default model weights on CI, run bert tests with bert-base-uncased on CI instead.
