# Rasa Open Source Change Log [¶](https://legacy-docs-v1.rasa.com/1.9.2/changelog/\#rasa-open-source-change-log "Permalink to this headline")

All notable changes to this project will be documented in this file.
This project adheres to [Semantic Versioning](http://semver.org/) starting with version 1.0.

## \[1.9.2\] - 2020-03-26 [¶](https://legacy-docs-v1.rasa.com/1.9.2/changelog/\#id1 "Permalink to this headline")

### Improved Documentation [¶](https://legacy-docs-v1.rasa.com/1.9.2/changelog/\#improved-documentation "Permalink to this headline")

- [#5497](https://github.com/RasaHQ/rasa/pull/5497): Fix documentation to bring back Sara.

## \[1.9.1\] - 2020-03-25 [¶](https://legacy-docs-v1.rasa.com/1.9.2/changelog/\#id3 "Permalink to this headline")

### Bugfixes [¶](https://legacy-docs-v1.rasa.com/1.9.2/changelog/\#bugfixes "Permalink to this headline")

- [#5492](https://github.com/rasahq/rasa/issues/5492): Fix an issue where the deprecated `queue` parameter for the [Pika Event Broker](https://legacy-docs-v1.rasa.com/1.9.2/api/event-brokers/#event-brokers-pika)
was ignored and Rasa Open Source published the events to the `rasa_core_events`
queue instead. Note that this does not change the fact that the `queue` argument
is deprecated in favor of the `queues` argument.

## \[1.9.0\] - 2020-03-24 [¶](https://legacy-docs-v1.rasa.com/1.9.2/changelog/\#id5 "Permalink to this headline")

### Features [¶](https://legacy-docs-v1.rasa.com/1.9.2/changelog/\#features "Permalink to this headline")

- [#5006](https://github.com/rasahq/rasa/issues/5006): Channel `hangouts` for Rasa integration with Google Hangouts Chat is now supported out-of-the-box.

- [#5389](https://github.com/rasahq/rasa/issues/5389): Add an optional path to a specific directory to download and cache the pre-trained model weights for [HFTransformersNLP](https://legacy-docs-v1.rasa.com/1.9.2/nlu/components/#hftransformersnlp).

- [#5422](https://github.com/rasahq/rasa/issues/5422): Add options `tensorboard_log_directory` and `tensorboard_log_level` to `EmbeddingIntentClassifier`,
`DIETClasifier`, `ResponseSelector`, `EmbeddingPolicy` and `TEDPolicy`.

By default `tensorboard_log_directory` is `None`. If a valid directory is provided,
metrics are written during training. After the model is trained you can take a look
at the training metrics in tensorboard. Execute `tensorboard --logdir <path-to-given-directory>`.

Metrics can either be written after every epoch (default) or for every training step.
You can specify when to write metrics using the variable `tensorboard_log_level`.
Valid values are ‘epoch’ and ‘minibatch’.

We also write down a model summary, i.e. layers with inputs and types, to the given directory.

### Improvements [¶](https://legacy-docs-v1.rasa.com/1.9.2/changelog/\#improvements "Permalink to this headline")

- [#4756](https://github.com/rasahq/rasa/issues/4756): Make response timeout configurable.
`rasa run`, `rasa shell` and `rasa x` can now be started with
`--response-timeout <int>` to configure a response timeout of `<int>` seconds.

- [#4826](https://github.com/rasahq/rasa/issues/4826): Add full retrieval intent name to message data
`ResponseSelector` will now add the full retrieval intent name
e.g. `faq/which_version` to the prediction, making it accessible
from the tracker.

- [#5258](https://github.com/rasahq/rasa/issues/5258): Added `PikaEventBroker` ( [Pika Event Broker](https://legacy-docs-v1.rasa.com/1.9.2/api/event-brokers/#event-brokers-pika)) support for publishing to
multiple queues. Messages are now published to a `fanout` exchange with name
`rasa-exchange` (see
[exchange-fanout](https://www.rabbitmq.com/tutorials/amqp-concepts.html#exchange-fanout)
for more information on `fanout` exchanges).

The former `queue` key is deprecated. Queues should now be
specified as a list in the `endpoints.yml` event broker config under a new key
`queues`. Example config:

```
event_broker:
    type: pika
    url: localhost
    username: username
    password: password
    queues:
    - queue-1
    - queue-2
    - queue-3
```

- [#5416](https://github.com/rasahq/rasa/issues/5416): Change `rasa init` to include `tests/conversation_tests.md` file by default.

- [#5446](https://github.com/rasahq/rasa/issues/5446): The endpoint `PUT /conversations/<conversation_id>/tracker/events` no longer
adds session start events (to learn more about conversation sessions, please
see [Session configuration](https://legacy-docs-v1.rasa.com/1.9.2/core/domains/#session-config)) in addition to the events which were sent in the request
payload. To achieve the old behavior send a
`GET /conversations/<conversation_id>/tracker`
request before appending events.

- [#5482](https://github.com/rasahq/rasa/issues/5482): Make `scale_loss` for intents behave the same way as in versions below `1.8`, but
only scale if some of the examples in a batch has probability of the golden label more than `0.5`.
Introduce `scale_loss` for entities in `DIETClassifier`.

### Bugfixes [¶](https://legacy-docs-v1.rasa.com/1.9.2/changelog/\#id15 "Permalink to this headline")

- [#5205](https://github.com/rasahq/rasa/issues/5205): Fixed the bug when FormPolicy was overwriting MappingPolicy prediction (e.g. `/restart`).
Priorities for [Mapping Policy](https://legacy-docs-v1.rasa.com/1.9.2/core/policies/#mapping-policy) and [Form Policy](https://legacy-docs-v1.rasa.com/1.9.2/core/policies/#form-policy) are no longer linear:
`FormPolicy` priority is 5, but its prediction is ignored if `MappingPolicy` is used for prediction.

- [#5215](https://github.com/rasahq/rasa/issues/5215): Fixed issue related to storing Python `float` values as `decimal.Decimal` objects
in DynamoDB tracker stores. All `decimal.Decimal` objects are now converted to
`float` on tracker retrieval.

Added a new docs section on [DynamoTrackerStore](https://legacy-docs-v1.rasa.com/1.9.2/api/tracker-stores/#tracker-stores-dynamo).

- [#5356](https://github.com/rasahq/rasa/issues/5356): Fixed bug where `FallbackPolicy` would always fall back if the fallback action is
`action_listen`.

- [#5361](https://github.com/rasahq/rasa/issues/5361): Fixed bug where starting or ending a response with `\n\n` led to one of the responses returned being empty.

- [#5405](https://github.com/rasahq/rasa/issues/5405): Fixes issue where model always gets retrained if multiple NLU/story files are in a
directory, by sorting the list of files.

- [#5444](https://github.com/rasahq/rasa/issues/5444): Fixed ambiguous logging in DIETClassifier by adding the name of the calling class to the log message.

### Improved Documentation [¶](https://legacy-docs-v1.rasa.com/1.9.2/changelog/\#id22 "Permalink to this headline")

- [#2237](https://github.com/rasahq/rasa/issues/2237): Restructure the “Evaluating models” documentation page and rename this page to [Testing Your Assistant](https://legacy-docs-v1.rasa.com/1.9.2/user-guide/testing-your-assistant/#testing-your-assistant).

- [#5302](https://github.com/rasahq/rasa/issues/5302): Improved documentation on how to build and deploy an action server image for use on other servers such as Rasa X deployments.

- #5340

## \[1.8.2\] - 2020-03-19 [¶](https://legacy-docs-v1.rasa.com/1.9.2/changelog/\#id25 "Permalink to this headline")

### Bugfixes [¶](https://legacy-docs-v1.rasa.com/1.9.2/changelog/\#id26 "Permalink to this headline")

- [#5438](https://github.com/rasahq/rasa/issues/5438): Fixed bug when installing rasa with `poetry`.

- [#5413](https://github.com/RasaHQ/rasa/issues/5413): Fixed bug with `EmbeddingIntentClassifier`, where results
weren’t the same as in 1.7.x. Fixed by setting weight sparsity to 0.

### Improved Documentation [¶](https://legacy-docs-v1.rasa.com/1.9.2/changelog/\#id29 "Permalink to this headline")

- [#5404](https://github.com/rasahq/rasa/issues/5404): Explain how to run commands as `root` user in Rasa SDK Docker images since version
`1.8.0`. Since version `1.8.0` the Rasa SDK Docker images does not longer run as
`root` user by default. For commands which require `root` user usage, you have to
switch back to the `root` user in your Docker image as described in
[Building an Action Server Image](https://legacy-docs-v1.rasa.com/1.9.2/user-guide/docker/deploying-in-docker-compose/#building-an-action-server-image).

- [#5402](https://github.com/RasaHQ/rasa/issues/5402): Made improvements to Building Assistants tutorial

## \[1.8.1\] - 2020-03-06 [¶](https://legacy-docs-v1.rasa.com/1.9.2/changelog/\#id32 "Permalink to this headline")

### Bugfixes [¶](https://legacy-docs-v1.rasa.com/1.9.2/changelog/\#id33 "Permalink to this headline")

- [#5354](https://github.com/rasahq/rasa/issues/5354): Fixed issue with using language models like `xlnet` along with `entity_recognition` set to `True` inside
`DIETClassifier`.

### Miscellaneous internal changes [¶](https://legacy-docs-v1.rasa.com/1.9.2/changelog/\#id35 "Permalink to this headline")

- #5330, #5348

## \[1.8.0\] - 2020-02-26 [¶](https://legacy-docs-v1.rasa.com/1.9.2/changelog/\#id36 "Permalink to this headline")

### Deprecations and Removals [¶](https://legacy-docs-v1.rasa.com/1.9.2/changelog/\#deprecations-and-removals "Permalink to this headline")

- [#4991](https://github.com/rasahq/rasa/issues/4991): Removed `Agent.continue_training` and the `dump_flattened_stories` parameter
from `Agent.persist`.

- [#5266](https://github.com/rasahq/rasa/issues/5266): Properties `Component.provides` and `Component.requires` are deprecated.
Use `Component.required_components()` instead.

### Features [¶](https://legacy-docs-v1.rasa.com/1.9.2/changelog/\#id39 "Permalink to this headline")

- [#2674](https://github.com/rasahq/rasa/issues/2674): Add default value `__other__` to `values` of a `CategoricalSlot`.

All values not mentioned in the list of values of a `CategoricalSlot`
will be mapped to `__other__` for featurization.

- [#4088](https://github.com/rasahq/rasa/issues/4088): Add story structure validation functionality (e.g. rasa data validate stories –max-history 5).

- [#5065](https://github.com/rasahq/rasa/issues/5065): Add [LexicalSyntacticFeaturizer](https://legacy-docs-v1.rasa.com/1.9.2/nlu/components/#lexicalsyntacticfeaturizer) to sparse featurizers.

`LexicalSyntacticFeaturizer` does the same featurization as the `CRFEntityExtractor`. We extracted the
featurization into a separate component so that the features can be reused and featurization is independent from the
entity extraction.

- [#5187](https://github.com/rasahq/rasa/issues/5187): Integrate language models from HuggingFace’s [Transformers](https://github.com/huggingface/transformers) Library.

Add a new NLP component [HFTransformersNLP](https://legacy-docs-v1.rasa.com/1.9.2/nlu/components/#hftransformersnlp) which tokenizes and featurizes incoming messages using a specified
pre-trained model with the Transformers library as the backend.
Add [LanguageModelTokenizer](https://legacy-docs-v1.rasa.com/1.9.2/nlu/components/#languagemodeltokenizer) and [LanguageModelFeaturizer](https://legacy-docs-v1.rasa.com/1.9.2/nlu/components/#languagemodelfeaturizer) which use the information from
[HFTransformersNLP](https://legacy-docs-v1.rasa.com/1.9.2/nlu/components/#hftransformersnlp) and sets them correctly for message object.
Language models currently supported: BERT, OpenAIGPT, GPT-2, XLNet, DistilBert, RoBERTa.

- [#5225](https://github.com/rasahq/rasa/issues/5225): Added a new CLI command `rasa export` to publish tracker events from a persistent
tracker store using an event broker. See [Export Conversations to an Event Broker](https://legacy-docs-v1.rasa.com/1.9.2/user-guide/command-line-interface/#section-export), [Tracker Stores](https://legacy-docs-v1.rasa.com/1.9.2/api/tracker-stores/#tracker-stores)
and [Event Brokers](https://legacy-docs-v1.rasa.com/1.9.2/api/event-brokers/#event-brokers) for more details.

- [#5230](https://github.com/rasahq/rasa/issues/5230): Refactor how GPU and CPU environments are configured for TensorFlow 2.0.

Please refer to the [documentation](https://legacy-docs-v1.rasa.com/1.9.2/api/tensorflow_usage/#tensorflow-usage) to understand
which environment variables to set in what scenarios. A couple of examples are shown below as well:

```
# This specifies to use 1024 MB of memory from GPU with logical ID 0 and 2048 MB of memory from GPU with logical ID 1
TF_GPU_MEMORY_ALLOC="0:1024, 1:2048"

# Specifies that at most 3 CPU threads can be used to parallelize multiple non-blocking operations
TF_INTER_OP_PARALLELISM_THREADS="3"

# Specifies that at most 2 CPU threads can be used to parallelize a particular operation.
TF_INTRA_OP_PARALLELISM_THREADS="2"
```

- [#5266](https://github.com/rasahq/rasa/issues/5266): Added a new NLU component [DIETClassifier](https://legacy-docs-v1.rasa.com/1.9.2/nlu/components/#diet-classifier) and a new policy [TEDPolicy](https://legacy-docs-v1.rasa.com/1.9.2/core/policies/#ted-policy).

DIET (Dual Intent and Entity Transformer) is a multi-task architecture for intent classification and entity
recognition. You can read more about this component in our [documentation](https://legacy-docs-v1.rasa.com/1.9.2/nlu/components/#diet-classifier).
The new component will replace the [EmbeddingIntentClassifier](https://legacy-docs-v1.rasa.com/1.9.2/nlu/components/#embedding-intent-classifier) and the
[CRFEntityExtractor](https://legacy-docs-v1.rasa.com/1.9.2/nlu/components/#crfentityextractor) in the future.
Those two components are deprecated from now on.
See [migration guide](https://legacy-docs-v1.rasa.com/1.9.2/migration-guide/#migration-to-rasa-1-8) for details on how to
switch to the new component.

[TEDPolicy](https://legacy-docs-v1.rasa.com/1.9.2/core/policies/#ted-policy) is the new name for [EmbeddingPolicy](https://legacy-docs-v1.rasa.com/1.9.2/core/policies/#embedding-policy).
`EmbeddingPolicy` is deprecated from now on.
The functionality of `TEDPolicy` and `EmbeddingPolicy` is the same.
Please update your configuration file to use the new name for the policy.

- [#663](https://github.com/rasahq/rasa/issues/663): The sentence vector of the `SpacyFeaturizer` and `MitieFeaturizer` can be calculated using max or mean pooling.

To specify the pooling operation, set the option `pooling` for the `SpacyFeaturizer` or the `MitieFeaturizer`
in your configuration file. The default pooling operation is `mean`. The mean pooling operation also does not take
into account words, that do not have a word vector.
See our [documentation](https://legacy-docs-v1.rasa.com/1.9.2/nlu/components/#components) for more details.

### Improvements [¶](https://legacy-docs-v1.rasa.com/1.9.2/changelog/\#id48 "Permalink to this headline")

- [#3975](https://github.com/rasahq/rasa/issues/3975): Added command line argument `--conversation-id` to `rasa interactive`.
If the argument is not given, `conversation_id` defaults to a random uuid.

- [#4653](https://github.com/rasahq/rasa/issues/4653): Added a new command-line argument `--init-dir` to command `rasa init` to specify
the directory in which the project is initialised.

- [#4682](https://github.com/rasahq/rasa/issues/4682): Added support to send images with the twilio output channel.

- [#4817](https://github.com/rasahq/rasa/issues/4817): Part of Slack sanitization:
Multiple garbled URL’s in a string coming from slack will be converted into actual strings.
`Example: health check of <http://eemdb.net|eemdb.net> and <http://eemdb1.net|eemdb1.net> to health check of
eemdb.net and eemdb1.net`

- [#5117](https://github.com/rasahq/rasa/issues/5117): New command-line argument –conversation-id will be added and wiil give the ability to
set specific conversation ID for each shell session, if not passed will be random.

- [#5211](https://github.com/rasahq/rasa/issues/5211): Messages sent to the [Pika Event Broker](https://legacy-docs-v1.rasa.com/1.9.2/api/event-brokers/#event-brokers-pika) are now persisted. This guarantees
the RabbitMQ will re-send previously received messages after a crash. Note that this
does not help for the case where messages are sent to an unavailable RabbitMQ instance.

- [#5250](https://github.com/rasahq/rasa/issues/5250): Added support for mattermost connector to use bot accounts.

- [#5266](https://github.com/rasahq/rasa/issues/5266): We updated our code to TensorFlow 2.

- [#5317](https://github.com/rasahq/rasa/issues/5317): Events exported using `rasa export` receive a message header if published through a
`PikaEventBroker`. The header is added to the message’s `BasicProperties.headers`
under the `rasa-export-process-id` key
(`rasa.core.constants.RASA_EXPORT_PROCESS_ID_HEADER_NAME`). The value is a
UUID4 generated at each call of `rasa export`. The resulting header is a key-value
pair that looks as follows:

```
'rasa-export-process-id': 'd3b3d3ffe2bd4f379ccf21214ccfb261'
```

- [#5292](https://github.com/rasahq/rasa/issues/5292): Added `followlinks=True` to os.walk calls, to allow the use of symlinks in training, NLU and domain data.

- [#4811](https://github.com/rasahq/rasa/issues/4811): Support invoking a `SlackBot` by direct messaging or `@<app name>` mentions.

### Bugfixes [¶](https://legacy-docs-v1.rasa.com/1.9.2/changelog/\#id60 "Permalink to this headline")

- [#4006](https://github.com/rasahq/rasa/issues/4006): Fixed timestamp parsing warning when using DucklingHTTPExtractor

- [#4601](https://github.com/rasahq/rasa/issues/4601): Fixed issue with `action_restart` getting overridden by `action_listen` when the `MappingPolicy` and the
[TwoStageFallbackPolicy](/content/docs/rasa/core/policies/#two-stage-fallback-policy/index.html) are used together.

- [#5201](https://github.com/rasahq/rasa/issues/5201): Fixed incorrectly raised Error encountered in pipelines with a `ResponseSelector` and NLG.

When NLU training data is split before NLU pipeline comparison,
NLG responses were not also persisted and therefore training for a pipeline including the `ResponseSelector` would fail.

NLG responses are now persisted along with NLU data to a `/train` directory in the `run_x/xx%_exclusion` folder.

- [#5277](https://github.com/rasahq/rasa/issues/5277): Fixed sending custom json with Twilio channel

### Improved Documentation [¶](https://legacy-docs-v1.rasa.com/1.9.2/changelog/\#id65 "Permalink to this headline")

- [#5174](https://github.com/rasahq/rasa/issues/5174): Updated the documentation to properly suggest not to explicitly add utterance actions to the domain.

- [#5189](https://github.com/rasahq/rasa/issues/5189): Added user guide for reminders and external events, including `reminderbot` demo.

### Miscellaneous internal changes [¶](https://legacy-docs-v1.rasa.com/1.9.2/changelog/\#id68 "Permalink to this headline")

- #3923, #4597, #4903, #5180, #5189, #5266, #699

## \[1.7.4\] - 2020-02-24 [¶](https://legacy-docs-v1.rasa.com/1.9.2/changelog/\#id69 "Permalink to this headline")

### Bugfixes [¶](https://legacy-docs-v1.rasa.com/1.9.2/changelog/\#id70 "Permalink to this headline")

- [#5068](https://github.com/rasahq/rasa/issues/5068): Tracker stores supporting conversation sessions (`SQLTrackerStore` and
`MongoTrackerStore`) do not save the tracker state to database immediately after
starting a new conversation session. This leads to the number of events being saved
in addition to the already-existing ones to be calculated correctly.

This fixes `action_listen` events being saved twice at the beginning of
conversation sessions.

## \[1.7.3\] - 2020-02-21 [¶](https://legacy-docs-v1.rasa.com/1.9.2/changelog/\#id72 "Permalink to this headline")

### Bugfixes [¶](https://legacy-docs-v1.rasa.com/1.9.2/changelog/\#id73 "Permalink to this headline")

- [#5231](https://github.com/rasahq/rasa/issues/5231): Fix segmentation fault when running `rasa train` or `rasa shell`.

### Improved Documentation [¶](https://legacy-docs-v1.rasa.com/1.9.2/changelog/\#id75 "Permalink to this headline")

- [#5286](https://github.com/rasahq/rasa/issues/5286): Fix doc links on “Deploying your Assistant” page

## \[1.7.2\] - 2020-02-13 [¶](https://legacy-docs-v1.rasa.com/1.9.2/changelog/\#id77 "Permalink to this headline")

### Bugfixes [¶](https://legacy-docs-v1.rasa.com/1.9.2/changelog/\#id78 "Permalink to this headline")

- [#5197](https://github.com/rasahq/rasa/issues/5197): Fixed incompatibility of Oracle with the [SQLTrackerStore](https://legacy-docs-v1.rasa.com/1.9.2/api/tracker-stores/#sql-tracker-store), by using a `Sequence`
for the primary key columns. This does not change anything for SQL databases other than Oracle.
If you are using Oracle, please create a sequence with the instructions in the [SQLTrackerStore](https://legacy-docs-v1.rasa.com/1.9.2/api/tracker-stores/#sql-tracker-store) docs.

### Improved Documentation [¶](https://legacy-docs-v1.rasa.com/1.9.2/changelog/\#id80 "Permalink to this headline")

- [#5197](https://github.com/rasahq/rasa/issues/5197): Added section on setting up the SQLTrackerStore with Oracle

- [#5210](https://github.com/rasahq/rasa/issues/5210): Renamed “Running the Server” page to “Configuring the HTTP API”

## \[1.7.1\] - 2020-02-11 [¶](https://legacy-docs-v1.rasa.com/1.9.2/changelog/\#id83 "Permalink to this headline")

### Bugfixes [¶](https://legacy-docs-v1.rasa.com/1.9.2/changelog/\#id84 "Permalink to this headline")

- [#5106](https://github.com/rasahq/rasa/issues/5106): Fixed file loading of non proper UTF-8 story files, failing properly when checking for
story files.

- [#5162](https://github.com/rasahq/rasa/issues/5162): Fix problem with multi-intents.
Training with multi-intents using the `CountVectorsFeaturizer` together with `EmbeddingIntentClassifier` is
working again.

- [#5171](https://github.com/rasahq/rasa/issues/5171): Fix bug `ValueError: Cannot concatenate sparse features as sequence dimension does not match`.

When training a Rasa model that contains responses for just some of the intents, training was failing.
Fixed the featurizers to return a consistent feature vector in case no response was given for a specific message.

- [#5199](https://github.com/rasahq/rasa/issues/5199): If no text features are present in `EmbeddingIntentClassifier` return the intent `None`.

- [#5216](https://github.com/rasahq/rasa/issues/5216): Resolve version conflicts: Pin version of cloudpickle to ~=1.2.0.

## \[1.7.0\] - 2020-01-29 [¶](https://legacy-docs-v1.rasa.com/1.9.2/changelog/\#id90 "Permalink to this headline")

### Deprecations and Removals [¶](https://legacy-docs-v1.rasa.com/1.9.2/changelog/\#id91 "Permalink to this headline")

- [#4964](https://github.com/rasahq/rasa/issues/4964): The endpoint `/conversations/<conversation_id>/execute` is now deprecated. Instead, users should use
the `/conversations/<conversation_id>/trigger_intent` endpoint and thus trigger intents instead of actions.

- [#4978](https://github.com/rasahq/rasa/issues/4978): Remove option `use_cls_token` from tokenizers and option `return_sequence` from featurizers.

By default all tokenizer add a special token (`__CLS__`) to the end of the list of tokens.
This token will be used to capture the features of the whole utterance.

The featurizers will return a matrix of size (number-of-tokens x feature-dimension) by default.
This allows to train sequence models.
However, the feature vector of the `__CLS__` token can be used to train non-sequence models.
The corresponding classifier can decide what kind of features to use.

### Features [¶](https://legacy-docs-v1.rasa.com/1.9.2/changelog/\#id94 "Permalink to this headline")

- [#400](https://github.com/rasahq/rasa/issues/400): Rename `templates` key in domain to `responses`.

`templates` key will still work for backwards compatibility but will raise a future warning.

- [#4902](https://github.com/rasahq/rasa/issues/4902): Added a new configuration parameter, `ranking_length` to the `EmbeddingPolicy`, `EmbeddingIntentClassifier`,
and `ResponseSelector` classes.

- [#4964](https://github.com/rasahq/rasa/issues/4964): External events and reminders now trigger intents (and entities) instead of actions.

Add new endpoint `/conversations/<conversation_id>/trigger_intent`, which lets the user specify an intent and a
list of entities that is injected into the conversation in place of a user message. The bot then predicts and
executes a response action.

- [#4978](https://github.com/rasahq/rasa/issues/4978): Add `ConveRTTokenizer`.

The tokenizer should be used whenever the `ConveRTFeaturizer` is used.

Every tokenizer now supports the following configuration options:
`intent_tokenization_flag`: Flag to check whether to split intents (default `False`).
`intent_split_symbol`: Symbol on which intent should be split (default `_`)

### Improvements [¶](https://legacy-docs-v1.rasa.com/1.9.2/changelog/\#id99 "Permalink to this headline")

- [#1988](https://github.com/rasahq/rasa/issues/1988): Remove the need of specifying utter actions in the `actions` section explicitly if these actions are already
listed in the `templates` section.

- [#4877](https://github.com/rasahq/rasa/issues/4877): Entity examples that have been extracted using an external extractor are excluded
from Markdown dumping in `MarkdownWriter.dumps()`. The excluded external extractors
are `DucklingHTTPExtractor` and `SpacyEntityExtractor`.

- [#4902](https://github.com/rasahq/rasa/issues/4902): The `EmbeddingPolicy`, `EmbeddingIntentClassifier`, and `ResponseSelector` now by default normalize confidence
levels over the top 10 results. See [Rasa 1.6 to Rasa 1.7](https://legacy-docs-v1.rasa.com/1.9.2/migration-guide/#migration-to-rasa-1-7) for more details.

- [#4964](https://github.com/rasahq/rasa/issues/4964): `ReminderCancelled` can now cancel multiple reminders if no name is given. It still cancels a single
reminder if the reminder’s name is specified.

### Bugfixes [¶](https://legacy-docs-v1.rasa.com/1.9.2/changelog/\#id104 "Permalink to this headline")

- [#4774](https://github.com/rasahq/rasa/issues/4774): Requests to `/model/train` do not longer block other requests to the Rasa server.

- [#4896](https://github.com/rasahq/rasa/issues/4896): Fixed default behavior of `rasa test core --evaluate-model-directory` when called without `--model`. Previously, the latest model file was used as `--model`. Now the default model directory is used instead.

New behavior of `rasa test core --evaluate-model-directory` when given an existing file as argument for `--model`: Previously, this led to an error. Now a warning is displayed and the directory containing the given file is used as `--model`.

- [#5040](https://github.com/rasahq/rasa/issues/5040): Updated the dependency `networkx` from 2.3.0 to 2.4.0. The old version created incompatibilities when using pip.

There is an imcompatibility between Rasa dependecy requests 2.22.0 and the own depedency from Rasa for networkx raising errors upon pip install. There is also a bug corrected in `requirements.txt` which used `~=` instead of `==`. All of these are fixed using networkx 2.4.0.

- [#5057](https://github.com/rasahq/rasa/issues/5057): Fixed compatibility issue with Microsoft Bot Framework Emulator if `service_url` lacked a trailing `/`.

- [#5092](https://github.com/rasahq/rasa/issues/5092): DynamoDB tracker store decimal values will now be rounded on save. Previously values exceeding 38 digits caused an unhandled error.

## \[1.6.0\] - 2019-12-18 [¶](https://legacy-docs-v1.rasa.com/1.9.2/changelog/\#id124 "Permalink to this headline")

### Deprecations and Removals [¶](https://legacy-docs-v1.rasa.com/1.9.2/changelog/\#id125 "Permalink to this headline")

- [#4935](https://github.com/rasahq/rasa/issues/4935): Removed `ner_features` as a feature name from `CRFEntityExtractor`, use `text_dense_features` instead.

The following settings match the previous `NGramFeaturizer`:

```
- name: 'CountVectorsFeaturizer'
    analyzer: 'char_wb'
    min_ngram: 3
    max_ngram: 17
    max_features: 10
    min_df: 5
```

- [#4957](https://github.com/rasahq/rasa/issues/4957): To use custom features in the `CRFEntityExtractor` use `text_dense_features` instead of `ner_features`. If
`text_dense_features` are present in the feature set, the `CRFEntityExtractor` will automatically make use of
them. Just make sure to add a dense featurizer in front of the `CRFEntityExtractor` in your pipeline and set the
flag `return_sequence` to `True` for that featurizer.
See [https://rasa.com/docs/rasa/nlu/entity-extraction/#passing-custom-features-to-crfentityextractor](/content/docs/rasa/nlu/entity-extraction/#passing-custom-features-to-crfentityextractor/index.html).

- [#4990](https://github.com/rasahq/rasa/issues/4990): Deprecated `Agent.continue_training`. Instead, a model should be retrained.

- [#684](https://github.com/rasahq/rasa/issues/684): Specifying lookup tables directly in the NLU file is now deprecated. Please specify
them in an external file.

### Features [¶](https://legacy-docs-v1.rasa.com/1.9.2/changelog/\#id130 "Permalink to this headline")

- [#4795](https://github.com/rasahq/rasa/issues/4795): Replaced the warnings about missing templates, intents etc. in validator.py by debug messages.

- [#4830](https://github.com/rasahq/rasa/issues/4830): Added conversation sessions to trackers.

A conversation session represents the dialog between the assistant and a user.
Conversation sessions can begin in three ways: 1. the user begins the conversation
with the assistant, 2. the user sends their first message after a configurable period
of inactivity, or 3. a manual session start is triggered with the `/session_start`
intent message. The period of inactivity after which a new conversation session is
triggered is defined in the domain using the `session_expiration_time` key in the
`session_config` section. The introduction of conversation sessions comprises the
following changes:

- Added a new event `SessionStarted` that marks the beginning of a new conversation
    session.

- Added a new default action `ActionSessionStart`. This action takes all
    `SlotSet` events from the previous session and applies it to the next session.

- Added a new default intent `session_start` which triggers the start of a new
    conversation session.

- `SQLTrackerStore` and `MongoTrackerStore` only retrieve
    events from the last session from the database.

Note

The session behaviour is disabled for existing projects, i.e. existing domains
without session config section.

- [#4935](https://github.com/rasahq/rasa/issues/4935): Preparation for an upcoming change in the `EmbeddingIntentClassifier`:

Add option `use_cls_token` to all tokenizers. If it is set to `True`, the token `__CLS__` will be added to
the end of the list of tokens. Default is set to `False`. No need to change the default value for now.

Add option `return_sequence` to all featurizers. By default all featurizers return a matrix of size
(1 x feature-dimension). If the option `return_sequence` is set to `True`, the corresponding featurizer will return
a matrix of size (token-length x feature-dimension). See [https://rasa.com/docs/rasa/nlu/components/#featurizers](/content/docs/rasa/nlu/components/#featurizers/index.html).
Default value is set to `False`. However, you might want to set it to `True` if you want to use custom features
in the `CRFEntityExtractor`.
See [https://rasa.com/docs/rasa/nlu/entity-extraction/#passing-custom-features-to-crfentityextractor](/content/docs/rasa/nlu/entity-extraction/#passing-custom-features-to-crfentityextractor/index.html).

Changed some featurizers to use sparse features, which should reduce memory usage with large amounts of training data significantly.

Warning

These changes break model compatibility. You will need to retrain your old models!

### Improvements [¶](https://legacy-docs-v1.rasa.com/1.9.2/changelog/\#id134 "Permalink to this headline")

- [#3549](https://github.com/rasahq/rasa/issues/3549): Added `--no-plot` option for `rasa test` command, which disables rendering of confusion matrix and histogram. By default plots will be rendered.

- [#4734](https://github.com/rasahq/rasa/issues/4734): Changed `url``__init__()` arguments for custom tracker stores to `host` to reflect the `__init__` arguments of
currently supported tracker stores. Note that in `endpoints.yml`, these are still declared as `url`.

- [#4751](https://github.com/rasahq/rasa/issues/4751): The `kafka-python` dependency has become as an “extra” dependency. To use the
`KafkaEventConsumer`, `rasa` has to be installed with the `[kafka]` option, i.e.

```
$ pip install rasa[kafka]
```

- [#4801](https://github.com/rasahq/rasa/issues/4801): Allow creation of natural language interpreter and generator by classname reference

Interactive learning no longer trains NLU-only models if no model is provided
and no core data is provided.

- [#4899](https://github.com/rasahq/rasa/issues/4899): The `intent_report.json` created by `rasa test` now creates an extra field
`confused_with` for each intent. This is a dictionary containing the names of
the most common false positives when this intent should be predicted, and the
number of such false positives.

- [#4976](https://github.com/rasahq/rasa/issues/4976): `rasa test nlu --cross-validation` now also includes an evaluation of the response selector.
As a result, the train and test F1-score, accuracy and precision is logged for the response selector.
A report is also generated in the `results` folder by the name `response_selection_report.json`

### Bugfixes [¶](https://legacy-docs-v1.rasa.com/1.9.2/changelog/\#id144 "Permalink to this headline")

- [#4635](https://github.com/rasahq/rasa/issues/4635): If a `wait_time_between_pulls` is configured for the model server in `endpoints.yml`,
this will be used instead of the default one when running Rasa X.

- add flag to CLI to persist NLU training data if needed

- log a warning if the `Interpreter` picks up an intent or an entity that does not
exist in the domain file.

- added `DynamoTrackerStore` to support persistence of agents running on AWS

- added docstrings for `TrackerStore` classes

- added buttons and images to mattermost.

- `CRFEntityExtractor` updated to accept arbitrary token-level features like word
vectors (issues/4214)

- `SpacyFeaturizer` updated to add `ner_features` for `CRFEntityExtractor`

- Sanitizing incoming messages from slack to remove slack formatting like < [mailto:xyz@rasa](mailto:xyz%40rasa).com\|xyz@rasa.com>
or < [http://url](http://url/).com\|url.com> and substitute it with original content

- Added the ability to configure the number of Sanic worker processes in the HTTP
server (`rasa.server`) and input channel server
(`rasa.core.agent.handle_channels()`). The number of workers can be set using the
environment variable `SANIC_WORKERS` (default: 1). A value of >1 is allowed only in
combination with `RedisLockStore` as the lock store.

- Botframework channel can handle uploaded files in `UserMessage` metadata.

- Added data validator that checks there is no duplicated example data across multiples intents

### Improvements [¶](https://legacy-docs-v1.rasa.com/1.9.2/changelog/\#id197 "Permalink to this headline")

- Unknown sections in markdown format (NLU data) are not ignored anymore, but instead an error is raised.

- It is now easier to add metadata to a `UserMessage` in existing channels.
You can do so by overwriting the method `get_metadata`. The return value of this
method will be passed to the `UserMessage` object.

- Tests can now be run in parallel

- Serialise `DialogueStateTracker` as json instead of pickle. **DEPRECATION warning**:
Deserialisation of pickled trackers will be deprecated in version 2.0. For now,
trackers are still loaded from pickle but will be dumped as json in any subsequent
save operations.

- Event brokers are now also passed to custom tracker stores (using the `event_broker` parameter)

- Don’t run the Rasa Docker image as `root`.

- Use multi-stage builds to reduce the size of the Rasa Docker image.

- Updated the `/status` api route to use the actual model file location instead of the `tmp` location.

### Features [¶](https://legacy-docs-v1.rasa.com/1.9.2/changelog/\#id216 "Permalink to this headline")

- Added the ability to set the `backlog` parameter in Sanics `run()` method using
the `SANIC_BACKLOG` environment variable. This parameter sets the
number of unaccepted connections the server allows before refusing new
connections. A default value of 100 is used if the variable is not set.

empty strings as discussed [here](https://github.com/RasaHQ/rasa/issues/4445).
Only training samples that actually bear content are sent to `self.nlp.pipe`
for every given attribute. Non-content-bearing samples are converted to empty
`Doc`-objects. The resulting lists are merged with their preserved order and
properly returned.

- asyncio warnings are now only printed if the callback takes more than 100ms
(up from 1ms).

- `agent.load_model_from_server` no longer affects logging.

### Improvements [¶](https://legacy-docs-v1.rasa.com/1.9.2/changelog/\#id218 "Permalink to this headline")

for the trained model using the field `out`. Instead you can choose whether you
want to save the trained model in the default model directory (`models`)
(default behavior) or in a temporary directory by specifying the
`save_to_default_model_directory` field in the training request.

## \[1.3.3\] - 2019-09-13 [¶](https://legacy-docs-v1.rasa.com/1.9.2/changelog/\#id219 "Permalink to this headline")

the training data.

- Default one-hot representation for label featurization inside `EmbeddingIntentClassifier` if label features don’t exist.

- Policy ensemble no longer incorrectly wrings “missing mapping policy” when
mapping policy is present.

`MappingPolicy` being present in the policy ensemble

- The tracker is now available within the interpreter’s `parse` method, giving the
ability to create interpreter classes that use the tracker state (eg. slot values)
during the parsing of the message. More details on motivation of this change see
issues/3015.

- add example bot `knowledgebasebot` to showcase the usage of `ActionQueryKnowledgeBase`

- `softmax` starspace loss for both `EmbeddingPolicy` and `EmbeddingIntentClassifier`

- `balanced` batching strategy for both `EmbeddingPolicy` and `EmbeddingIntentClassifier`

the runtime configuration (endpoints and credentials)

- `LockStore` class storing instances of `TicketLock` for every `conversation_id`

- environment variables `SQL_POOL_SIZE` (default: 50) and `SQL_MAX_OVERFLOW`

`SQLTrackerStore` when used with the `postgresql` dialect

- Add a bot\_challenge intent and a utter\_iamabot action to all example projects and the rasa init bot.

- Allow sending attachments when using the socketio channel

- `rasa data validate` will fail with a non-zero exit code if validation fails

### Improvements [¶](https://legacy-docs-v1.rasa.com/1.9.2/changelog/\#id228 "Permalink to this headline")

into the `supervised_embeddings` NLU pipeline template

- NLU evaluations now also stores its output in the output directory like the core evaluation

- show warning in case a default path is used instead of a provided, invalid path

- compare mode of `rasa train core` allows the whole core config comparison,
naming style of models trained for comparison is changed (this is a breaking change)

- pika keeps a single connection open, instead of open and closing on each incoming event

- `RasaChatInput` fetches the public key from the Rasa X API. The key is used to
decode the bearer token containing the conversation ID. This requires
`rasa-x>=0.20.2`.

- more specific exception message when loading custom components depending on whether component’s path or
class name is invalid or can’t be found in the global namespace

- change priorities so that the `MemoizationPolicy` has higher priority than the `MappingPolicy`

- substitute LSTM with Transformer in `EmbeddingPolicy`

- `EmbeddingPolicy` can now use `MaxHistoryTrackerFeaturizer`

hold out validation set that is excluded from training data

- defaults parameters and architectures for both `EmbeddingPolicy` and
`EmbeddingIntentClassifier` are changed (this is a breaking change)

- evaluation of NER does not include ‘no-entity’ anymore

- `--successes` for `rasa test nlu` is now boolean values. If set incorrect/successful predictions
are saved in a file.

- `--errors` is renamed to `--no-errors` and is now a boolean value. By default incorrect predictions are saved
in a file. If `--no-errors` is set predictions are not written to a file.

- Remove `label_tokenization_flag` and `label_split_symbol` from `EmbeddingIntentClassifier`. Instead move these parameters to `Tokenizers`.

- Process features of all attributes of a message, i.e. - text, intent and response inside the respective component itself. For e.g. - intent of a message is now tokenized inside the tokenizer itself.

- Deprecate `as_markdown` and `as_json` in favour of `nlu_as_markdown` and `nlu_as_json` respectively.

- for interactive learning only include manually annotated and ner\_crf entities in nlu export

- made `message_id` an additional argument to `interpreter.parse`

- changed removing punctuation logic in `WhitespaceTokenizer`

- `training_processes` in the Rasa NLU data router have been renamed to `worker_processes`

- created a common utils package `rasa.utils` for nlu and core, common methods like `read_yaml` moved there

- removed `--num_threads` from run command (server will be asynchronous but
running in a single thread)

- the `_check_token()` method in `RasaChat` now authenticates against `/auth/verify` instead of `/user`

- removed `--pre_load` from run command (Rasa NLU server will just have a maximum of one model and that model will be
loaded by default)

- changed file format of a stored trained model from the Rasa NLU server to `tar.gz`

- train command uses fallback config if an invalid config is given

- test command now compares multiple models if a list of model files is provided for the argument `--model`

- Merged rasa.core and rasa.nlu server into a single server. See swagger file in `docs/_static/spec/server.yaml` for
available endpoints.

- `utter_custom_message()` method in rasa\_core\_sdk has been renamed to `utter_elements()`

- updated dependencies. as part of this, models for spacy need to be reinstalled
for 2.1 (from 2.0)

- removed possibility to execute `python -m rasa_core.train` etc. (e.g. scripts in `rasa.core` and `rasa.nlu`).
Use the CLI for rasa instead, e.g. `rasa train core`.

- removed `_sklearn_numpy_warning_fix` from the `SklearnIntentClassifier`

- removed `Dispatcher` class from core

- removed projects: the Rasa NLU server now has a maximum of one model at a time loaded.

### Bugfixes [¶](https://legacy-docs-v1.rasa.com/1.9.2/changelog/\#id321 "Permalink to this headline")

- evaluating core stories with two stage fallback gave an error, trying to handle None for a policy

- the `/evaluate` route for the Rasa NLU server now runs evaluation
in a parallel process, which prevents the currently loaded model unloading

- added missing implementation of the `keys()` function for the Redis Tracker
Store

- in interactive learning: only updates entity values if user changes annotation

- log options from the command line interface are applied (they overwrite the environment variable)

- all message arguments (kwargs in dispatcher.utter methods, as well as template args) are now sent through to output channels

- utterance templates defined in actions are checked for existence upon training a new agent, and a warning
is thrown before training if one is missing
