Rasa-sdk

Bugfixes
========

- [\110](https://github.com/rasahq/rasa/issues/110): Exit program (`python -m rasa_sdk --actions actions` or
`rasa run actions --actions actions`) if a requested module under the
`--actions` command-line option cannot be found.

Bugfixes
========

- [\153](https://github.com/rasahq/rasa/issues/153): Make it possible to use the `requests` library inside the default Rasa SDK container.

Improvements
============

-

[\130](https://github.com/rasahq/rasa/issues/130): Copied over instance methods `last_executed_action_has()`, `get_last_event_for()` and

: `applied_events` from the Rasa `DialogueStateTracker` class to the SDK `Tracker` class.

- [\145](https://github.com/rasahq/rasa/issues/145): Add `poetry` for dependency management and reduce the size of Docker image.

Miscellaneous internal changes
==============================

- \148, \149

Changed
=======

- `ReminderScheduled` and `ReminderCancelled` now take `intent` and `entities`
as options, instead of `action`. This is because starting with Rasa 1.7 reminders
trigger intents (with entities) instead of actions.
- The following `FormAction` methods are now `async` by default: `validate_slots`,
`validate`, `submit` and `run`. User-defined classes inheriting from
`FormAction` should be adapted to use `async` for these methods. Existing
synchronous implementations will continue to work as normal, but this behaviour will
be deprecated in the future.
- The following `ActionQueryKnowledgeBase` methods are now `async`:
`utter_objects` and `run`.
- The following `KnowledgeBase` methods are now `async`:
`get_attributes_of_object`, `get_key_attribute_of_object`,
`get_representation_function_of_object`, `get_objects` and `get_object`. Same
warning for `FormAction` applies here - user-defined classes should be updated to
use `async`, but will continue to work for the moment.
- The following `InMemoryKnowledgeBase` methods are now `async`:
`get_attributes_of_object`, `get_objects` and `get_object`.
