  • added method to tracker to retrieve the latest entities #68

[0.7.3] - 2017-10-31

Fixed

  • fixed documentation of story visualization

[0.7.2] - 2017-10-30

Added

  • added facebook bot example
  • added support for conditional checkpoints. a checkpoint can be restricted to only allow one to use it if certain slots are set. see docs for details
  • utterance templates in domain yaml support buttons and images
  • validate domain yaml and raise exception on invalid file
  • run script to load models and handle messages from an input channel

Changed

  • small dropout in standard keras model to decrease reliance on exact intents
  • a LOT of documentation improvements

Fixed

  • fixed http error if action listen is not confirmed. #42

[0.7.1] - 2017-10-06

Fixed

  • issues with restart events. They created wrong a messed up history leading to wrong predictions

[0.7.0] - 2017-10-04

Added

  • support for Rasa Core usage as a server with remote action execution

Changed

  • switched to max code line length 80
  • removed action id - use action.name() instead. if an action implementation overrides the name, it should include the action_ prefix (as it is not automatically added anymore)
  • renamed rasa_dm.util to rasa_dm.utils
  • renamed the whole package to rasa_core (so rasa_dm is gone!)
  • renamed Reminder attribute id to name
  • a lot of documentation improvements. docs are now at https://core.rasa.ai
  • use hashing when writing memorized turns into persistence - requires retraining of all models that are trained with a version prior to this
  • changed agent.handle_message(...) interface for easier usage

[0.6.0] - 2017-08-27

Added

  • support for multiple policies (e.g. one memoization and a Keras policy at the same time)
  • loading domains from yaml files instead of defining them with python code
  • added an api layer (called Agent) for you to use for 95% of the things you want to do (training, persistence, loading models)
  • support for reminders

Changed

  • large refactoring of code base

[0.5.0] - 2017-06-18

Added

  • ScoringPolicy added to policy implementations (less strict than standard default policy)
  • RasaNLUInterpreter to run a nlu instance within dm (instead of using the http interface)
  • more tests

Changed

  • UserUtterance now holds the complete parse data from nlu (e.g. to access attributes other than entities or intent)
  • Turn has a reference to a UserUtterance instead of directly storing intent & entities (allows access to other data)
  • Simplified interface of output channels
  • order of actions in the DefaultPolicy in possible_actions (ActionListen now always has index 0)

Fixed

  • RedisTrackerStore checks if tracker is stored before accessing it (otherwise a None access exception is thrown)
  • RegexInterpreter checks if the regex actually matches the message instead of assuming it always does
  • str implementation for all events
  • Controller can be started without an input channel (e.g. messages need to be fed into the queue manually)

[0.2.0] - 2017-05-18

First released version.
