Rasa

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

- [\6044](https://github.com/rasahq/rasa/issues/6044): Do not deepcopy slots when instantiating trackers. This leads to a significant
speedup when training on domains with a large number of slots.
- [\6226](https://github.com/rasahq/rasa/issues/6226): Added more debugging logs to the lock-stores to simplify debugging in case of
connection problems.

Added a new parameter `socket_timeout` to the `RedisLockStore`. If Redis doesn't
answer within `socket_timeout` seconds to requests from Rasa Open Source, an error
is raised. This avoids seemingly infinitely blocking connections and exposes connection
problems early.

Bugfixes
========

- [\5182](https://github.com/rasahq/rasa/issues/5182): Fixed a bug where domain fields such as `store_entities_as_slots` were overridden
with defaults and therefore ignored.
- [\6191](https://github.com/rasahq/rasa/issues/6191): If two entities are separated by a comma (or any other symbol), extract them as two separate entities.
- [\6340](https://github.com/rasahq/rasa/issues/6340): If two entities are separated by a single space and uses BILOU tagging,
extract them as two separate entities based on their BILOU tags.

Bugfixes
========

- [\6280](https://github.com/rasahq/rasa/issues/6280): Fixed `TypeError: expected string or bytes-like object`
issue caused by integer, boolean, and null values in templates.

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

- [\6255](https://github.com/rasahq/rasa/issues/6255): Rasa Open Source will no longer add `responses` to the `actions` section of the
domain when persisting the domain as a file. This addresses related problems in Rasa X
when Integrated Version Control introduced big diffs due to the added utterances
in the `actions` section.

Bugfixes
========

- [\6160](https://github.com/rasahq/rasa/issues/6160): Consider entity roles/groups during interactive learning.

Bugfixes
========

- [\6075](https://github.com/rasahq/rasa/issues/6075): Add 'Access-Control-Expose-Headers' for 'filename' header
- [\6137](https://github.com/rasahq/rasa/issues/6137): Fixed a bug where an invalid language variable prevents rasa from finding training examples when importing Dialogflow data.

Features
========

- [\6150](https://github.com/rasahq/rasa/issues/6150): Add `not_supported_language_list` to component to be able to define languages that a component can NOT handle.

`WhitespaceTokenizer` is not able to process languages which are not separated by whitespace. `WhitespaceTokenizer`
will throw an error if it is used with Chinese, Japanese, and Thai.

Bugfixes
========

- [\6150](https://github.com/rasahq/rasa/issues/6150): `WhitespaceTokenizer` only removes emoji if complete token matches emoji regex.

Bugfixes
========

- [\6143](https://github.com/rasahq/rasa/issues/6143): Prevent `WhitespaceTokenizer` from outputting empty list of tokens.
