Rasa

_Pre-release version_

Bugfixes
- [12099](https://github.com/rasahq/rasa/issues/12099): Fix validation metrics calculation when batch_size is dynamic.
- [12102](https://github.com/rasahq/rasa/issues/12102): Fixes the bug when a slot (with `from_intent` mapping which contains no input for `intent` parameter) will no longer fill for any intent that is not under the `not_intent` parameter.

- [11087](https://github.com/rasahq/rasa/issues/11087): Add metadata to Websocket channel. Messages can now include a `metadata` object which will be included as metadata to Rasa. The metadata can be supplied on a user configurable key with the `metadata_key` setting in the `socketio` section of the `credentials.yml`.

Improvements
- [11995](https://github.com/rasahq/rasa/issues/11995): Add capability to send compressed body in HTTP request to action server.
Use COMPRESS_ACTION_SERVER_REQUEST=True to turn the feature on.

Bugfixes
- [11926](https://github.com/rasahq/rasa/issues/11926): Decision to publish docs should not consider next major and minor alpha release versions.

- [11596](https://github.com/rasahq/rasa/issues/11596): Caching `Message` and `Features` fingerprints unless they are altered, saving up to 2/3 of fingerprinting time in our tests.

Bugfixes
- [11829](https://github.com/rasahq/rasa/issues/11829): Implements a new CLI option `--jwt-private-key` required to have complete support for asymmetric algorithms as specified
originally in the docs.

- [11588](https://github.com/rasahq/rasa/issues/11588): Fixes scenarios in which a slot with `from_trigger_intent` mapping that specifies an `active_loop` condition was being filled despite that `active_loop` not being activated.
In addition, fixes scenario in which a slot with `from_trigger_intent` mapping without a specified `active_loop` mapping condition is only filled if the form gets activated.
Removes unnecessary validation warning that a slot with `from_trigger_intent` and a mapping condition should be included in the form's required_slots.
- [ato-161](https://github.com/rasahq/rasa/issues/ato-161): Fixed a bug where `DIETClassier` crashed during training
when both masked language modelling and evaluation
during training were used.

Improved Documentation
- [11571](https://github.com/rasahq/rasa/issues/11571): Rasa SDK documentation lives now in Rasa Open Source documentation under the _Rasa SDK_ category.

- [11540](https://github.com/rasahq/rasa/issues/11540): Fix bug where `KeywordIntentClassifier` overrides preceding intent classifiers' predictions
although the `KeyWordIntentClassifier` was not matching any keywords.
