Rasa

Bugfixes
========

- [\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.
-

[\5506](https://github.com/rasahq/rasa/issues/5506): Set default value for `weight_sparsity` in `ResponseSelector` to `0`.

: This fixes a bug in the default behaviour of `ResponseSelector` which was accidentally introduced in `rasa==1.8.0`.
Users should update to this version or `rasa>=1.9.3` and re-train their models if `ResponseSelector` was used in their pipeline.

Improved Documentation

- [\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.

weren't the same as in 1.7.x. Fixed by setting weight sparsity to 0.

Improved Documentation
======================

- [\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
deploying-your-rasa-assistant\_custom-dependencies.
