+## Unreleased

+### Breaking changes
+ - internal dependencies are now listed as regular dependencies in the `setup.py` file to overcome issues and make the installation process less complicated. This implies you need to install packages according to their dependencies and can no longer use the `external` tag as in `pip install airo-typing[external]`.
+ see [issue #91](https://github.com/airo-ugent/airo-mono/issues/91) and
+ [PR](https://github.com/airo-ugent/airo-mono/pull/108) for more details.
