v1.5

This marks the implementation of improved Warden rules validation with Pydantic and a major refactoring of the Warden automodule.
It is also supposed to be the last release before I properly version new features / bugfixes, with a detailed changelog for each new release.
In case I end up not following through, feel free to screenshot this and rub it in my face on a daily basis 😃

No detailed changelog available: this release was tagged at a later time in an effort to implement proper versioning.
