This release does not add any application feature or bugfix, instead it simplifies the docker image. Starting with 2.1.8 version, papermerge/papermerge docker image includes static assets, (UI) and websockets server; this basically hides from docker image users such details as separation of frontend from the backend.
For more details on how to use new docker image see:
