Yes! We recently rebuilt the UI from scratch and as part of that we
also changed how it is integrated into Routinator. Last week we merged
that PR (https://github.com/NLnetLabs/routinator/pull/952).

The UI’s assets are now included in the regular Routinator repository
and routinator-ui will be deprecated.

I have a few smaller items left that I want to include in the 0.14.0
release, but I hope to get the the RC out very soon.
