I can't say that I am very happy with this update. Unfortunately, the app does not feel native to macOS at all.
The issues that I noticed right away are:
the lack of a proper MacOS toolbar
the uwp-like, blue titlebar at the top
the design of the checkboxes, switches and buttons makes the app look like it's written in Java
The main components of the app (sidebar, listview and detail) actually look fairly convincing. Maybe there is a chance, that adjusting the details I mentioned above, will hide the fact that the app wasn't primarily written for macOS.
But for now, I will switch to another password manager.
