@moro The interface you’re looking for is the Reference App, a general purpose OpenMRS Distribution. You can find out more about the latest release and its relation to the legacy UI here: Reference Application Implementation Documentation
Legacy OpenMRS vs. Reference Application The Reference Application is built on top of the OpenMRS Platform 2.x, which still includes the Legacy User Interface (the original web application). You can still download and use the legacy application. The Reference Application is a set of modules that are installed in addition to the legacy OpenMRS web application. It means that when you install the Reference Application, you can still access all the features of the legacy application, however we keep them hidden from users by default.
It’s not clear how you installed OpenMRS, but if you’re doing this via the downloads page, you’d want to choose one of the Reference App options from there.
