Previously, new users were greeted by an onboarding screen that only gave some hints how to get started. Now they are guided through all basic settings that are required for usage or popular and difficult to find.
The setup wizard looks different depending on the available features.
At the end you have the option to create sample groups and tags and a page (unpublished) that contains some shortcodes. I hope that the wizard will help users to get started and to understand the various features without having to climb through settings and to study the documentation.
