 The main navigation menu has been reorganised, placing site configuration options in a 'Settings' submenu. This includes two new items, which were previously only available through the Django admin backend: 'Groups', for setting up user groups with a specific set of permissions, and 'Sites', for managing the list of sites served by this Wagtail instance.

 The Wagtail userbar (which gives editors quick access to the admin from the site frontend) has been redesigned, and no longer depends on an iframe. The new design allows more flexibility in label text, more configurable positioning to avoid overlapping with site navigation, and adds a new "Show in Explorer" option. This feature was developed by Thomas Winter and Gareth Price.
