Umbraco 7.7: User Management
Umbraco CMS version 7.7 brought dramatic changes with user management. The new interface is more visual, and allows group management. You can also toggle back and forth between list and tile views of your users.
Umbraco: Release 7.8
Umbraco version 7.8 introduced back office tours, making it easier than ever to highlight the features of the CMS. You can even create custom tours to show off your work. This version also replaced the old Properties tab with a much cleaner Info tab.
