In this new version of the application, a transition from the Qt WebKit engine to the Qt WebEngine has been made, although it has created some issues with backward compatibility.
Content-server in Calibre 4.0 has received several new features. Users can now edit metadata, convert books to other formats, as well as add and remove books and formats.
One of the major changes in this update is the new e-book viewer. In previous versions of the program, the text was surrounded by toolbars. Now, the toolbars have been removed, and options are accessible with a right-click.
