application release , which automates the basic operations of maintaining a collection of electronic books. Caliber allows you to navigate the library, read books, convert formats, synchronize with portable devices on which reading is carried out, view news about new products on popular web resources. The composition also includes a server implementation for organizing access to the home collection from anywhere on the Web.
The new version has moved from the Qt WebKit engine to Qt WebEngine and completely rewritten the interface for viewing electronic books, which is now focused on content and does not contain elements that distract the user (all control buttons are hidden by default and are displayed only when necessary). The standalone viewer code is built on a common code base with an interface for viewing in a browser. To the content access server (), which allows you to remotely view your personal collection and read the books present in it from a smartphone, tablet or any device with a browser, the functions of editing metadata, adding / deleting books and converting books from one format to another have been added.
