Caliber 4.0

If you are a compulsive book reader, this news interests you. Although, on the other hand, it is also possible that you already know it, because Kavid Goyal announced on Friday the launch and availability of Caliber 4.0, the first major update in two years for this e-book management software. As a major release, the new version of Caliber includes interesting news, some of them related to what we can see thanks to a rewrite.

What has been completely rewritten in Caliber 4.0 is its ebook viewer. The new version focuses on displaying the text of the book avoiding distractions. On the other hand, they have also included new features in the content metadata editor, because anyone who likes to store books, like those of us who like music, like their metadata to provide the information correctly.

Other new features included in Caliber 4.0

  • Ability to add or remove books from the content server.
  • Possibility of converting books from / to the formats supported by Caliber.
  • The content server is now a complete interface to our libraries.
  • The new e-book viewer shares a codebase with the browser viewer, allowing its developer to add support for new features such as annotations.
  • It now uses the Qt WebEngine web content rendering engine, which adds Chromium capabilities.
  • Support for HTML and CSS has been reduced.

Caliber 4.0 is now available for download from its official page for Windows and macOS. As usual, Linux users have different ways to install it, among which we have the Flatpak version or the official repositories of our Linux distribution. If we want to use the latest version, right now only the Flatpak version is good for us or download the binaries as explained in this link.
