Download Caliber 6.6.1

Version 6.6.0 of Caliber has been released. This open source ebook manager is available for Windows, Linux and macOS. Among other things, it can look up all relevant information and cover images, and convert e-books to make them suitable for the various types of e-readers. Furthermore, the program can convert newspapers, magazines and news articles based on RSS feeds into e-book format. Books can also be purchased with Caliber from the well-known webshops.

In version 6.0 among other things, the switch to Qt 6 has been made. However, this means that the program only works on computers equipped with a 64-bit processor and a minimum of Windows 10 or macOS 11 is required. Furthermore, it is now possible to search all books in the library instead of just the current book, and there are also versions for Arm and Apple Silicon processors. The following changes and improvements have also been made in this fourth update:

New feature

• Book details: allow displaying multi-valued categories such as tags on separate lines via Preferences->Look & feel->Book details.
• Tag browser: When searching the Tag browser also allow filtering the book list to show only books that match one of the categories currently shown in the Tag browser. Close tickets: 1989813.
  To use, enable these two preferences: “Preferences->Look & feel->Tag browser->Hide empty categories” and “Find shows all items that match”. Then, when searching the Tag browser, press Ctrl+Alt+Shift+F to restrict the displayed books.
