Download Caliber 6.2.1

Version 6.2.0 of Caliber has been released and due to a bug a successor has already 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 second update:

New feature

• Full text search: Ignore soft hyphens when extracting searchable text from books. Note that you will have to re-index your library to take advantage of this.
• Content server: Have the Read button open PDF files in the browsers built-in PDF viewer rather than the caliber viewer since the caliber viewer is not well suited to PDF.
• Kobo driver: Add support for new firmware.
• Create icon theme dialog: Add a checkbox to install the newly created theme into caliber.
• Allow re-indexing a book for FTS by right clicking the Book details panel.
