Download Caliber 6.18.1

Version 6.18 of Caliber has been released. This open source e-book management tool is available for Windows, Linux, and macOS. It can, among other things, look up all relevant information and cover images, and convert e-books to make them suitable for various types of e-readers. Furthermore, the program can convert newspapers, magazines and news articles into e-book format based on RSS feeds. Books can also be purchased with Caliber from well-known online stores.

In version 6.0 the switch to Qt 6 has been made, among other things. However, this does mean that the program only works on computers equipped with a 64bit processor and requires at least Windows 10 or macOS 11. Furthermore, you can now 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 update:

New features

• Cover download: Allowing saving alternate covers to disk or in the book’s data folder by right clicking on the cover. Closes tickets: 2020603.
• Content server: Allow disabling full text search via the web interface. Closes tickets: 2020237.
• When sending books to the device confirm the overwrite if the book already exists on the device. Closes tickets: 2020233.
• E-book viewer: Handle horizontal wheel events as section jumps in paged mode.
• Comic Input: When grayscaling comic images use 16bit gray instead of 8bit for better fidelity. When using the PNG format for images these results in larger files but with better grayscaling fidelity.
• Add a new option in Preferences->Searching to disable keyboard searching in book list (ie you can turn off the behavior that pressing a key will jump to the first book whose title starts with that letter).
• Manage categories dialog: Use alternating row colors and allow adjusting row height. Closes tickets: 2018423.
• Allow assigning a keyboard shortcut in Preferences->Shortcuts to open the data folder of a book.
• Various improvements to syntax highlighting for the Markdown long text editor.
