Download Caliber 6.15

Version 6.15 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

• Allow adding external links to tags, series, publishers, etc. in addition to authors. The links show up as click-able icons in the book details panel. They can be set by right clicking the author/tag/etc. in the Tag browser and choosing “Manage”.
• caliber:// URL scheme: Add support for a new type of URL that pops up the metadata of the specified book in a new window. Works even with books not in the current library. See this page for details.
• EPUB Output: Do not shrink images to fit the screen size by default, as modern readers do this themselves well enough. Can be controlled via an option in the EPUB Output section of the conversion dialog.
• Edit metadata dialog: Add buttons to pop up the category editing windows easily.
• Metadata download: Allow specifying rules to transform publisher names in addition to author and tag names. Closes tickets: 2012304
• Edit metadata dialog: Use both a colored border and an icon to indicate errors in line edits. Closes tickets: 2007764
• A new tweak in Preferences->Tweaks to control what program is run when clicking on URLs in caliber.
