Version 6.21 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
- DOCX Output: Add support for SVG images. Now the generated DOCX will contain both the rasterized version of the SVG image and the original SVG image as the preferred source, which is supported by modern versions of Word.
- E-book viewer: Allow configuring the actions triggered by touch gestures. Closes tickets: 2023367.
- DOCX Input: Add support for SVG images.
Bug fixes
- Windows: Fix a regression in the previous release that could cause files to be deleted if one of the files/folders was open in another program while changing title/author in caliber.
- macOS: Fix extra dock icons visible when doing a job using Qt WebEngine such as converting to PDF or searching in Get books. Closes tickets: 2023395.
- macOS and Linux: Fix an error when changing metadata or deleting books whose files are owned by another user. Closes tickets: 2023476.
