The Caliber open source project is the official e-book management tool of Caliber. It can view, convert, edit and categorize eBooks in all major formats. Caliber is cross-platform software that runs on Linux, Windows and macOS.
Caliber 6.15 is officially released, the updates are as follows:
new function
- Allows adding external links to tags, series, publishers, etc. in addition to authors
- calibre:// URL scheme: Added support for a new URL type that pops up in a new window specifying the book's metadata
- EPUB output: Images are not shrunk to fit screen size by default, as modern readers do a good enough job themselves that this can be controlled via an option in the EPUB output section of the conversion dialog.
- Edit metadata dialog: Add button to easily pop up category edit window
- Metadata Download: Allow specifying rules to convert publisher names in addition to author and tag names
- Edit metadata dialog: Use colored borders and icons to show errors in line editing
- A new tweak in Preferences->Tweaks to control what runs when clicking a URL in caliber.
