Download Caliber 3.23

A new version of Caliber has been released. Caliber is an open source e-book management program and 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 at the well-known web stores. The program is under active development and a new version is usually released every other week on Friday. In version 3.23, the following improvements have been made:

New features

• Kobo driver: Add support for new firmware. Close tickets: 1767589
• Book polishing: Add an option to upgrade EPUB 2 to EPUB 3
• DOCX Input: Convert text written with dingbat fonts such as Wingding or Symbol correctly.
• When choosing the page to use as a cover from a PDF file, add a button to render more pages, if needed
• TXT Input: Add support for embedded images that use relative URLs when converting markdown or textile. Note that this will only work if you are converting using the ebook-convert command line tool as the main caliber program moves files around, so relative references will not be valid.
• Edit book: Insert special character: Add an option to select if searching should match all words or any of the words
• Edit book: Insert special character: When searching by name match prefixes in addition to whole words. So you can now type “horiz” to match “horizontal”.
• Linux installer: Simplify the command used to install caliber and add support for Ubuntu 18.04 which is missing a default python executable
• When upgrading EPUB 2 to EPUB 3 add the ‘epub’ namespace to all HTML files, for convenience. Close tickets: 1765944
