Calibre 6.12.0

Calibre is an open source e-book library management application that enables you to manage your e-book collection, convert e-books between different formats, synchronize with popular e-book reader devices, and read your e-books with the included viewer.

It acts as an e-library and also allows for format conversion, news feeds to e-book conversion, as well as e-book reader sync features and an integrated e-book viewer.

Calibre’s features include: library management; format conversion (all major ebook formats); syncing to e-book reader devices; fetching news from the Web and converting it into ebook form; viewing many different e-book formats, giving you access to your book collection over the internet using just a browser.

Calibre 6.12.0 new features:

  • E-book viewer: Read aloud: On Windows switch to using the new Microsoft speech subsystem with access to more voices
  • Note that this means that old voice, speed and audio devices setting will not be used so a reconfiguration might be needed.
  • calibre:// URL scheme: allow specifying a Virtual library for show_book URLs
  • Add by ISBN: Allow adding using identifiers other than ISBN as well
  • Update bundled Qt to 6.4 this means calibre on macOS is now only supported on Big Sur and newer
  • Spell check dialog: Allow up and down arrow keys to work regardless of focus
  • Allow multiple Template tester dialogs

Bug fixes

  • Windows MTP device driver: Ignore failure to enumerate objects inside non-root folders
  • There are apparently a lot of devices out there that fail in this way. So rather than aborting the scan simply ignore the folder.
  • Book list: Fix a regression in the previous release that broke dragging to select multiple books
  • Content server viewer: Fix reload book not actually reloading until the browser is also refreshed
  • E-book viewer: Fix occasional false warning about highlight being overwritten
  • E-book viewer: Fix detection of selected highlights when all text is selected
  • Fix an error when embedding metadata into a large number of books
  • When updating metadata in EPUB 2 files and no language is specified, do not remove the tag as this causes epubcheck to complain. Instead set the language to “und”
  • Wireless device driver: Remove the timeout for initial connection
  • Use an icon rather than a color to report errors in fields and the search box
  • Conversion dialog: Regex builder: Workaround bug in Qt that prevented searching for non breaking spaces in the wizard used to test search expressions
  • Spell check dialog: move down after correcting word, not up
  • Get books: Fix Mobileread store plugin not working
