Calibre 6.12.0

calibre

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
