What’s New

Version 2.81.0:

  • Amazon metadata download: Allow downloading amazon metadata from multiple sources. You can now configure the Amazon plugin via Preferences->Metadata download to use either the amazon servers, or various search engine caches to get the metadata. Should help with the recent CAPTCHA problems when downloading metadata from amazon
  • Kobo driver: Add support for new firmware
  • Edit Book: Spell Check dialog: Always add the original word as one of the spelling corrections, so that small edits to the word can be made easily.
  • Edit Book: Saved searched Dialog: Allow re-arranging the saved searches using drag and drop.
  • Implement auto update of built-in metadata download plugins, just as for recipes and Get Books plugins. Needed as the websites they get data from often change.
  • Edit Book: When inserting full screen images, use the actual image dimensions in the generated SVG code, when available
  • Linux installer: Check that the umask is suitable before running the installer. Should fix breakage on systems where users have changed the user umask but neglected to also alter it for sudo
  • Bulk metadata edit: Remove the control to delete specific formats as it is redundant. This functionality is already present by right clicking the Remove books button
  • TXT Input: When detecting the encoding of txt files only use the first four kilobytes of text. Fixes excessively slow conversion of very large text files.
  • Get Books: Fix price not being displayed for books from Amazon dues to website changes
  • GetBooks: Update Google Books plugin for website changes
  • E-book viewer: Fix slow startup when recently opened files are on a slow/malfunctioning networked filesystem.
  • Google metadata download: Fix metadata not being found when the title of the book includes a sub-title
  • Improve downloading of covers from the google books metadata source
  • News download: Fix a bug that could cause a crash when downloading an SVG image.
  • Edit book: Fix a regression that caused pasting copied text from programs that generate both HTML and plain text when copying to paste the HTML in preference to the plain text
