Calibre (64-bit) specifications

What's new in version 2.0

New Features

  • For a summary of the major changes in calibre between 1.0 and 2.0, see
  • Add support for MTP devices (Android phones/tablets) on OS X
  • Update the version of Qt used by calibre to Qt 5. This fixes various longstanding bugs in calibre that were caused by bugs in Qt 4.
  • Edit Book: Make the edit saved search/add saved search popup window non-modal.
  • Tag Browser: Show format specific icons for the format entries in the Tag Browser
  • Library check: Add buttons to conveniently mark all fixable/deletable items.

Bug Fixes

  • E-book viewer: Reloading the book now re-opens it at the current position even if the option to remember position when quitting is turned off
  • E-book viewer: Remove extra spacing between document and scrollbars. This is particularly noticeable when using a dark theme for the viewer.
  • PDF Output: Fix balanced parentheses in the text of items in the Table of Contents not being rendered properly by some PDF viewers.
  • Edit book: Abort terminal save on save error instead of quitting editor
  • Get Books: Update the Project Gutenberg plugin for website changes
  • Plugin loading: When multiple plugin classes are present in the namespace, use the one with the qualified name that has the least components
  • Edit Book: Prevent long saved searches from making the saved search dialog too wide
  • Comic Input: Sort pages placed in sub-folders correctly (as long as all pages have the same number of parent folders).
  • Conversion: Fix the word @page in a comment inside a stylesheet with no following {} causing the rest of the stylesheet to be ignored.
  • Fix comparing AZW3 to ORIGINAL_AZW3 from the book details panel not working
