Software update: Caliber 2.84

Version 2.84 of Caliber has been released. Caliber is an open source and cross platform ebook management program. 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. The following changes and improvements have been made in this release:

New Features

  • Kindle driver: Also delete book thumbnails from the system directory when deleting books.
  • Conversion: Use the same regular expression engine as is used by the Edit Book tool. The new engine has much better support for Unicode characters/character classes.
  • Edit Book: Add keyboard shortcuts to jump to opening and closing tags (Ctrl+{ and Ctrl+})
  • Add API to pre-process image data in recipes easily
  • fetch-ebook-metadata: add option to use only a single metadata plugin

Bug Fixes

  • E-book viewer: Fix a regression in the previous release that broke printing from inside the viewer.

  • AZW3: Preserve the primary-writing-mode EXTH header field when round-tripping AZW3 files. Should fix editing/conversion of RTL AZW3 files causing page turning to become left-to-right on the Kindle
  • AZW3 Output: Set the primary-writing-mode EXTH header when the input document has page-progression-direction set to RTL as this is apparently required on newer Kindle firmware for right-to-left page turning
  • Fix a misbehaving wireless device connection can cause caliber to hang when opening the Connect/Share menu. Close tickets: 1676522
