Software update: Caliber 2.83

After a somewhat longer than usual interval due to the travel of lead developer Kovid Goyal, version 2.83 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

• PDF Output: Default to generating PDFs with a page size of letter instead of taking the page size from the output profile.
  This avoids user confusion/bug reports about PDF Output having “too large fonts”. There is a new option “Use profile size” to have the conversion use the output profile page size instead.
• PDF/DOCX Output: Add separate, pdf/docx specific, page margin settings that override the common settings.
  Useful because page margin settings for page oriented formats, such as PDF and DOCX are usually different than those for reflowable formats such as EPUB
• Table of Contents tool: Add an undo button
• Metadata jacket: Show custom rating columns using stars
• Metadata jacket: Change formatting of series to match that used by the book details panel. Also allow access to the raw series name and number when customizing the jacket template.
• calibredb check_library: Vacuum database when running the check
• Check Book: Add a check for empty identifier elements
