On September 8, 2016, Calibre developer Kovid Goyal announced the release of a new maintenance update for his popular, free, open-source and cross-platform ebook library management software.

Calibre 2.67 is now the most stable and advanced version of the application, and among the new features it includes, we can mention an updated Kobo driver that supports Kobo Aura One e-book reader's firmware version 4, support for reading more image formats as covers, and support for displaying book counts on the Tag Browser's right edge.

Moreover, there's the ability to create custom rating columns that support half-stars, a new option in the Tag Browser component to allow you to turn off the display of counts mentioned above, and Open Publication Distribution System (OPDS) feeds improvements to the content server.

"Change the value of for entries in the acquisition feed to be the last modified date for the book. Also make the size and last modified timestamp available as attributes in the acquisition links. Useful for integration with third party applications," reads the release notes.

New tool lets you sort rules in a CSS stylesheet

Continuing, Calibre 2.67 introduces a new tool in the Edit Book component to let you sort rules in a CSS stylesheet, implements a tweak in the Tweaks section of the Preferences dialog to allow you to exclude various image types being read as covers when they're dragged and dropped into the Book Details panel.

The Cover Browser component has been updated as well to allow any metadata field to be used as a subtitle, a new option has been added to the "Remove Unused CSS" tool of the Edit Book component to let users merge CSS rules that contain identical selectors, and there are small bug fixes for DOCX Output, ODT Input, and PDF Output components.

Last but not least, the Ars Technica news source has been improved in Calibre 2.67, which you can download right now via our website for GNU/Linux, Mac OS X, and Microsoft Windows operating systems.
