Calibre 2.66 comes just one week after the release of the previous maintenance update, Calibre 2.65.1, and promises to update the application’s logo to a more simplified version, upgrade the driver for Kobo e-book readers to firmware 3.20, and add support for the fairly new PocketBook Touch HD reader. Another interesting feature introduced in Calibre 2.66 is the ability to restrict the search functionality of the Edit Book component to only the files that have been opened for editing. Last but not least, the new Calibre maintenance release introduces a new news source, namely Contropiano.
