Calibre 2.70 comes two weeks after the release of Calibre 2.69, and it promises two new features. First, it’s a tool implemented in the Edit Book component and designed to let users download external resources, such as stylesheets or images, that aren’t included in a book. The second feature added in the Calibre 2.70 release is support for custom columns in the Manage Categories sub menu of the Alter Tag Browser function. Also new is the implementation of the Various Danish news source, which has been submitted by Allan Simonsen.
