Calibre is an eBook management software that is almost without equal, on any platform that runs it. A few years ago nobody could anticipate that eBooks will take our lives completely, but the rise of eBook readers and the fact that most books are cheaper in digital form, proves that it was inevitable for someone to take matters in his own hands and develop something that can actually manage an entire library.

Major part of this release: "A 'Live CSS' tool that shows all the style rules for the tag you are currently editing. You can use it to easily jump to any style rules that affect the current tag. Enable it via View->Live CSS,"
Calibre is a very rapidly evolving piece of software, with weekly releases. As a results bugs are inevitable. Calibre team rely on calibre's users to report bugs, so that they can be fixed as quickly as possible. To report bugs use the calibre bug tracker.
