Something that I would like to see in a future version of Calibre (or a fork) is news-download recipes changed to a plugin system that can be updated separately of Calibre itself. It is not ideal that if a news recipe becomes obsolete due to changes on the respective news website, one has to upgrade Calibre to a new version. For users whose distros package only a certain version of Calibre, it would be nice to continue running that distro-supported version but simply be able to update the news recipes from within the Calibre settings.
