I've posted a story on www.scribus.net with the link and some observations on some not so obvious features.
Its way faster than 5 and what I find interesting is the layer, commenting tools and review tools which were previous to V.7 were only available in the corporate approval product. It tells me Adobe are more serious than just basic viewing of PDF. The comment tools are quite extensive and work just like the Win32/OSX versions. Unlike 5.0.x everything works.. Even mutt is an option for mail client. Aside for the hefty download, it is IMO a no brainer to upgrade.... I am re-writing the docs to reflect all the new features and some defaults which should be changed for optimal use with Scribus. The rpm install was properly behaved and even has a proper freedesktop.org desktop file. Cheers, Peter
