Debian scribus-ng package goes 1.3.5svn
Debian/Ubuntu scribus-ng package (where "ng" stands tongue-in-cheek for new generation) has been tracking 1.3.4 Scribus tree for a long time. Recently, 1.3.4 was completely retired as undeveloped and unmaintained branch, so scribus-ng was moved over to track 1.3.5svn (subversion trunk) code. All users of our Debian/Ubuntu packages from the Scribus Archive are strongly encouraged to upgrade. Remember that 1.3.5svn can read 1.3.4 files, but 1.3.3.x stable Scribus can not read newer file versions, so make sure you structure your workflow accordingly.
