Scribus released the new 1.4.0 version on the 01. January 2012. The 1.4 release notes have a detailed log of the tons of improvement to that great publishing software. It took around 5 years for this new version to appear. "Scribus 1.4.0 partially fixes rendering issues and simplifies use of various tools." There has been may improvements on the text handling as seen on the quoted free graphics blog post: Scribus 1.4 in a nutshell.
I want to emphasize that this new scribus can now directly compile latex code in any chosen render frame. This is extremely useful for scientific posters. (Before one had to compile into pdf and then import each into frame boxes). The shown screenshot features a momentum background distribution function.
