Scribus

Scribus is an Open-Source program that brings award-winning professional page layout to Linux/Unix, OS X, and Windows desktops with a combination of "press-ready" output and new approaches to page layout. Underneath the modern and user-friendly interface, Scribus supports professional publishing features such as CMYK color, separations, ICC color management, and versatile PDF creation. Scribus/Aqua is a port of Scribus to a native Aqua build using Qt Free for OS X.

• Color precision for fill colors has been expanded to 64 bit floating point.
• Scribus can now handle color palettes in the new ISO standard CxF3 (See: https://www.xrite.com/de/page/cxf-color-exchange-format). CxF3 files cannot only store palettes in different color models (e.g., RGB, CMYK, LAB) and output intents, but also allow for storing spectral colors, which enables even greater colour precision. Scribus is the first DTP software that supports this demanding standard.
• Existing import filters have been upgraded to support the LAB color model (where applicable).
• The Barcode plug-in has been updated and offers new features.
• Many bugs regarding fringe uses have been fixed in the PDF library, both for print PDFs and PDF forms.
• Several new commands have been added to the scripting engine, so as to make the document creation via scripts easier and more versatile.
• Thanks to the work of the Document Liberation Project and particularly David Tardon, experimental import filters for ZonerDraw vector drawings (versions 4 and 5) and QuarkXPress documents (versions 3 and 4) have been added.
• Many potential stability and security issues revealed by Coverity scans have been fixed.
• The complete changelog for 1.5.4 is available here.
