"Frontiers in RF design tools and flows for 2006 and beyond

XXX's 2006 software release cycle represents an active year, advancing design and modeling integration along several fronts, including EM, RF, and System design and expanding our capabilities in the high-speed digital signal integrity domain. This overview gives a high level view of "What's New" in both the products and the directions of the world's leading provider of RF design tools, and helps to place the technology and design techniques covered during the rest of the seminar in their proper context."

The word appears in the title of the above paragraph and nowhere else. Could it mean something like "trend"??
