Sept 2013 News

We are proud to list here some of the many new features that have been added to our products in the past year. We have worked on many of the various user interfaces to make them more user- friendly and to utilize more appropriate default settings. There has also been a strong focus on improved error handling and more extensive data import capabilities.
