Jumsoft has launched a Relationship 2.0, a major upgrade to its contact management utility for the Mac. The program provides tools for manually or automatically arranging contacts into assigned groups, and offers password protection options. The new version delivers a wide range of enhancements such as full e-mail integration, and a re-designed event feature with iCal sync support. With the new e-mail functionality users can now link e-mails to specific contacts or projects within the app.
