Objectpark Software has released Letter Star Pro 1.6 and Letter Star 1.6, new versions of its applications for writing “quality letters with ease and style.” Letter Star was formerly known as LetterWorks, but due to legal reasons the application had to be renamed to Letter Star. The free updates feature several usability improvements and stability enhancements. Letter Star sells for US$29.95 and Letter Star Pro costs $59.95. Both require Mac OS X 10.2.3 or later.
