Version 2, released April 2005

• New method: Fuzzy Discriminant Analysis. We have added Fuzzy Discriminant Analysis to the list of methods available.
• Unlimited data set size: Data set size is now limited only by your computer's power and memory - even for highly complex calculations. Most reasonably fast computers should handle a 1000 x 1000 data set easily.
• Improved graphics: Plotting and export of graphs has been improved; new type of plots added to certain analyses.
• Different ordination method: We have changed the method used for ordination in Fuzzy C-means from MDS to DECORANA. This increases the speed and accuracy of the ordination.
• Faster calculation: The speed at which Fuzzy performs many calculations has been dramatically increased, thanks to new data array handling technology.
• Help system and manual: Fuzzy's Help system has been much improved, and the full instruction manual has also been completely revised.
