v4.0 [Nov 18, 2011]
-New data type: lunar
-Data are entered as dates but are treated as circular data based on the lunar month. This is useful when studying phenomena that might be related to lunar phase (e.g. turtles laying eggs during the full moon).
-Analyzing frequency data
-Data can now be entered directly into the data editor as a frequency table, with one variable being the circular data and an associated Linear variable giving the frequency (number of observations for that circular measurement). These can then be used to produce histograms and basic stats.
