Skewness and kurtosis were added. The log of changes and revisions was removed from the .pm file. Some documentation was added, clarifying the 0th percentile return value, as it returns undef() to represent -inf. A script was added to tag a release using Subversion.
This release added a workaround to a case where the variance resulted in a small negative number due to rounding errors. A LICENSE section was added to the documentation along with an examples directory with a sample script.
