Version Published Release Notes
1.2

This version accounts for the autocorrelation of either input series, preserving both in the random permutations, yielding the probability that any observed cross-correlation is not due to the autocorrelation of either input series.
1.1.1

Fixed bug that ignored input numvalues if provided.
1.1

Changed to use absolute value, so it detects negative correlations as well
