19 * The type classes Mean and Variance are split in two. This is
20 required for distributions which do not have finite variance or
21 mean.

23 * The S.Sample.KernelDensity module has been renamed, and
24 completely rewritten to be much more robust. The older module
25 oversmoothed multi-modal data. (The older module is still
26 available under the name S.Sample.KernelDensity.Simple).

50 * Integer overlow in mannWhitneyUCriticalValue is fixed. It
51 produced incorrect critical values for moderately large
52 samples. Something around 20 for 32-bit machines and 40 for 64-bit
53 ones.
