The release of scipy is coming along, but I think we need to postpone the release until Tuesday as I have found some bugs in special that need addressing. Comments? -Travis Oliphant

I haven't been tracking CVS for the past week, but the last time I checked, there were some errors in stats/distributions.py . Specifically, triang.stats gives the same mean regardless of the loc parameter (the others may be wrong, too); uniform.ppf(x,...) for x == 0 or 1 gives 0 or 1 respectively despite the loc and shape parameters, and x in between give the right values. These bugs may or may not generalize to other distributions. Prioritize as you see fit. :-)

Thanks Robert. The first bug was probably due to the incorrect formula for the mean of the triangular distribution. That has been fixed (it should change with different loc and scale parameters). The second ppf bug affected all distributions (it was in the base class). Thanks for finding it. It has been corrected. -Travis O.
