Comment:

 The missingdata branch has been merged into master. Here's the release
 note mention about the change affecting this:


 {{{
 The <ufunc>.reduce functions evaluates some reductions in a different
 order than in previous versions of NumPy, generally providing higher
 performance. Because of the nature of floating-point arithmetic, this
 may subtly change some results, just as linking NumPy to a different
 BLAS implementations such as MKL can.
 }}}
