Release date: 2013-09-10

## Enhancements

- bn.rankdata() is twice as fast (with input a = np.random.rand(1000000))

- C files now included in github repo; cython not needed to try latest

- C files are now generated with Cython 0.19.1 instead of 0.16

- Test bottleneck across multiple python/numpy versions using tox

- Source tarball size cut in half

## Bug fixes

- move_std, move_nanstd return inappropriate NaNs (sqrt of negative #) (#50)

- make test fails on some computers (#52)

- scipy optional yet some unit tests depend on scipy (#57)

- now works on Mac OS X 10.8 using clang compiler (#49, #55)

- nanstd([1.0], ddof=1) and nanvar([1.0], ddof=1) crash (#60)
