# Bottleneck 0.5.0

Release date: 2011-06-13

The fifth release of bottleneck adds four new functions, comes in a single source distribution instead of separate 32 and 64 bit versions, and contains bug fixes.

J. David Lee wrote the C-code implementation of the double heap moving window median.

## New functions

- move_median(), moving window median

- partsort(), partial sort

- argpartsort()

- ss(), sum of squares, faster version of scipy.stats.ss

## Changes

- Single source distribution instead of separate 32 and 64 bit versions

- nanmax and nanmin now follow Numpy 1.6 (not 1.5.1) when input is all NaN

## Bug fixes

- Support python 2.5 by importing with statement (#14)

- nanmedian wrong for particular ordering of NaN and non-NaN elements (#22)

- argpartsort, nanargmin, nanargmax returned wrong dtype on 64-bit Windows (#26)

- rankdata and nanrankdata crashed on 64-bit Windows (#29)
