[SciPy-User] [ANN] Bottleneck 0.5.0 released

[Keith Goodman]

Bottleneck is a collection of fast NumPy array functions written in
Cython. It contains functions like median, nanmedian, nanargmax,
move_max, rankdata.

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:
- #14 Support python 2.5 by importing `with` statement
- #22 nanmedian wrong for particular ordering of NaN and non-NaN elements
- #26 argpartsort, nanargmin, nanargmax returned wrong dtype on 64-bit Windows
- #29 rankdata and nanrankdata crashed on 64-bit Windows
