# Bottleneck 0.3.0

Release date: 2010-01-19

The third release of Bottleneck is twice as fast for small input arrays and contains 10 new functions.

## Faster

- All functions are faster (less overhead in selector functions)

## New functions

- nansum()

- move_sum()

- move_nansum()

- move_mean()

- move_std()

- move_nanstd()

- move_min()

- move_nanmin()

- move_max()

- move_nanmax()

## Enhancements

- You can now specify the dtype and axis to use in the benchmark timings

- Improved documentation and more unit tests

## Breaks from 0.2.0

- Moving window functions now default to axis=-1 instead of axis=0

- Low-level moving window selector functions no longer take window as input

## Bug fix

- int input array resulted in call to slow, non-cython version of move_nanmean
