Changes in 3.0.0

================

Backward incompatible change: dropped the support of Python 2.6.

Fix an BytesIO issues that prevents Python 2.7 from serialising a filter.

Changes in 2.3.2

==============

Added hash function to the filter instance.

Changes in 2.3.1

==============

Added union functionality to ScalableBloomFilter.

Changes in 2.2

==============

Replaced the xrange by count, so it is a iterator now.

This fixes overflow error when a large integer is passed

the range_fun.

Changes in 2.1

==============

The tightening ratio is 0.9, and it is consistently used.

Choosing r around 0.8 - 0.9 will result in better average

space usage for wide range of growth, therefore the default

value of mode is set to LARGE_SET_GROWTH.

Changes in 2.0

==============

Made major corrections to the algorithms for both BloomFilter and

ScalableBloomFilter. Not numerically compatible with serialized

representations of filters from previous versions. Specifically,

BloomFilter was more accurate than requested and ScalableBloomFilter

was much less accurate than requested.

Changes in 1.1

==============

Added copy, intersection and union functions to BloomFilter
