0.8.5

New Features

• SampleSet.truncate method
• BinaryQuadraticModel.to_serializable bias_dtype and bytes_type parameters

Fixes

• BinaryQuadraticModels are now pickleable in python2.7
• Some bug fixes in BinaryQuadraticModel.to_serializable

0.8.4

New Features

• assert_bqm_almost_equal function for testing
• ScaleComposite
• sample_column optional keyword argument for SampleSet.to_pandas_df
• sample_dict_cast optional keyword argument for SampleSet.data

Fixes

• BQM.normalize now ignores ignored variables/interactions when determining scale

0.8.3

New Features

• Faster BQM.add_interaction
• HigherOrderComposite
• reverse kwarg for SampleSet.data
• BQM alias for BinaryQuadraticModel
• SampleSet.__str__ for nicer printing of samplesets

Fixes

• Fix empty SampleSet
• Fix import warning for collections package in python 3.7
• Remove unnecessary type check in BQM.scale

0.8.2

Bug Fixes

• Return dict from BinaryQuadraticModel.to_ising rather than LinearView/QuadraticView

0.8.1

New Features

• concatenate function for combining sample sets
• SampleSet.aggregate method to aggregate repeated samples
• SampleSet.from_samples_bqm constructor to construct sample sets from raw samples and a binary quadratic model

0.8.0

Changes

• Removed OrderedBinaryQuadraticModel
• Change the way the BinaryQuadraticModel stores the biases to speed up calculations and to save memory
• Deprecated Response in favour of SampleSet. Response is targeted to be removed in 0.9.0 release
• Updated reference samples and composites to use SampleSet
• Moved dimod.io namespace under dimod.serialization
• Removed dimod.embedding subpackage, it is now part of dwave-system under dwave.embedding namespace.
