0.9.13

Fixes

• DQM.from_numpy_vectors, .set_quadratic and .set_quadratic_case now correctly raise a ValueError when the user attempts to create an interaction between cases in a variable
• BQM.from_numpy_vectors now maintains the correct variable order
• AdjDictBQM biases are no longer 0 dimensional arrays when constructed from a numpy matrix

• Python AdjVectorBQM.from_numpy_vectors and AdjMapBQM.from_numpy_vectors is now much more performant
• Cython DiscreteQuadrataticModel object now uses C++ COO constructors rather than an ad hoc implementation
• gnp_random_bqm generator for randomly connected BQMs

0.9.12

New Features

0.9.11

Changes

• Deprecated SampleSet.append_variables

New Features
