1.5.0

Fixes

• Docstring formatting fixes #387
• Chain strength documentation fixes #391
• Fix broken documentation links #396

Features

• DWaveCliqueSampler can fail over #395
• Add MockLeapHybridDQMSampler #399

1.4.0

New Features

• Support for problem labels (all samplers now accept an optional label kwarg)
• Label on VirtualGraphComposite flux bias measurements

Fixes

• Hybrid samplers now properly select the latest version of an appropriate hybrid solver
• Python 2 cruft cleanup

1.3.0

New Features

• ReverseBatchStatesComposite now inherits from dimod.Initialized and by default reverse anneals
• ReverseAdvanceComposite now reverse anneals by default with schedule [[0, 1], [1, 0.35], [9, 0.35], [10, 1]]

Fixes

• EmbeddedStructure is now deep copy-able
• Embedding composites now raise correct warnings even when chain strengths are provided as a dict

Changes

• Many dwave.embedding utility functions have been migrated to minorminer, though they are still imported into their original namespaces

1.2.1

Fixes

• Doctest now passes

1.2.0

New Features

• LeapHybridSampler.min_time_limit method
• Improved documentation of LeapHybridDQMSampler
• More sanity checks on time_limit in LeapHybridDQMSampler

Changes

• LeapHybridDQMSampler.sample_dqm's compressed keyword argument has been deprecated in favor of compress

1.1.1

Fixes

• Correctly propagate kwargs through LeapHybridDQMSampler.sample

1.1.0

New Features

• LeapHybridDQMSampler

Fixes

• embed_bqm now always returns a BQM rather than sometimes returning a view

1.0.0

Changes

• All samplers now strongly prefer either a QPU or a hybrid solver (#288). See Sampler behavior changes in 1.0.0 for details.
• Removed deprecated solver_features kwarg in DWaveSampler
• Removed deprecated order_by kwarg in DWave(Clique)Sampler

0.9.13

New Features

• New chain strength tuning methods, uniform_torque_compensation and scaled
• Embedding composites now use uniform_torque_compensation to set the default chain strength
• MockDWaveSampler.sample now accepts **kwarg for greater flexibility when testing

Fixes

• embed_bqm no longer raises an error when EmbeddedStructure and target_adjacency are both provided. It now raises a deprecation warning

0.9.12

Fixes

• Fix bug in DWaveCliqueSampler chain strength formula
