0.6.11

New Features

• Add support for Python 3.14.

Upgrade Notes

• Drop support for Python 3.9.

0.6.10

Prelude

Add srts option to SpinReversalTransformComposite

New Features

• Allow non-random specification of spin reversal transforms.

0.6.9

New Features

• Propagate SampleSet.info from child sampler in SpinReversalTransformComposite in the unambiguous case of a single spin reversal transform. See dimod#111, dwave-system#564 and #147.

Upgrade Notes

• Switch from pkgutil-style namespace package to native namespace package (PEP 420). While native namespace packages and pkgutil-style namespace packages are largely compatible, we recommend using only native ones going forward. See #155.

0.6.8

New Features

• All dwave.preprocessing.composites.* are now scoped (implement dimod.Scoped behavior), i.e. they can be used as a context manager.

Bug Fixes

• Fix inheritance in SpinReversalTransformComposite so that composite attributes override sampler attributes.

  See #150.

0.6.7

New Features

• Support Python 3.13.

Bug Fixes

• Fix SpinReversalTransformComposite's handling of child samplers
  that alter the variable order. Previously the spin reversal
  transforms would not be correctly unapplied.
  See #142.

0.6.6

New Features

• Speed up the removal of small biases in presolve.
• Support NumPy 2.0. Also, no longer require NumPy at build-time.

0.6.5

New Features

• Build with dimod 0.12.14. This speeds up the removal of small biases in presolve.

0.6.4

New Features

• Build C++ extensions with Cython 3.
• Build wheels for Python 3.12.

0.6.3

Bug Fixes

• Fix ImportError being raised on Windows when other dwave namespace packages are installed after dwave-preprocessing. See #130.

0.6.2

Bug Fixes

• Fix the handling of quadratic constraints in presolve. Previously fixing variables in quadratic constraints would result in memory errors. See dimod#1351.
