2025.12.9

New Features

• Add dwave.experimental.automorphism submodule with a function to calculate
  the Schreier-Sims representation of a graph, as well as the number of
  automorphisms, vertex orbits, and edge orbits.

• Add dwave.experimental.multicolor_anneal submodule with a utility
  function to fetch available annealing lines and their properties.

• Add support for Python 3.14.

• Add support for solver name pattern matching in fast reverse anneal
  schedules. See #23.

• "x_polarizing_schedules" in sampling_params is detected as a
  symmetry-breaking parameter, allowing the symmetry-detection
  functionality in shimming routines to operate correctly for multicolor
  annealing.

  A utility is added that assigns anneal lines to Advantage2 processor
  nodes under the 6-annealing line scheme most often used. This function
  does not require a client, but is compatible with client-returned
  color assignments.

Upgrade Notes

• Drop support for Python 3.9.

Other Notes

• Add examples of embedding graphs with line-wise assignment
  restrictions.

2025.11.28

Other Notes

• Update solver name in fast-reverse-anneal schedules data to
  "Advantage2_research1.4". Schedules data remains unchanged.

2025.10.24

Other Notes

• Update solver name in fast-reverse-anneal schedules data to "Advantage2_research1.3". Schedules data remains unchanged.

2025.10.3

New Features

• Allow shimming to zero magnetization for a set of programmings differing by sampling_params.
  See #12.

• Implement hypergradient descent (arXiv:1703.04782B) for automation of learning rates as default option
  in shim_flux_biases(). See #10.

Bug Fixes

• Fix incorrect inversion of predicted fast-reverse-anneal schedules in time by updating the linear-exponential line shape parameters. See #14.

• Upgrade dependency packages version bounds to support Ocean 9.

2025.8.13

New Features
