1.0.0

Prelude

Create dwave-graphs package based off dwave-networkx.
dwave_networkx namespace is renamed to dwave.graphs.

Binary quadratic model (i.e. Ising model and QUBO) generators have been
moved from dwave.graphs.algorithms to dimod.generators.

New Features

• Add support for Python 3.14.

• Modernize package config.

Upgrade Notes

• Drop support for Python 3.9.

• Drop support for dimod<0.12.

• Remove deprecated Chimera and Pegasus coordinates transformation alias
  methods (int/tuple/etc in favor of explicit e.g.
  chimera_to_linear).

• Remove deprecated is_matching and is_maximal_matching functions
  from dwave.graphs.algorithms.matching. Use the NetworkX
  implementations instead.

• Drop the default sampler interface previously available in
  dwave-networkx. Some algorithms now explicitly require a sampler.

• Drop utils and utils.decorators submodules, as well as the
  @binary_quadratic_model_sampler decorator.

• All BQM/Ising/QUBO generators from dwave.graphs.algorithms have been
  migrated to dimod.generators (released in dimod==0.12.22):
  • min_vertex_color_qubo and vertex_color_qubo removed from
    dwave.graphs.algorithms.coloring in favor of min_vertex_coloring
    and vertex_coloring from dimod.generators.coloring,
  • dwave.graphs.algorithms.markov.markov_network_bqm removed in favor
    of dimod.generators.markov.markov_network,
  • matching_bqm, maximal_matching_bqm and
    min_maximal_matching_bqm removed from
    dwave.graphs.algorithms.matching in favor of maximal_matching
    and min_maximal_matching from dimod.generators.matching,
  • dwave.graphs.algorithms.partition.graph_partition_cqm removed in
    favor of dimod.generators.partition.graph_partition,
  • dwave.graphs.algorithms.social.structural_imbalance_ising removed
    in favor of dimod.generators.social.structural_imbalance and
  • dwave.graphs.algorithms.tsp.traveling_salesperson_qubo removed in
    favor of dimod.generators.tsp.traveling_salesperson.

• Drop support for dimod<0.12.22.

• Drop vertex_color and min_vertex_color aliases in favor of
  vertex_coloring and min_vertex_coloring for consistency.

• Drop support for NumPy 1.x.

• Replace dev/test/docs requirements.txt files with Dependency Groups
  (PEP-735).

• dwave.graphs.generators renamed to dwave.graphs.topologies.

• Topology specific coloring functions, zephyr_four_color(),
  pegasus_four_color(), and chimera_two_color(), are moved from
  dwave.graphs.topologies to dwave.graphs.algorithms.coloring.
