0.12.17

New Features

• Allow BinaryQuadraticModel.contract_variables() to contract
  variables without an interaction. Previously it raised a
  ValueError.
• Add power_r() generator function to dimod.generators. The
  weights of the generated Ising problems follow a power-law
  distribution with respect to their magnitude.
• Add bin_packing generator function to dimod.generators.
• Add labels keyword argument to
  ConstrainedQuadraticModel.iter_constraint_data() and
  ConstrainedQuadraticModel.iter_violations() methods. The labels
  keyword argument allows a user to generate the data/violations for a
  subset of the constraints. See #1381.
• Add knapsack generator function to dimod.generators.
• Support Python 3.13.
• Add quadratic_assignment generator function to dimod.generators.
