Changelog

Unreleased

v0.6.5 - 2026-06-25

Added / Changed / Maintenance

  • Allow QUBOTools 0.16 while retaining QUBOTools 0.10, 0.11, 0.12, 0.13, 0.14, and 0.15 compatibility.

v0.6.4 - 2026-06-24

Added / Changed / Maintenance

  • Allow QUBOTools 0.15 while retaining QUBOTools 0.10, 0.11, 0.12, 0.13, and 0.14 compatibility.

v0.6.3 - 2026-06-22

Added / Changed / Maintenance

  • Allow QUBOTools 0.14 while retaining QUBOTools 0.10, 0.11, 0.12, and 0.13 compatibility.

v0.6.2 - 2026-06-22

Added / Changed / Maintenance

  • Document public external sampler packages with solver types and source paths, and add the registration workflow for future sampler documentation updates.
  • Add issue and pull request templates for external sampler documentation changes.
  • Harden TagBot permissions for issue-comment release automation.
  • Add release process guardrails and a static release preflight check.

v0.6.1 - 2026-06-11

Added / Changed / Maintenance

  • Add the benchmark metadata contract used by driver release-wave conformance: QUBODrivers.RandomSeed, validate_metadata, total_time, effective_time, and conservative capability traits.
  • Update ExactSampler, IdentitySampler, MIPSampler, and RandomSampler to validate against the benchmark metadata schema.
  • Add default-on benchmark conformance checks to QUBODrivers.test, including metadata, timing, seed determinism, read semantics, time-limit acceptance, and termination-status assertions.
  • Document the metadata schema, seed/read/time-limit semantics, and the new test-suite conformance controls.

v0.6.0 - 2026-06-08

Breaking changes

  • No intentional behavior-breaking changes are included. This is a pre-1.0 minor release because final-read semantics, sampler metadata conventions, and post-sampling callback hooks are part of the public driver-interface API.

Added / Changed / Maintenance

  • Add QUBODrivers.FinalNumberOfReads() and the raw "final_num_reads" attribute so wrappers can distinguish backend search reads from the number of reads returned in the final SampleSet.
  • Standardize sampler metadata conventions for algorithm, backend, execution, optimizer, read counts, seeds, raw status, and structured termination status.
  • Add QUBODrivers.PostSampleCallback() and QUBODrivers.PostSampleTransform() for metadata-only post-processing and explicit sample transformations, including raw-sample preservation when a transform is emitted.
  • Document the QUBODrivers/QUBOTools/ToQUBO boundary for objective bookkeeping, reformulation metadata, original-variable projection, and repair.
  • Allow QUBOTools 0.13 while retaining QUBOTools 0.10, 0.11, and 0.12 compatibility.

v0.5.1 - 2026-06-03

  • Add Dependabot dependency maintenance for Julia environments and GitHub Actions workflows.
  • Skip documentation preview deployment for Dependabot pull requests so docs builds can still validate dependency updates without requiring write access to gh-pages.
  • Add TOML compatibility bounds for the root package environment and build documentation against QUBODrivers 0.5.

v0.5.0 - 2026-05-27

  • Add MIPSampler.Optimizer, an MOI-native exact MIP-backed baseline sampler using a user-supplied MOI optimizer.
  • Document MIP sampler usage and the binary-product linearization reference.
  • Add GLPK-backed MIPSampler parity tests against ExactSampler.

v0.4.0 - 2026-05-22

  • Raise the minimum supported Julia version to 1.10.
  • Add QUBOTools 0.12 compatibility and build the docs against QUBOTools 0.12.
  • Test Julia 1.10 and latest stable Julia in CI.
  • Add QUBODrivers.benchmark for sampler smoke benchmarks and user-provided MOI benchmark models, including read-weighted objective summaries.
