Bug Fixes

• Update sample set creation in dwave.cloud.computation.Future to support dimod 0.12.18+. Previously, wait_id() method used to be added to the from_future-created sample sets in the cloud-client, and now the SampleSet interface propagates wait_id from the future by default. See dimod#1392 and dwave-system#540.

dwave-optimization 0.3.0 ➞ 0.4.2

New Features

• Add capacitated vehicle routing problem with time windows generator.
  See #104.

• Reduce the number of symbols in the model returned by
  job_shop_scheduling() generator.

• Add Array::integral(), Array::max(), and Array::min()
  overloads for all existing C++ nodes.

• Add C++ is_integer() function.

• Support Python 3.13.

• Model.add_constraints() now returns the symbol for the constraint.

• Fully support scalar (0-dimensional) indices for advanced indexing
  operations, e.g. A[i, :, j, :] where i and j are nodes with
  scalar output. Previously, this would work only if the final output
  of the indexing operation was also scalar.

• Add C++ DisjointListsNode::set_state() method which allows for
  setting the state of disjoint lists directly.

• Add C++ XorNode and Python Xor symbol. Xor propagates the
  logical exclusive-or of its two predecessors element-wise. See #125.

• Add C++ AnyNode. See #148.

• Add Any symbol and ArraySymbol.any() method. See #148.

• Change the formulation of the job_shop_scheduling() generator to
  remove redundant list variables and replace them with a disjunctive
  non-overlapping constraint between each pair of jobs on the
  machines.

• Raise clearer error messages when trying to use out-of-bounds
  indices.

• Add C++ Graph::remove_unused_nodes() method to remove nodes that
  are not used in the objective or constraints. See #41.

• Add Python Model.remove_unused_symbols() method to remove nodes
  that are not used in the objective or constraints. See #41.

• Improve the move/copy behavior of C++ ArrayIterator.

• Add C++ index raveling-unraveling utilities functions.

• Add C++ PartialReduceNode.

• Add Python PartialSum symbol and added axis keyword in
  ArraySymbol.sum() function.

• Implement C++ BinaryOpNode::sizeinfo() overload.

• Add C++ ModulusNode and Python Modulus symbol. Modulus
  propagates the modulus of its two predecessors element-wise. Modulus
  symbols may be created with either the % operator or the mod()
  function in dwave.optimization.mathematical. See #156.

Upgrade Notes

• Using advanced indexing nodes with indexing arrays that have a
  higher dimension than one (e.g. A[:, i, :, j] where i and j
  are 2d arrays) has been disabled. Previously, it was possible to
  construct models that used this functionality, but the behavior of
  the model during state initialization and propagation may not have
  been correct.

• Remove redundant list variables in the job_shop_scheduling()
  generator and add disjunctive non-overlapping constraints between
  each pair of jobs on the machines.

• Drop support for Python 3.8.

• Change C++ ArrayIterator to no longer have ownership of its fill
  value when masked.

• Remove vartypes.hpp. The Vartype enum was not used by any other
  classes or functions.

Bug Fixes

• Fix combined indexing. Previously indexing an array symbol by a
  mixture of arrays, integers, and non-empty slices would always
  result in an error.

• Update AdvancedIndexingNode to check the indices of its indexing
  arrays to prevent out-of-bounds access.

• Fix the case of using scalar indices in an advanced indexing
  operation where the indices were not grouped, e.g. A[:, i, :, j],
  which was technically unsupported but no errors were raised. This
  could also lead to segfaults during state initialization or
  propagation.

• Update C++ UnaryOpNode to correctly handle dynamic predecessors.

• Fix the possibility of creating a dangling reference when using a
  masked C++ ArrayIterator.

• Implement missing overloads for NaryMaximumNode::max(),
  NaryMaximumNode::min(), and NaryMaximumNode::integral().

• Implement missing overloads for NaryMinimumNode::max(),
  NaryMinimumNode::min(), and NaryMinimumNode::integral().

• Fix two bugs in advanced indexing node propogation in the case of a
  non-const main array with dynamic indexers, e.g. A[x] where A is
  a 1d integer decision variable and x is a list. The first bug
  could cause segfaults during propagation, and the second could lead
  to incorrect output if both arrays were changed during propagation.

• Update the logic in the
  capacitated_vehicle_routing_with_time_windows() generator function
  to correctly account for asymmetric time-distance matrices.

• Fix the type information for ArraySymbol.__abs__().

• Fix serializing models with binary operations over dynamic
  predecessors. Previously it was not possible to estimate the state
  size which caused serialization to fail.

dwave-preprocessing 0.6.6 ➞ 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](...

8.0.1

Changelog

dwave-cloud-client 0.13.0 ➞ 0.13.1

New Features

• Configuration constants like default region and default API endpoints are now available in a new module dwave.cloud.config.constants.

  Configuration-related exceptions are now available in a new module dwave.cloud.config.exceptions.

  dwave.cloud.config module (with submodules) is now free from dependencies on other submodules, and it's safe to be imported in any cloud-client context.

Deprecation Notes

• Use of dwave.cloud.api.constants to access default configuration constants is deprecated in dwave-cloud-client==0.13.1 in favor of a new config module dwave.cloud.config.constants, and will be disabled in dwave-cloud-client==0.14.0.

Bug Fixes

• Fix a circular import error. See #669.

8.0.0

Changelog

dimod 0.12.16 ➞ 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.

dwave-cloud-client 0.12.1 ➞ 0.13.0

Prelude

• Solver metadata is now cached on disk, and validated using conditional requests, resulting in faster Client/Sampler initialization.
• Problem status is now observed using long polling, resulting in shorter delays between problem solved and solution downloaded.
• Problem data is now compressed for upload, resulting in faster problem submit on slower networks.
• Problem preprocessing time during submit is cut in half.
• Best case median QPU sample time now ranges from 260ms to 330ms.

New Features

• Enable QPU problem data compression on upload using deflate content encoding.

  Compression is controlled with a new config option, compress_qpu_problem_data, defaulting to true, and it can be turned off either in config file or via Client() kwarg. See #622.

• Add long polling as problem status/answer polling strategy.

  We add the following config options: poll_strategy ("backoff" is the current default, "long-polling" is the new strategy), poll_wait_time, and poll_pause. See #648.

• Add timeout keyword argument to api.resources.Problems.get_problem_status() and api.resources.Problems.get_problem_statuses() methods.

  Use it to enable long polling on problem status API endpoint. The connection is closed (server-side) when at least one problem completes, or the timeout (in seconds) elapses, whatever comes first. See #649.

• Add support for retrieving filtered solver configuration to dwave.cloud.api.resources.Solvers methods. See #644.

• Add API response caching support to dwave.cloud.api interface. Cache is validated using a conditional request based on ETag. See #645.

• Poll for problem-status update using long-polling strategy by default. See #662.

  Long-polling strategy enables faster status-change propagation to the client, especially for longer jobs, or during heavy QPU usage.

• Speed-up function calls that dispatch events by short-circuiting the dispatch in case no event handlers are registered. See #660.

• Add timeout keyword argument to api.resources.Problems.get_problem() method.

  Use it to enable long polling on problem fetch API endpoint. The connection is closed (server-side) when the problem completes, or the timeout (in seconds) elapses, whatever comes first. In case problem completed in time, problem answer is returned in addition to problem status (which is always returned). See #657.

• Enable regions metadata API cache control in dwave.cloud.regions.get_regions() by switching to api.Regions built-in caching session. See #647.

• Speed-up JSON encoding and decoding by switching to orjson. See #423.

• Parse Cache-Control header field if present in API response, and use it to guide local caching policy.

  This means dwave.cloud.api.DWaveAPIClient and dwave.cloud.api.resource classes now respect origin server response caching policy. See #646.

• Cache solver metadata on disk, using conditional requests for cache validation (update).

  Static and dynamic parts of solver metadata are fetched and stored separately, to enable efficient caching.

  See #613.

• Lazily import Client/Solver/Future in the top-level namespace, dwave.cloud. Direct imports are preferred, e.g. from dwave.cloud.client import Client, but the widely-used way (from dwave.cloud import Client) is still supported for backwards compatibility.

  Similarly we now lazily import old namespaces with client type as submodule, e.g. dwave.cloud.qpu.

  The main benefit of such lazy imports is import performance, as "heavy" symbols are only imported when explicitly needed/asked for. See #643.

• Speed-up imports by slightly decoupling submodules. See #643.

• Speed-up dwave.cloud.utils.qubo.active_qubits utility function by ~50%, and dwave.cloud.coders.encode_problem_as_qp by 20-30%. See #661.

• Speed-up QPU problem sampling when problem submitted as BQM by 40%. For best performance, keep linear and quadratic biases in dicts. See #661.

• Cache dynamic solver metadata for up to 15 minutes, unless defined differently by API cache control response header. See #663.

Upgrade Notes

• Short polling with exponential backoff is not used by default anymore, but it is still available. If for some reason you want to use it, set:

  poll_strategy = backoff
  

  configuration parameter in your config file, or the keyword argument in calls to Client() or Client.from_config(). See #662.

• Config attributes previously available directly on Client instance, deprecated in dwave-cloud-client==0.11.0, are removed in dwave-cloud-client==0.13.0.

  Use config model (dwave.cloud.config.models.ClientConfig) available as Client.config to access client configuration instead.

  Path to most attributes translates directly. For example, Client.region is now available as Client.config.region. One attribute has been renamed (Client.default_solver is now Client.config.solver), and all Client.poll_* config options are consolidated under Client.config.polling_schedule.*. Similarly Client.http_retry_* options are now available under Client.config.request_retry.*. See #664.

Deprecation Notes

• dwave.cloud.utils.coders.NumpyEncoder is deprecated and will be removed in dwave-cloud-client==0.14.0. Use orjson.dumps() with OPT_SERIALIZE_NUMPY option instead. See #652.

• Shorthand import paths for specialized Clients (for qpu, sw and hybrid) are deprecated in dwave-cloud-client==0.12.2 and will be removed in dwave-cloud-client==0.14.0. Instead, use the full import path, e.g. from dwave.cloud.client.qpu import Client, instead of from dwave.cloud.qpu import Client. See #643.

Bug Fixes

• Defer SQLite connect in @cached.ondisk() until actually needed. Also, verify cache thread/process-safety and forking support. See #642.

• Fix get_cache_dir() to not create the cache directory by default. Creation is now optional and controlled with create argument. This makes it consistent with other config path functions. See #642.

• Fix possible race condition during cache directory create. See homebase#37, #642.

• During solver metadata filtering, treat solver status as a dynamic field. This is to handle an edge case when solver is marked offline, but it's still available via API. See #663.

dwave-hybrid 0.6.11 ➞ 0.6.12

New Features

• Add support for cubic lattice embeddings on Zephyr to make_origin_embedding. See #295.

dwave-gate 0.3.1 ➞ 0.3.2

New Features

• Support, and build with, NumPy 2.0

Bug Fixes

• Updates the circuit so that conditional parametric gates are evaluated in place when appended to the active circuit, fixing an issue where changes to these gates post application are not propagated to the circuit.

• Remove PyQIR version check as it's been added as an optional dependency. A supported version can now be installed directly with pip install dwave-gate[qir].

Changelog

dimod 0.12.14 ➞ 0.12.15

New Features

• Add C++ QuadraticModelBase::remove_interactions() method.

• Add dimod.generators.random_binary_paint_shop_problem() binary paint shop problem generator.

• Add an abstract method QuadraticViewsMixin.add_quadratic().

• Add a method QuadraticViewsMixin.add_quadratic_from() to add quadratic interactions. This method is intended to be used as follows: ConstrainedQuadraticModel.objective.add_quadratic_from(), similarly to ConstrainedQuadraticModel.objective.add_linear_from().

• Add check_overlaps keyword argument to ConstrainedQuadraticModel.add_discrete(), see #1364.

Upgrade Notes

• All sublcasses of QuadraticViewsMixin, including ObjectiveView, QuadraticModel and BinaryQuadraticModel, now require to have the method add_quadratic().

dwave-cloud-client 0.11.4 ➞ 0.12.0

New Features

• Add support for binary-ref answer encoding format, where answer data is not immediately present in the answer, but on an URI referenced in the answer response.

• Add dwave.cloud.computation.Future.answer_data property to hold the answer data of a resolved future. A call to .answer_data will block until computation future is resolved.

• Add dwave.cloud.api.models.UnstructuredProblemAnswerBinaryRef model, a subclass of ProblemAnswer for binary-ref answers, and a method for downloading answer data (resolving binary-ref), dwave.cloud.api.resources.Problems.get_answer_data.

• Add support for nonlinear unstructured solvers with dwave.cloud.solver.NLSolver.

• Add request/response logging to AuthFlow/OAuth2Session.

• Add basic support for structured logs (JSON output).

• Enable log format control with DWAVE_LOG_FORMAT env variable (set to "json" for structured output.

Upgrade Notes

• dwave.cloud.utils module has been split into the following submodules: dwave.cloud.utils.cli, dwave.cloud.utils.coders, dwave.cloud.utils.decorators, dwave.cloud.utils.dist, dwave.cloud.utils.exception, dwave.cloud.utils.http, dwave.cloud.utils.logging, dwave.cloud.utils.qubo, and dwave.cloud.utils.time.

  First reason for doing this was code clean-up (including adding type annotations), but a more important reason is that this will enable import time optimization in the future. And that's why we break backwards compatibility by not importing everything back into the top-level utils namespace.

  The utils module is considered Ocean-internal as is, so this move shouldn't affect user's code.

• Positional arguments in dwave.cloud.Client constructor, deprecated in 0.10.0, are removed in 0.12.0. Use keyword arguments instead.

• Alias keys samples and occurrences (for solutions and num_occurrences) in the results dict of dwave.cloud.computation.Future.result(), deprecated in 0.8.0, are now finally removed in 0.12.0. We'll try to keep the result dict as close to raw data returned by SAPI as possible. Postprocessed data is instead available via dwave.cloud.computation.Future properties.

Bug Fixes

• Fix a possible race condition when multiple threads try to resolve remote computation results. A special case of this occurs on binary answer download from a reference link. See #624.

• Log failing request/response details in the low-level API client.

• Suppress logging output from the cloud-client by default (as recommended for libraries).

• Format log record date/time according to ISO 8601.

dwave-inspector 0.4.4 ➞ 0.5.0

New Features

• Add support for fast anneal protocol. Display the new solver parameter fast_anneal and the new solver property fast_anneal_time_range in the visualizer. See #170

• Replace builtin JSON encoder with orjson, achieving 2-5x speed-up of problem and solver API endpoints.

• Replace WSGIAsyncServer with dwave.cloud.auth.server.BackgroundAppServer, a more robust and stable multi-threaded server. By using a multi-threaded server we improve the visualizer app load time, as browsers can download static files and make API requests in parallel now. See #165.

Upgrade Notes

• dwave.inspector.utils.NumpyJSONProvider is removed and no longer available. Use orjson.dumps with option=orjson.OPT_SERIALIZE_NUMPY instead.

• Minimal version of dwave-cloud-client required is now 0.11.0 to support #165 and fix #164.

Bug Fixes

• Omit legacy solver parameters, like num_spin_reversal_transforms and postprocessing params (postprocess, beta, chains) from the visualizer. See #166 and #168.

• Improve performance of the inspector server by postprocessing solver data inplace, saving one deep copy of solver metadata (~600kB for Advantage) on each API request of solver data.

dwave-system 1.23.0 ➞ 1.24.0

New Features

• Conversion from flux_biases (units of Phi0) to h (unitless) and vice-versa. See dwavesystems/dwave-system#513.

Bug Fixes

• Adapt MockLeapHybridSolver to work with cloud-client 0.11.3+. See dwavesystems/dwave-system#515.

6.9.0

Changelog

dwave-cloud-client 0.11.2 ➞ 0.11.3

Bug Fixes

• Use fixed authorization success URL, without any authorization query parameters appended (to minimize exposure), as they are not needed on the authorization server's success page.

• Improve CSRF protection on localhost redirect URI during authorization code exchange. Previously, state was verified only if supplied. Now it's mandatory. Please note this is an additional CSRF protection on top of the PKCE, just in case PKCE is not supported (or properly implemented) server-side.

• Fix PKCE support in dwave.cloud.auth.flow.AuthFlow by properly including code_verifier in fetch token (code exchange) requests. See #605.

• Remove circular references in dwave.cloud.computation.Future to enable easier garbage collection and lower memory footprint. See #601.

• Use a consistent User-Agent value for all API and non-API requests made by Client, api.Client and auth.flow client.

• Speed-up User-Agent string construction significantly (10ms to 5us).

dwave-hybrid 0.6.10 ➞ 0.6.11

New Features

• Add Python 3.12 support. See dwavesystems/dwave-hybrid#289.

• Add support for Kings graph in large neighborhood search. See dwavesystems/dwave-hybrid#290.

• Enable optional metadata tracking in LNLS (LatticeLNLS and LatticeLNLSSampler). See dwavesystems/dwave-hybrid#292.

Fixes

• Fix docs build. See dwavesystems/dwave-hybrid#291.

• Use more specific assertions and assertEqual. See dwavesystems/dwave-hybrid#293.

Upgrade Notes

• Drop Python 3.7 support and refresh CI. See dwavesystems/dwave-hybrid#288.
