0.12.0.dev0

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.

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.
