0.5.0

Summary

Add support for fast anneal protocol and improve performance.

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.
