Migrating from old versions

​

Breaking changes

• Body has been renamed to input, and is always a JSON payload. The format field in input replaces lang as a means of controlling what kind of input is being run.
• Results are no longer served alongside the job body when fetching jobs; now use the results_url field to fetch.
• (v0.1 only) Calibrations endpoints has been deprecated in favor of Characterizations.

​

New features

• Error mitigation is now controllable via API. Debiasing can improve performance via randomized qubit mappings and intelligent post-processing of noise.
• Ability to specify target hardware generation on Job creation. (e.g. qpu.aria-1)

​

Non-breaking changes

• Histogram example expanded to include scientific notation for a JSON numeric value.
