New Features

  • There are three new exceptions: VisualizationError, VisualizationValueError, and VisualizationTypeError. These are now used in the visualization modules when an exception is raised.
  • You can now set the logging level and specify a log file using the environment variables QSIKIT_IBMQ_PROVIDER_LOG_LEVEL and QISKIT_IBMQ_PROVIDER_LOG_FILE, respectively. Note that the name of the logger is qiskit.providers.ibmq.
  • qiskit.providers.ibmq.job.IBMQJob now has a new method scheduling_mode() that returns the scheduling mode the job is in.
  • IQX-related tutorials that used to be in qiskit-iqx-tutorials are now in qiskit-ibmq-provider.


  • now accepts a new boolean parameter descending, which can be used to indicate whether the jobs should be returned in descending or ascending order.
  • qiskit.providers.ibmq.managed.IBMQJobManager now looks at the job limit and waits for old jobs to finish before submitting new ones if the limit has been reached.
  • qiskit.providers.ibmq.IBMQBackend.status() now raises a qiskit.providers.ibmq.IBMQBackendApiProtocolError exception if there was an issue with validating the status.
