QCoDeS 0.36.0 (2022-11-29)

Breaking Changes:

• The test_intrument and test_intruments functions are no longer available
  from the toplevel qcodes namespace.
  If you require these functions they must be imported from
  qcodes.instrument_drivers.test. (A few more transitions from units to unit #461`)
• The deprecated imports of Loop, Measure and members of qcodes.data in the toplevel QCoDeS namespace has been
  removed. (Remove deprecated import of loop etc at the top level of qcodes #4674)
• Explicitly setting a sample id in the qcodesrc.json config file has been deprecated. This feature is
  expected to be very lightly used. Please do get in touch if you rely on it. This will eventually
  be replaced by a random string. For the same reason load_by_run_spec will no longer print
  sample_id as part of the output when more than one potential match is found.
  Note that this is different from the sample_name set as part of an experiment which is still supported. (Add random sample to guid #4763)

Improved:

• The sweeps used by doNd has gained the ability to perform a get call after setting the parameter and storing
  that value in the dataset rather than the value set. (Add ability to get parameter after set to dond #4759)
• plot_dataset will now correctly wrap long titles into multiple lines. (Add text-wrapping for extra-long plot titles #4770)
• Keithley calibration: adjust calibration date before saving new calibration (Keithley calibration: adjust calibration date before saving new calibration #4779)
• Visa insturments have gained the pyvisa_sim_file argument. This allows easier instantiation of
  simulated visainstrments in tests (both in QCoDeS and external) as well as use of simulated instruments in
  station yaml files. (Add importlib resources bases import to VisaInstruments #4790)
• dond functions now return the dataset after KeyboardInterrupt or BreakConditionInterrupt.
  Instead of raising the interrupts, they are now logged as warning. (log.warning instead of raise exception if measurement has been interrupted. #4801)
• The function qcodes.dataset.load_from_netcdf now always perservers order of the dependent coordinates
  when loading a netcdf file into memory. (Load coordinates from netcdf in the correct order. #4802)
• Add rundescriber_from_json to dataset public API
  for materializing RunDescriber objects from json strings (Add rundescriber_from_json to dataset public API for loading RunDescriber from json #4811)
• Add RunDescriber, InterDependencies_, ParamSpecTree to dataset public API (Add RunDescriber and friends to dataset public API #4816)
• All public methods avilable in qcodes.dataset that takes a
  path to a db or data file now accepts a pathlib.Path object in addition to a str. (Consistently allow pathlib.Path in all relevant public dataset methods #4818)

New:

• Add a callback to dataset.get_parameter_data.
  This is usefull to track the progress of the data download.
  Since sqlite3 does not allow to keep track of the data loading progress,
  we compute how many sqlite requests correspond to a certain percentage of
  progress which is dictated by a config parameter "callback_percent".
  Then we perform x sql request instead of one, running the callback everytime. (Add a callback to get_parameter_data to follow data loading #4688)
