Changelog for QCoDeS 0.25.0

The April 2021 release of QCoDeS.

Breaking Changes:

  • get_data_by_id no longer returns data for standalone parameters if there are no dependent parameters in the dataset. For the same reason plot_by_id and plot_dataset will no longer plot these standalone parameters. (2918)
  • xarray exported data no longer exports extra metadata columns under the extra_metadata tag since the extra dictionary level prevents exporting to netcdf (2934)

Deprecation:

  • get_data_by_id and get_shaped_data_by_runid are now deprecated. These functions now all have better alternatives in the build in get_parameter_data as well as Xarray and Pandas exporters. (2921, 2925)

New:

  • SP983c Basel IV amplifier remote control driver (2707)
  • Add support for Keysight 34411A (2927)
  • Added the functionality of getting guids from multiple run ids and directly from database (2930)
  • NumpyJSONEncoder: Add support for the uncertanties' UFloat type (2933)
  • Add conversion between qcodes legacy DataSet and xarray format (2938)

Improved:

  • plot_dataset: Improved performance by using in memory cache when possible to avoid reloading data from disk (2918)
  • contribution guidelines: remove no longer relevant sections and make the sections on naming somewhat less strict (2937)
  • remove double assignment of dataset variable in example notebook of Performing-measurements-using-qcodes-parameters-and-dataset (2926)
  • Update old driver notebooks (Agilent 34400A) docs (2377)
  • Update link from NI VISA to Keysight IO Libraries Suite on 'Getting Started' Doc (2948)
  • Removed ZI UHFLI notebook (2893)

Improved drivers:

  • Significant performance improvement in Tektronix5014 driver (2910)
  • AMI430 3D driver: allow instantiating from names of existing AMI430 instances, next to from AMI430 instances only driver (2949)
  • AMI430 3D driver: add docstring, extra test for initializing from AMI430 by name driver (2951)
  • Driver sr830 update: Add ChannelTrace class and related parameter ch{ch}_datatrace which makes buffered acquisition easier.(2894)

Under the hood:

  • Log sample_name, exp_name, dataset name when Measurement starts (2952)
  • Move private dataset export functions to their own module (2904)
  • Remove wait time test (2935)
  • fix(logger): Disable conditionally start logging for Sphinx documentation (2909)
  • Name legacy test datasets (2950)
  • use python -m pip to upgrade pip in github actions (2955)
