QCoDeS 0.44.0 (2024-01-24)
==========================

Breaking Changes:
-----------------

- The deprecated method `DataSetProtocol.cache.to_pandas` has been removed. Use the to_pandas_dataframe or to_pandas_dataframe_dict methods as an alternative. (:pr:`5626`)
- The following long deprecated functions and methods and functionalities have been removed.
  Here ordered by top level module for clarity.

  * ``qcodes.dataset``

      * ``flatten_1D_data_for_plot``

      * ``get_shaped_data_by_runid``

      * ``get_guids_from_run_spec``

      * ``dataset.get_data_as_pandas_dataframe``

      * ``dataset.export_path``

      * ``_conditional_parameter_set``

      * ``_make_nested_setpoints``

      * ``_select_active_actions_delays``

      * ``_create_measurements``

      * ``_extract_paramters_by_type_and_group``

      * ``_build_data_query``

      * ``get_data``

      * ``get_interdeps_from_result_table_name``

      * ``get_values``

      * ``get_setpoints``

      * ``get_guids_from_run_spec``

      * ``data_sets``

      * ``modify_values``

      * ``modify_many_values``

  * ``qcodes.instrument_drivers.devices`` / ``codes.parameters``

    * ``VoltageDivider``

  * ``qcodes.station``

      * Support for driver kwarg in yaml config

      * Support for limits as a string.

  * ``qcodes.utils``

      * ``get_qcodes_version`` (:pr:`5651`)
- The following deprecated instrument drivers have been removed:

  * ``QDevil.QDac`` Use driver from qcodes_contrib_drivers instead.

  * ``Agilent_34400A`` Use Keysight 344xxA drivers or Agilent34401A, Agilent34410A, Agilent34411A instead.

  * ``E8267`` use  ``AgilentE8267C`` instead.

  * ``Agilent_E8527D`` use AgilentE8257D instead.

  The following deprecated instrument driver methods have been removed:

  *  ``KeysightInfiniium``  ``DSOTimeAxisParam.prepare_curvedata``

  *  ``KeysightB1517A.measure_config`` replaced by ``v_measure_range_config`` and ``i_measure_range_config``

  * ``RohdeSchwarz ZNB`` ``RohdeSchwarzZNBChannel.update_traces`` use ``update_lin_traces``


  ``qcodes.utils.deprecate`` decorator has been soft deprecated. In the future qcodes will use the ``deprecated`` decorator from
  the ``typing_extensions`` package (to be part of the std library warnings module from Python 3.13). We recommend anyone else to
  do the same. (:pr:`5655`)


Improved:
---------

- `load_by_run_spec` and `load_by_id` may now optionally load the dataset as a DataSetInMem from an exported netcdf file. This avoids reading
  from the database potentially resulting in better performance. This option is off by default at the moment but can be turned on by setting
  `qcodes.config.dataset.load_from_exported_file` to True. (:pr:`5320`)
- When loading a QCoDeS dataset from a netcdf file using load_from_netcdf and converted to a Xarray dataset using
  ``to_xarray_dataset`` or ``cache.to_xarray_dataset`` we avoid converting the data to QCoDeS format and back to Xarray format.
  This should save time and avoid any potential corner cases when roundtripping the data. (:pr:`5627`)
- Fixed an issue where datasets with categorical setpoints could fail to correctly export to Pandas dataframes or Xarray dataset. (:pr:`5641`)


Improved Drivers:
-----------------

- Lakeshore 335: Add parameter mapping for thermocouple input when using 3060-H option (:pr:`5652`)
