• The following deprecated modules, drivers, and APIs have been removed.

  Removed Modules:

  The following deprecated compatibility modules have been removed. Please import from the locations listed in the
  API documentation <https://microsoft.github.io/Qcodes/api/index.html>_ instead:

  • qcodes.utils.command
  • qcodes.utils.dataset (including qcodes.utils.dataset.doNd)
  • qcodes.utils.helpers
  • qcodes.utils.installation (use qcodes.extensions instead)
  • qcodes.utils.metadata
  • qcodes.utils.plotting
  • qcodes.utils.threading
  • qcodes.utils.validators (use qcodes.validators instead)
  • qcodes.instrument.base
  • qcodes.instrument.delegate.grouped_parameter (use qcodes.parameters instead)
  • qcodes.instrument.function (use qcodes.parameters instead)
  • qcodes.instrument.group_parameter (use qcodes.parameters instead)
  • qcodes.instrument.parameter (use qcodes.parameters instead)
  • qcodes.instrument.specialized_parameters (use qcodes.parameters instead)
  • qcodes.instrument.sweep_values (use qcodes.parameters instead)

  Removed Drivers:

  The following deprecated driver aliases have been removed. Use the replacement drivers listed below:

  • qcodes.instrument_drivers.Lakeshore.Model_325 — use LakeshoreModel325 instead.
  • qcodes.instrument_drivers.Lakeshore.Model_336 — use LakeshoreModel336 instead.
  • qcodes.instrument_drivers.Lakeshore.Model_372 — use LakeshoreModel372 instead.

  Other Changes:

  • DataSet.to_xarray_dataarray_dict, DataSetInMem.to_xarray_dataarray_dict, and
    DataSetCache.to_xarray_dataarray_dict have been removed. Use to_xarray_dataset_dict instead.
  • load_to_xarray_dataarray_dict in qcodes.dataset.exporters.export_to_xarray has been removed.
    Use load_to_xarray_dataset_dict instead.
  • InterDependencies_.non_dependencies property has been removed. Use top_level_parameters instead.
  • ChannelTuple.get_channel_by_name no longer accepts multiple names. Pass a single name to get a single
    channel. Use get_channels_by_name for multiple channels. The argument name has changed from names to name
    to reflect this.
  • The has_current_rating keyword argument to AMIModel430 has been removed as it had no effect.
  • The deprecated import of qcodes.utils.validators from qcodes.utils.__init__ has been removed. Remove expired deprecations #7934

• qcodes.instrument.mockers.ami430.MockAMI430 has been deprecated. This class is unused
  within QCoDeS and is not expected to be used externally. Deprecate MockAMI430 #7972

• A new resource parameter has been added that accepts an already-opened
  pyvisa.resources.MessageBasedResource, allowing a VisaInstrument to be
  constructed from an existing PyVISA resource handle. The resource parameter
  cannot be combined with address, visalib or pyvisa_sim_file. These arguments
  are only used to construct a new resource.

  The resource_manager, visabackend and visalib visa_handle attributes of
  :class:.VisaInstrument have been converted to read-only properties.

  The _address property is deprecated in favour of address.
  The visalib property is deprecated in favour of visabackend.

  The method set_address now takes visalib as an argument. If this
  is not supplied the default visa library will be used. Visa improvments #7978

Improved:

• Fixed to_xarray_dataset failing with a MergeError when exporting
  incomplete measurements where a shared setpoint parameter was treated as a
  coordinate in some sub-datasets and a data variable in others. This could
  happen when the actual data shape did not match the declared shape (e.g. a
  measurement that was interrupted before completion) and one of the sweep axes
  had non-unique values, causing different export code paths to disagree on the
  role of the shared setpoint. More robust export of interrupted datasets #7960

• initialise_database, initialise_or_create_database_at, and initialised_database_at
  now accept more consistent arguments:

  • initialise_database accepts a new db_path parameter to specify the database file
    location directly, instead of always reading from the config.
  • initialised_database_at accepts a new journal_mode parameter, consistent with
    initialise_database and initialise_or_create_database_at. More consistent arguments to db init functions #7967

• The Minicircuits USB SPDT driver now has a minicircuits_usb_spdt optional dependency target,
  allowing installation via pip install qcodes[minicircuits_usb_spdt]. At the moment this is only
  supported on Windows since the vendor only ships a driver for Windows. Add target for minicircuits_usb_spdt driver #7986

Improved Drivers:

• Converted get_error, ramp, pause, zero, reset_quench, set_quenched,
  and reset on AMIModel430 from QCoDeS functions (add_function) to proper methods.
  The zero method now invalidates the field parameter cache and updates the parent
  AMIModel4303D driver's internal setpoint tracking when called on a child instrument.
  Fixed AMIModel4303D to properly set _parent_instrument on child AMIModel430
  instruments during initialization, enabling the safety-check delegation path in
  set_field. Also fixed _request_field_change to correctly call _set_setpoints
  instead of non-existent _set_x/_set_y/_set_z methods. AMI430 improvments #7923
• Add parameter to Keithley2600 driver to enable/disable four-wire measurements. Add param to enable four-wire measurement on Keithley 2600 driver. #7942
• The AMI430SwitchHeater snapshot now skips updating heater-specific parameters
  (state, in_persistent_mode, current, heat_time, cool_time) when
  the switch heater is not enabled. This prevents VISA query failures on real hardware
  when the heater is not installed. Ami snapshot fix #8009
