QCoDeS 0.58.0 (2026年05月04日)

This will be the last version to support Python 3.11. Python 3.12 will be required starting from QCoDeS 0.59.0.

Breaking Changes:

• All arguments to Parameter classes and subclasses, except name, are now keyword-only.
  Previously deprecated positional arguments have been removed. Remove support for deprecated args in parameters #7911
• Yokogawa GS200: The step and delay arguments of ramp_voltage and ramp_current have been deprecated in favor of the ramp_step and ramp_rate instrument parameters. Make several driver improvements #8025

Improved:

• Errors raised inside a @property getter on a subclass of
  :class:~qcodes.utils.DelegateAttributes (such as :class:~qcodes.instrument.Instrument)
  are now surfaced with their original traceback, instead of being masked by a
  generic AttributeError: ... object and its delegates have no attribute ...
  message. The underlying cause of the failure is now visible in the traceback,
  making misbehaving properties much easier to debug. Acccessing a faulty property of an instrument throws obscure error. #5518
• Parameters using has_control_of are now correctly handled when exporting to
  xarray. Controlled parameters are no longer treated as independent top-level
  parameters, preventing duplicate data rows. Additionally, inferred parameters
  are now included as data variables in the xarray dataset when exporting via the
  pandas-based path, and a warning is logged when the inferred parameter data size
  does not match the expected xarray dataset dimensions. Fix 7717, Improve handling of data variables with inferred parameters + tests #7725
• Add ParameterBaseKWArgs and ParameterKWArgs TypedDicts for typing **kwargs
  forwarded through the Parameter class hierarchy. Subclasses of Parameter can now
  use **kwargs: Unpack[ParameterKWArgs] for statically checked kwargs forwarding. Parameter kwargs dict #8024
• Added calibration due date to Keithley calibration utility functions. Add calibration due date to Keithley save_calibration util func #8040
• Fixed _get_data_from_ds to correctly handle datasets with incorrect multi-index structure during export by adding a fallback data lookup. fix(dataset): handle plot for dataset with incorrect parameter data #8080

Improved Drivers:

• The TektronixAWG5014 driver has been refactored to use InstrumentChannel
  submodules. Per-channel parameters (e.g. amp, offset, state) are now
  accessed via awg.ch1.amp instead of awg.ch1_amp, and marker parameters
  via awg.ch1.m1.high instead of awg.ch1_m1_high. The old flat attribute
  names still work but emit a deprecation warning. The example notebook has been
  updated accordingly. Awg5014 with channels #7996
• Keysight 344xxA: Add SCPI mnemonics ('MIN', 'MAX', 'DEF') to allowed values where allowed
  Oxford Mercury IPS: Allow setting current ramp rate and target
  Oxford Triton: Also assume magnet is not available if there is a communication timeout
  Yokagawa GS200 Program: Validate program times on multiples of the internal clock rate of 0.1s
  Yokagawa GS200 Program: Only add trigger parameter if monitor option is installed
  Yokagawa GS200 Program: Add get parser to count; allow setting to SCPI mnemonics 'MIN', 'MAX'.
  Yokagawa GS200 Program: Add hold(), pause(), cont() methods.
  Yokagawa GS200: Add parameters reading out device registers (status_byte, standard_event_register, extended_event_register, condition_register)
