Prerelease: no

Release notes: QCoDeS 0.58.0 (2026-05-04) ==========================

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. #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. #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. #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. #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. #8024

• Added calibration due date to Keithley calibration utility functions. #8040
• Fixed `_get_data_from_ds` to correctly handle datasets with incorrect multi-index structure during export by adding a fallback data lookup. #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. #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)
