QCoDeS 0.52.0

QCoDeS 0.52.0 (2025-04-03)

Note This will be the last version of QCoDeS to support Python 3.10.

Breaking Changes:

• QCoDeS no longer ships a setup.py script and all package config is done in pyproject.toml
  A version of pip or other package manager supporting PEP621 is required to build from source. #6919
• The QCoDeS dataset sqlite connection class ConnectionPlus has been deprecated and replace with AtomicConnection.
  Unlike ConnectionPlus AtomicConnection is a direct subclass of sqlite3.Connection which enables better type checking
  and will allow QCoDeS to drop the dependency on wrapt. The function make_connection_plus_from is also deprecated and
  it is no longer supported to convert a connection from a sqlite3 connection to a QCoDeS specific connection. #6942
• The QCoDeS deprecation utils including qcodes.utils.deprecate.deprecation_message,
  qcodes.utils.deprecate.issue_deprecation_warning, qcodes.utils.deprecate.deprecate qcodes.utils.deprecate.assert_not_deprecated
  and qcodes.utils.deprecate.assert_deprecated along with their reexports in qcodes, qcodes.utils and qcodes.utils.helpers
  are all deprecated and will be removed in QCoDeS 0.54.0. We recommend using typing_extensions.deprecate as an alternative. #6946

Improved:

• Added 'parameters' argument to the 'plot_dataset' (and 'plot_by_id')
  functions. This enables a choice of which dependent parameters to plot
  (in the case that the plotting of all dependent parameters is not
  desired). #6931
• Save the parameter snapshot under the register_name key in the parameters snapshot in datasets (not the station snapshot), to avoid overwritting the snapshot multiple parameters have identical short_names.
  The parameter snapshot saved under the short name key is kept for backwards compatibility, but will be removed at a later time. #7012

Improved Drivers:

• Added several parameters into the oxford MercuryiPS driver,
  enabling the control of the heaters and the sensing of internal temperatures
  (magnet, PT1, and PT2 stage of cryogenic system).
  Added heater_switch parameter to manage the heater switch status and settings.
  The heater switch control is bound to each WorkerPS, accepting "ON" and "OFF" as inputs.
  Added magnet_temp, pt1_temp, and pt2_temp parameters for reading temperatures
  from different sensors, utilizing the new _temp_parser function.
  Currently, the addresses of temperature sensors are written statically in the driver. #6889

New:

• Added a global callback mechanism to ParameterBase that enables users to
  supply custom callback functions to handle parameter changes. This new feature
  allows for flexible integrations—such as logging changes, updating dashboards, or
  other custom processing—without modifying full snapshot behavior.
  See the PR for details on a usage example. #6934
• A new Validator LiteralValidator was added. This allows validating against the members of a typing.Literal. #7009
