QCoDeS 0.41.0 (2023-10-18)
==========================

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

- The deprecated modules
  `qcodes.data`, `qcodes.loop`, `qcodes.actions`, `qcodes.plots`,
  `qcodes.measure`, `qcodes.extensions.slack`, `qcodes.utils.magic`, qcodes.utils.qt_helpers`
  `qcodes.utils.slack` has been removed.
  The modules can be found in `qcodes_loop <https://github.com/qcodes/qcodes_loop>`_ (:pr:`5367`)
- Update QCoDeS to work with the upcoming release of numpy 2.0.
  The unused attributes `qcodes.utils.types.numpy_non_concrete_floats_instantiable` and
  `qcodes.utils.types.numpy_non_concrete_complex_instantiable` have been removed from QCoDeS. (:pr:`5399`)
- The extra install targets qcodes[slack] and qcodes[qtplot] have been removed.
  All dependencies on slack and pyqtgraph have moved to qcodes_loop. (:pr:`5425`)


New:
----

- QCoDeS now exports data that isn't measured on a grid to a XArray using `MultiIndex`.
  Support for exporting these datasets to NetCDF has also been implemented.
  See `this notebook <../examples/DataSet/Working-With-Pandas-and-XArray.ipynb>`__ for additional details. (:pr:`5334`)
- Add a register_name keyword to the ParameterBase constructor. If supplied, this value
  will be used to register parameters in datasets instead of the default full_name.
  Note that the MultiParameter and ArrayParameter classes do not currently support use
  of the register_name. (:pr:`5381`)
- Large datasets are now exported to NetCDF4 using Dask delayed writer.
  This avoids allocating a large amount of memory to process the whole dataset at the same time.
  Size threshold at the moment is set to approximately 1 GB. (:pr:`5391`)
- The QCoDeS Parameters have now gained the ability to use multiple validators.
  See `here <../examples/Parameters/Parameters.ipynb>`__ for examples of how to use this. (:pr:`5426`)
