QCoDeS 0.37.0 (2023-01-26)
==========================

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

- ``InstrumentBase.ancestors`` now returns a tuple of ancestors
  to the current Instrument, InstrumentChannel or InstrumentModule and not a list.

  ``dond ``, ``do1d`` etc. now returns tuples of Matplotlib axes and colorbars
  when plotting and not lists. (:pr:`4894`)
- Datasets are now exported to a folder next to the database by default rather then to the users home folder.
  Note that if you had specifically configured this in a local config file this should be updated too for the
  change to take effect. (:pr:`4899`)
- DriverTestCase has been moved from `qcodes.instrument_drivers.test` to `qcodes.tests.driver_test_case`. (:pr:`4922`)
- `qcodes.instrument_drivers.VoltageDivider` and `qcodes.instrument_drivers.devices.VoltageDivider` has
  been deprecated. Its functionality is better implemented in `qcodes.parameters.DelegateParameter` which
  is also significantly better tested and more general. (:pr:`4923`)
- The QDevil QDAC 1 driver has been migrated to qcodes_contrib_drivers and is included from version
  0.18.0. The driver in QCoDeS is deprecated and will be removed in a future release. (:pr:`4932`)
- Remove deprecated Mercury iPS driver
  ``qcodes.instrument_drivers.oxford.mercuryiPS.MercuryiPS``,
  use ``qcodes.instrument_drivers.oxford.OxfordMercuryiPS``
  instead. (:pr:`4936`)


Improved:
---------

- When a dataset is exported an optional user supplied entry point is called. See
  `here <../examples/DataSet/Exporting-data-to-other-file-formats.html#Automatically-post-process-exported-datasets.>`__
  for more details. (:pr:`4857`)
- PyVISA ``1.13`` is now supported. (:pr:`4895`)
- ``validate`` method of ``DelegateParameter`` now also validates the given value
  against the validator of the source parameter (if source parameter is present). (:pr:`4870`)
- The dataset logic has been updated to ensure that if you set an already completed
  dataset as completed the completion timestamp will not be updated. (:pr:`4876`)
- Update the pyqtgraph plot backend for upstream changes in pyqtgraph. (:pr:`4886`)
- QcoDeS is now typechecked with Pyright in addition to mypy. This should give a significantly
  better user experience when working in VS Code. (:pr:`4938`)


Improved Drivers:
-----------------

- The Minicircuits USB SPDT driver now supports running with the more modern version of the driver DLL `mcl_RF_Switch_Controller_NET45.dll` (:pr:`4623`)
- Two parameters are added to the `Keysight.N51x1` class, conditioned on it having the 'UNW' option:
      1. Having the pulse modulation status on or off.
      2. Setting it to 'internal' or 'external'.

  From the Keysight manual:
      1. This command enables or disables pulse modulation for the selected path.
      2. This command sets the source of the pulse modulation. (:pr:`4840`)


Under the hood:
---------------

- Improve performance of parameter validator. (:pr:`4887`)
