QCoDeS 0.35.0b1 (2022-07-08)

This is a beta release of the upcoming QCoDeS 0.35.0 release.

In this release a large refactoring of the QCoDeS modules organization has taken place.
Among other changes the instrument module has been split into a parameters and
instrument module, the dond functions have been moved to the dataset module
and several methods removed from the public API of the utils module.

The new API is documented in the :ref:api section of the QCoDeS homepage.

Going forward we aim to establish a policy where the QCoDeS public API is defined
by modules explicitly documented in the :ref:api and importable from submodules at most
one level deep. I.e. from qcodes.instrument import InstrumentChannel is supported but
from qcodes.instrument.channel import InstrumentChannel is considered unsupported.

Importing from previously existing locations should continue to work
but it is recommended to update to the new API.
In the future we may deprecate and eventually remove these modules
but no firm date is set for this.

Please report any issues you may see with importing from the previously existing API
or if you depend on any functions, classes etc. not available from the new public API.

Breaking Changes:

• Removed deprecated units property from DataArray. (Remove deprecated units from data array #4358)
• Removed deprecated qcodes.version module. Use qcodes.__version__ (Remove deprecated version module #4307)

Improved:

• :func:qcodes.dataset.doNd now logs more information about how parameters are
  unpacked and grouped making it easier to debug. (Improve logging in doNd #4288)
• do_nd: save plot with 'tight' bbox to prevent tick marks with long labels
  pusing out the axis label out of the canvas window and not visible (do_nd: save plot with 'tight' bbox #4360)
• Significant refactor of internal modules and public API (Remove slack and link to announcements #4357, API: Split metadata module and make public #4355,
  remove old threading docs #4353, API: update instrument drivers to use public api #4351, Api: plotting #4350, API: Make numpy utils public #4349, API: refactor threading and make public #4348, API: Document magic and slack as legacy #4334, Move all members of utils.helpers to more descriptive locations and either make public or make part of individual modules #4330,
  move attribute related functions to own submodule and make public #4326, Add public api for installation info functions #4316, API: Add DelatedKeyboardInterrupt and depreacate to api #4309, Remove deprecated version module #4307, API: Make numpyJSONencoder public #4306, API: Make validators a top level module #4300, Docs: add api docs for interactive_widget #4294,
  API: Move command module into parametes and undocument #4286, API: Split internal instrument.base.py module #4283, Refactor internal parameters api #4275, Move parameter docs to module #4274, Add autosummary for the parameters module #4272, Document calibration module #4266, Create public interface and docs for small modules #4237,
  Public API of logging module #4224, Split instrument module in Parameters and Instrument modules  #3972, Docs/dataset small fixes #4265, Create public api for dataset. #3536)
• Fixed bug in fallback code for Sphinx extension breaking documentation of certain attributes (Sphinx extension correctly unpack default.  #4223)

New Drivers:

• Add Keithley 2634B model to 2600 driver (Add Keithley 2634B model to 2600 driver #4290)

Improved Drivers:

• The Keysight N52 series drivers have gained a parameter to control RF output. (Add RF output parameter for Keysight N52xx driver #4301)
• Improved Keysight N51x1 driver: make frequency option detection compatible with multiple options installed on device. (fix option detection on Keysight N51x1 driver #4342)
