QCoDeS 0.35.0b1

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.
