===========================
The October 2020 release of QCoDeS.
Breaking Changes:
_________________
- A number of long deprecated drivers have been removed:

* ``QDac`` driver: Use ``QDac_channels`` driver as an alternative (2314)
* ``keithley_2600``: Use ``keithley_2600_channels`` as an alternative (2315)
- In the ``QDac_channels`` driver a deprecated parameter (``fast_voltage_set``)
and a deprecated method (``read_state``) has been removed (2314)
New:
____

- Notebook: Example of how buffered sweep could be done on param with setpoints (2263)
- Add ``allow_changes`` option to ``set_to`` method of ``Parameter``, and
add another context manager for restoring current value (2220)
Improved:
_________
