QCoDeS 0.24.0 - March 2021 update

Changelog for QCoDeS 0.24.0

The March 2021 release of QCoDeS.

---

Breaking Changes:

• Because the mode of the Infiniium instrument driver is no longer set in the constructor, the change introduced by #2837 is a breaking change.

---

Improved:

• Support export to xarray for data with non unique indices (#2848).
• Update use of Slack API in qcodes.utils.slack.Slack class (#2813)
• Support dataset export to NetCDF or CSV after measurement ends (#2782)
• Export more metadata to xarray dataset (#2854)

QCoDeS 0.23.0 - February 2021 update

Changelog for QCoDeS 0.23.0

The February 2021 release of QCoDeS.

---

Improved:

• Commit data directy to dataset cache (#2667) (#2761)
• Removed duplicate get call in _ParamCaller used to acquire
  parameters out of the main thread. This fix resulting in a 2x speed up for multi-threaded experiments (#2712)

  list/tuple of guids was flawed. Improvment to use ast.parse makes it a lot easier and error proof. (#2700)
• Fix for station snapshot of parameters with snapshot_exclude (#2692)

---

New drivers:

• AWG Driver for the Keysight M9336A PXIe I/Q Arbitrary Waveform Generator. This driver provides
  a simple wrapper around the IVI-C drivers from Keysight (#2613)

  provided by Keysight (#2613)

---

Improved drivers:

• Feature to determine the frequency and power parameter validators on the Agilent E8527D microwave
  source based on the installed options (#2690)
