    • 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:

  • Add optional shape metadata to dataset (2145)
  • Allow string and time/datetime data to be stored in array measurements (2313)
  • KeysightB1511B SMU driver has been added for support with the B1500 (2278)
  • 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)
