The November 2019 release of QCoDeS

New:

  • Introduce 'safe experiment abort' feature: On ctrl-c the running experiment
    will be halted, but ongoing VISA commands will be completed and all captured
    data will be written to the database, so that the system is left in a clean
    state.
    A second 'ctrl-c' event will stop the execution without any of those safty
    measures and will thereby reproduce the previous behavior of a single 'ctrl-c'.
    (#1701)
  • Added validation of station configuration files, including live
    linting and auto-complete features for vscode (#1759).
  • Enable setting parameters on ChannelLists in the station config file (#1785)

Improved:

  • Complete overhaul of the parameter cache including GetLatest.
    This improves API experience, removes dangerous bugs as well as sources of
    potential new bugs. (#1757, #1790, #1789, #1768, #1787, #1788, #1827, #1832)
  • Enable logging from multiple processes at the same time (#1816)
  • Documentation: Add new documentation (DataSet #1715), remove outdated
    documentation (#1779) and improve existing.
    (#1780, #1771, #1770, #1781, #1777, #1798, #1803)
  • Added more and fixed type Annotations.
    (#1769, #1797, #1794, #1795, #1807, #1811, #1814, #1815, #1817, #1822)
  • Added name kwarg for initialising Measurement objects (#1741)
  • Bugfix: properly write complex standalone parameter to DB (#1823)
  • consistent snapshot_base signatures. (#1768)
  • enable customized log messages for measurement start and end events (#1808)

New Instrument drivers:

  • Driver for AimTTi Pl601-P (#1763)

Under the hood:

  • Deprecation decorator for classes (#1805, #1806)
  • Improved CI/CD (#1774)
  • Make tests less flaky (#1772, #1826)
  • Docs build on sphinx 2.2.0 (#1783)
  • Getting ready for python 3.8 (#1793)
  • Mypy version 0.740 adaption (#1794)
  • Consistent linting through .pylintrc (#1804)
  • Fix local docs built (#1803)

Breaking Changes:

  • The name and short_name attributes of InstrumentBase became
    read-only properties because it should not be possible to change them on
    an instantiated instrument. (#1820)
  • deferred operations have been removed (#1818).

Deprecations:

  • There has been a great contribution of community drivers over the years and
    and encourage the community to further contribute. To ensure a continued high
    quality standard of the 'core' drivers and reduce the latencies of contributed
    drivers we split out drivers for devices that are not being used within the
    Microsoft Quantum Program into a separate repository that will be community
    maintained. Find the qcodes_contrib_drivers here:
    https://github.com/QCoDeS/Qcodes_contrib_drivers
  • Module qcodes.utils.zmq_helpers (#1819)

Recommended Dependencies:

  • numpy 1.16.4->1.17
  • pyvisa 1.10->1.10.1
  • websockets 8.0.2->8.1
