NICOS 3.10 has been released

NICOS 3.10 is now available for download.

Changes in this release series:

  • Core

    • Added an experimental InfluxDB backend for the NICOS cache.

    • The cache supports prefiltering history by a minimum time interval, speeding up query execution.

    • The lowlevel parameter is replaced by finer-grained visibility.

  • Commands

    • Use of time.sleep is now warned about, users should use NICOS' sleep instead.

  • Devices

    • Added a general slit based on two-bladed gap devices.

    • Added a method to query the preset on the generic detector.

    • The SECoP integration has been updated, and the frappy package is now not required on the client side.

    • On classes inheriting from Device, it is now a hard error to set attributes with names not starting with _, except if they are NICOS parameters.

    • Data sink devices are now hidden from the user by default.

    • The order of calling data sink handlers can now be configured by a new class attribute.

  • GUI

    • Device targets are now displayed in a new column in the devices panel.

    • The SSH tunnel option can now be configured in the GUI.

    • Large scan metadata will not be transferred to the GUI anymore, speeding up transfer of datasets.

    • The point number can now be used as an X axis in scan plots.

    • The scan plot should now use the same color series for each new graph, making them easier to compare.

    • Building installer packages for macOS is now supported. Packages will be available on our website <https://nicos-controls.org/download>_.

    • Qt 6 is now supported. At the moment, support is experimental and needs to be activated using the environment variable setting NICOS_QT=6.

    • “Measure” type commandlets can now specify arbitrary presets, not only time.

    • The guiconfig can now specify default connetion presets for the GUI client as an additional option.

  • Other

    • A /pause meta-command has been added to the CLI client.

    • For watchdog conditions, a “precondition cooldown” time can now be configured.

    • Additional help topics can be added to each setup, and they will be displayed in the GUI/CLI help section for the setup.

    • The LDAP authenticator can now query multiple LDAP servers.

    • The email notifier can now connect to an SMTP server requiring login.

    • The electronic logbook daemon can now be configured to use multiple backend handlers at the same time.
