Cylc 8.2.0 Released

Cylc Cylc Announce
5

We have released cylc-uiserver 1.4.0.

This update upgrades cylc-uiserver to work with the most recent versions of Jupyter components, namely:

  • Jupyter Server v2.7+
  • Jupyter Hub v4.0+

This release offers some big improvements for sites looking to deploy the Cylc GUI with Jupyter Hub:

  • Users can now be authorised to start UI Servers on behalf of other users.
  • There is now a box in the top-left of the GUI for switching user / deployment.
  • The Cylc UI Server can now be deployed along with the latest versions of Jupyter Lab.

Upgrading an existing Jupyter Hub deployment to use cylc-uiserver requires some extra configuration due to the new authorisation frameworks in Jupyter Hub and Jupyter Server. For more information on how to set up a Jupyter Hub deployment with cylc-uiserver 1.4.0 see this page:

Jupyter Hub compatibility

(note this only applies to sites which wish to deploy cylc-uiserver using Jupyer Hub)

  • For cylc-flow 8.2.x, we will continue to maintain both cylc-uiserver 1.3.x and 1.4.x:
    • Use cylc-uiserver 1.3.x for Jupyter Hub 1.4 - 3
    • Use cylc-uiserver 1.4.x for Jupyter Hub 4.0+
  • From cylc-flow 8.3.0 onwards, Jupyter Hub 4.0+ will be required.
