We are pleased to announce the release of Cylc 8.1.0!

This release includes several new features including:

  • A new “log” view in the GUI for viewing workflow/job logs.
  • A new “graph” view in the GUI for viewing tasks and dependencies.
  • Command line shortcuts for the common “validate-install-play” and “validate-reinstall-(reload|restart)” working patterns.
  • Broadcast edit (a replacement for the Cylc 7 trigger-edit) in the GUI.

As well as many general usability improvements.

Feedback

We have released cylc-flow 8.1.2 and cylc-uiserver 1.2.1

These contain a few bugfixes including:

  • Issues where tasks were missing in the GUI for workflows with nested families, especially where inherit = None is used.
  • Additional rules for the Cylc linter.
  • Fixes and improvements to task filtering in the GUI

For a full summary see the changelogs:

Special Note

Workflows running with Cylc 8.1.1 or lower may display incorrectly with the new version of the GUI (cylc-uiserver 1.2.1). This is due to an unfortunate bug which we were unable to provide back-compatibility for. If you are using the GUI to view workflows running at different Cylc versions we strongly advise restarting workflows with Cylc 8.1.2 to avoid any issues.

We have released cylc-flow 8.1.3 and cylc-uiserver 1.2.2

  • Fix an issue where a scheduler could crash on restart or reload if changes were made to the prerequisites of an active task.

The cylc-ui has been updated from 1.5.0 to 1.6.0 which has an improved log view.

We have released cylc-flow 8.1.4

This fixes an issue accidentally added in Cylc 8.1.3 with the legacy Cylc 7 host configuration, [runtime][<namespace>][remote]host, when used in combination with subshell evaluation e.g. $(rose host-select) which caused the subshell to evaluate as localhost in all circumstances.

[runtime]
    [[my_task]]
        [[[remote]]]
            host = $( rose host-select )

The Cylc 8 equivalent [runtime][<namespace>]platform continues to work correctly at Cylc 8.1.3.

Cylc 8.1.4 also makes more log files available to the GUI in certain situations.
