Cylc 8.1.0

Warning

Workflows started with Cylc 8.0 which contain multiple flows cannot be restarted with Cylc 8.1 due to database changes.

Graph View

The web UI now has a graph view which displays a visualisation of a workflow’s graph:

Family & cycle grouping as well as the ability to view graphs for stopped workflows will be added in later releases.

Support for viewing more log files, syntax highlighting, searching and line numbers are planned for future releases.

Edit Runtime

The web UI now has a command for editing the [runtime] section of a task or family.

Any changes made are broadcast to the running workflow.

Combined Commands

Two new commands have been added as short-cuts for common working patterns:

cylc vip

Validate, install and plays a workflow, equivalent to:

cylc validate <path>
cylc install <path>
cylc play <id>
cylc vr

Validate and reinstall a workflow, then either: - reload the workflow if it is running. - restart the workflow if it is stopped.
