The cylc set command can now be used to satisfy xtrigger prerequisites. For example if the task 2026/get_data is clock triggered, you might satisfy this prerequisite like so:
$ cylc set myworkflow//2026/get_data --pre xtrigger/wall_clock
See cylc set --help for details.
The default behaviour of the cylc set command has also changed for tasks where success is optional, it will now set the succeeded output (and any other outputs that are required in the event of task success) which is more consistent with the behaviour for tasks where success is required.
