Whenever a resource undergoes a change, its version is updated and the dependent step is triggered. This is the default behavior for all input resources. To skip steps in a run when input resources are not updated, add the newVersionOnly tag and set it as true. During a run, the step is triggered only when the resource is updated. If the resource is not updated, the step is skipped and all the downstream steps are skipped as well.
