We have added an API and UI component to approval jobs that allows you to “cancel” the approval job. Previously it was not possible to cancel approval jobs. This limitation forced you to either approve the job or let it expire, which takes 90 days. This led to a suboptimal experience with jobs left in a non-terminal state. This could impact performance metrics, as well pipelines views. It also led to non-intuitive actions being taken like cancelling the workflow which cancels all remaining jobs.
We are following up this feature with more flexible require statements. So you can have a job depend on an approval while another depends on cancellation. This is great for cleanup jobs, notifications, or other tasks that may only need to happen or not happen upon cancellation.
