It’s not often you need to look at the detailed history of a task (card) but sometimes you need to know exactly what happened, when, and who did what.
Our latest version has a much improved Task History, as you can see from these examples:
Every change made to a task is logged and the HISTORY tab of the task details dialog shows you not just who made a change and when, but also what the change was.
Where attachments were added, these are shown as links so you can quickly view it by clicking on the link.
Status changes show the old and new values for the status.
Due date changes also show the old and new due dates.
When it comes to sub-tasks (checklist items), the new history view is greatly improved:
You can see every instance of a checklist item changing, including renaming (editing), changing the assignments, and changing the due dates.
