Every task keeps a history of its changes: what changed, who changed it, and when. Use it to follow a task's progress, find out who moved a due date, or work out why a task looks different from yesterday.
Open the History tab
Open the task from any task view, such as a project's List or Board, All Tasks or My Tasks.
Click History at the top of the right-hand panel, next to Comments.
The task always opens on Comments. The comment box is hidden while History is open: click Comments to go back to the discussion.
The newest change is at the top. Older changes load as you scroll. Each entry shows the person's picture and name, what they changed, and the date and time in your own time zone.
Anyone who can open the task can see its History tab. That includes external contacts who are members of the project.
What the History tab records
- Creation: who created the task, and who it was first assigned to.
- Status: each status change, and when the task was completed.
- Assignees: people added or removed as assignees.
- Dates: the start date and due date being set, changed or cleared, with the old and new dates.
- Priority, estimated hours and % complete, from the old value to the new one.
- Name and description: renames show the old and new name. For the description, the history only notes that it was updated.
- Moves: to another section or project. See moving tasks between sections and between projects.
- Task type changes.
- Tags, followers and attachments added or removed, by name.
- Custom fields: values set, changed or cleared. See custom fields.
