History tab
What you can do on this page
The History tab is an audit feature that shows all activity on a project either today, yesterday, over the last seven days, the last 30 days, or since the project began.
Clicking the History tab displays by default all cards were updated today.
Here you can either browse a straight list of project changes, or filter changes according to card properties. You can list changed cards according to their previous properties and/or their current properties. For example, you can view all cards that were open yesterday and closed today.
