Feature description
From Agile 1.6.7, a new feature was added - Added async board update. In other words, it is a real-time Agile board. If you change something on it, then it is automatically and visibly applied for anyone else.
We will show you an example for one logged user in Redmine doing changes and other anonymous (i.e. not logged in Redmine at all) will see the changes instantly.
Please see the below screenshot reference. On the left, we use have a Mozilla Firefox browser with admin logged-in user. On the right, we have anonymous user (not logged-in) that has opened the same Agile board, the browser here is Google chrome. And we move this ticket "Swimlanes" as admin user.
As a result, it is now in the "in progress" column in the anonymous user board too at the same time when we just dropped the ticket.
How to enable/disable the feature?
To switch on or off this functionality, please go to Administration (on top) - Agile - General tab. And here, scroll down to the bottom and check or uncheck the last option that says Real-time agile boards. Please see this picture to make the situation clear.
