The release planning view is designed to let you view the backlog items that have been created for the project and associate them with different releases defined for the project. The backlog items can be requirements or incidents, and in the case of requirements, you can see the tasks and test cases associated with a specific requirement.
The ‘Unassigned Items’ section at the top allows you to see all the items not currently planned, and you can then drag and drop them into one of the lower sections that correspond to a specific release. Using the scroll arrows you can cycle through the releases and move any items from one release to another.
The header of each release section shows the overall progress and utilization of the release:
Clicking on the Release hyperlink will switch the planning board into the ‘Release Backlog’ view described in section 13.3 below.
