The Tasks tab contains the tasks configured in the template on which the release request is raised. Under Tasks, you can add, trigger, edit, organize, delete, and close tasks necessary for the release development. In addition, you can sequence tasks by marking dependency between them.

The Approvals tab displays the approvals configured in the workflow associated with the release request. Depending on your permissions, you can perform approve, reject, and delegate approvals.
Users with stage edit permission can directly create approval levels from the Approvals tab of the current stage. If an approval level is awaiting approvers response, you can add more approvers to speed up the process.
