Quick Road Map (Advanced)
The Quick Road Map gadget displays upcoming releases. This gadget requires the Advanced Edition of Quick Filters for Jira Dashboards.
Only versions from the work items matching a specified project, saved filter or JQL query are shown. Quick Road Map can show versions from up to 5000 work items. Due to technical reasons, the limit will be lower, if multiple versions are linked to a single work item. The limit scales dynamically based on the number of versions per work item. If we cannot show data from all matching work items, a warning would be shown.
