Milestones are a great way to show event dates on your roadmap. Drag and drop a Milestone from the sidebar onto the timeline to show an event across the entire roadmap. Or drop a Milestone onto the top of a Lane to show the Milestone for just one lane. Milestones represent the End-of-Day, so they will align with the end date of a bar.
Milestones can be added to the Timeline, or to the top of any Lane. If you have milestones that overlap, you can stack them by dragging one above or below the other. You can create up to five sub-lanes for stacking milestones.
Milestones are visible when you Share, Version, or Export your roadmap.
