Try the Release Burnup Burndown Chart offered by our Great Gadgets app. It allows you to display milestones for the release in the burndown/burnup chart. A past milestone will be displayed in red color, if the Remaining work at that time was higher than Ideal Burndown, or in green color if it was lower, thus indicating if the milestone was reached or not.
The gadget supports both classic and next-gen projects.
