It would be helpful to have an indication of what goals related to releases and initiatives on the dashboard page (probably also other places on the platform as well). The user can then easily gauge how the releases and initiatives links up to your goals. To keep the page clean and save space, this could be done by using icons.
Using the Reports -> timeline page, you can fully customize a roadmap with information related to your goals, releases and initiatives (as well as additional criteria). You can also fully customize the bars and look and feel of this chart.
