changelog page - split into different projects?

right now i think we do an OK job showing folks changelogs but we're not much better than what github shows, minus custom css.

one major drawback to github releases, particularly for monorepos is that it shows the releases all in a single page. we have the opportunity to split that out into different pages.

if folks are using a tag structure like the one cargo-dist requires (project-v0.0.0) we could use that to identify the different projects in the repo and show a changelog page for each project.
