I’m interested in finding projects that have bug databases (eg bugzilla) that allow people to access them, especially if the available data includes histories for comments and state changes. Ideally, it would include bug reports and feature requests submitted by both the dev team and by users and would have a fair amount of traffic.

To be clear, I don’t mind if the bug tracking software or the project is open source (although that helps). I’d just like something where I can access status and histories over time on a relatively current project.
