Ask HN: How do you track FOSS releases, changelogs?

So I realized this morning (after seeing the post re: NodeJS release) that I'm always having a hard time tracking release notes, breaking changes, new features, etc. It's hard even for the software I'm intimately familiar with and use on a daily basis, and I'd like to get a better forest-level view of the projects I'm using or considering. Does anybody have a resource or tool that aggregates this sort of information? That lets me filter/select the ones I care most about? I'd love to see something like that. Free product idea if it doesn't already exist. ;-) Features I'm hoping for, in no particular order: - Reasonably common format - Filtering/Selecting - FOSS itself, of course
