I've been following a few projects' releases over RSS to determine see new releases and when to upgrade docker images I use locally.

For some software, it's not worth it to upgrade straightaway to a new release(eg on a new v13.0 release). I like to see if there are any new bugfix releases afterwards in the coming days or weeks.

On Github.com, a project/repo's releases RSS link follows this format:

https://github.com/{username,orgname}/reponame/releases.atom

Rss for tag feeds are at:

https://github.com/{username,orgname}/reponame/tags.atom

I know for Docker you can/could use Watchtower to upgrade your software or send notifications when upgrades are available. I should look into watchtower anyway and its email notifications .
