Version check for new stable release?

[RBoy]

Я изучал этот пост об использовании конкретной версии:

How would I install a certain (old) version of Discourse

Checkout the same version of discourse_docker that you use on your other server, maybe copy your app.yml from the old server and make the necessary changes. Also in app.yml, change the version from tests-passed to either a tag (e.g. v2.5.0.beta7) or use a git commit hash.

Когда я смотрю на GitHub, я вижу ветки stable или tests-passed (но не теги). Однако я вижу тег latest-release. В чём разница между веткой stable и тегом latest-release?
