Version check for new stable release?

[RBoy]

Stavo guardando questo post sull’utilizzo di una versione specifica:

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.

Quando guardo su GitHub vedo i branch stable o tests-passed (non tag). Tuttavia, vedo un tag latest-release. Qual è la differenza tra stable (branch) e latest-release (tag)?
